Steel has fast become the preferred building material of choice because of its many advantages like cost-effectiveness and versatility. Because of that, many steel buildings are being fitted with all the finishes found in traditional structures.
One such essential is insulation.
If you’re wondering what the best insulation for steel buildings is, we’ve got you. This guide will walk you through everything you need to know about insulation for steel buildings.
The Importance of Insulation for Steel Buildings
Many have debated the importance of insulating steel buildings. However, in most cases, insulating your steel building has several benefits you just can’t ignore. These are benefits like:
Reduces condensation
Reduces energy costs
Improves temperature regulation
Better acoustics
As you can see, insulation is no longer an option if you want to get the best out of your steel building. It’s a necessity.
Insulation Options for Steel Buildings
When it comes to insulating your steel building, you have a couple of options. These vary in the material used as well as the method used to insulate.
Blanket Insulation
Blanket insulation, also called batting or fiberglass sheets, is another steel building insulation option you should consider. The “blanket” consists of mineral fibers of rock wool or processed fiberglass. This is processed into a roll that is used to line the face of the building. However, make sure to install it carefully for full effectiveness and durability. To do this, you must use a strong adhesive to secure the sheets to your building.
One of the major advantages of this type of steel building insulation is that it’s inexpensive. It’s also widely available at virtually any big box store, making it popular for DIYers and a feature on most job sites.
Spray Foam Insulation
Spray foam insulation for steel buildings is the best option if your building has obstacles or has hard-to-reach gaps and holes. This is because you can easily spray it onto the surfaces you want to apply it on. The caveat is that it’s also one of the hardest types of insulation to remove. It’s also one of the most expensive.
Foam insulation is one of the best insulation for steel buildings in cold, dusty, or damp environments as it does an excellent job of protecting the inside of the building from external elements.
Loose Filling Insulation
Loose filling insulation is a great solution for odd spaces that are too tight to fill with regular rolls or panels. However, it will sag over time and can absorb moisture which may lead to mold growth. The trick is to know where the best place for this type of insulation is.
Rigid Board Insulation
Rigid board insulation is one of the more expensive but effective insulation options for steel buildings. It’s particularly suited for buildings with flat roofs. Panels are easy to erect and they are designed to block heat or cold effectively. The only caveat to rigid board insulation is that it requires professionals to install it.
Tips to Ensure a Successful DIY Insulation
If you’re planning on insulating your steel building on your own, there are a few things you must take note of.
Determine the R-value and Understand Insulation Ratings
All the insulation options for steel buildings mentioned above have different ratings that make them suitable for different climatic conditions. One of the most important is the R-value. The term “R-value” may sound intimidating, but it just describes thermal resistance. This is the ability of the insulation to maintain constant temperatures despite external climatic factors. The higher the R-value, the better the insulation material works.
Choose the Right Insulation and Follow Instructions Closely
The right insulation for your steel building is determined by the size and design of your building as well as the climatic conditions of your area. For example
If your building has hard-to-reach nooks and crannies, foam is the best option as you can effectively fill these without having to physically reach them.
If you’re in a place that’s humid or experiences a lot of moisture, fiberglass options like blanket insulation aren’t the best. They’re easily destroyed by moisture.
To get the best out of your insulation, you must closely follow the instructions for your insulation type of choice.
Insulation for Steel Buildings — An Essential You Can’t Ignore
Weighing the initial cost of construction against long-term energy efficiency is crucial when deciding which insulation type will best suit your steel building or metal home. The decision may not be as simple as it seems at first glance. But understanding how an efficient form of insulation can save you in utility costs over time could make all the difference.

Are you considering building a metal prefabricated structure? Here’s what to expect when using a do-it-yourself metal building kit.
What to Expect When Building Metal Prefab Structure
Before construction commences, you ought to understand the scope of the project. The size of the construction will considerably determine the complexity of your build. You can use a small metal building kit for faster and cost-effective deployment of the structure. Here is an outline of what to expect from the process:
Time and Labor Commitments
A prefabricated build can be an intensive and time-consuming process. The time and labor requirements of the project depend on the type of DIY metal building kit you are using.
Conventional buildings take longer than prefab buildings. Erecting traditional structures is not as straightforward as with DIY metal building plans.
A traditional construction project typically requires putting together different parts of the building over an extended period of time. Managing this drawn out workflow can be overwhelming. There are usually many different parts, originating from different locations, arriving at different times of the project, all that you have to coordinate to prevent costly mistakes.
Like seasoned construction managers, you have to work in phases to avoid mishaps during construction. You can benchmark the progress of the project at any point during the construction.
Project Management and Timeline Estimation
You can categorize the process of putting up a metal building into three phases. The first involves putting up the trusses and columns for support. In the second phase, you’ll focus on completing and assessing the sturdiness of the main frame. And the final stage involves placing metal sheets in your prefab building.
Contrary to misconceptions, almost half of the time spent on the project will be on the last phase. Many enthusiasts assume that the most challenging phase is putting up the columns.
While putting up trusses and columns can be complicated, a lot can go wrong during the last stage of your project. The final phase is an intricate process requiring a series of panels to complete the structure.
Planning is essential for sheeting the structure to save time and to minimize the risk of redoing the work. But despite the construction challenges, there are a variety of sheeting profiles for cladding and finishing applications. You can choose colors to mimic other materials, such as wood and plastic. The versatility of the finish is ideal for home offices, storage rooms, eateries, and restaurants, among other applications.
Utilizing Do-It-Yourself Metal Building Kits
One of the benefits of using do-it-yourself building kits is that it saves time and labor. The prefab steel building kit is delivered complete with support trusses and columns.
You do not need sophisticated tools for your DIY building projects. The manufacturers can deliver the kit with holes for fasteners and bolts. You will get a guide with numbers corresponding to different sections of the structure.
Building kit manufacturers perform extensive checks to ensure the building is sturdy and durable. The design of the parts is as per your local building codes.
Why Use Steel Prefab Buildings
Steel is the most common choice for metal prefab buildings. The material is lightweight, making it easy and fast to assemble.
Steel has a high strength-to-weight ratio, which makes it suitable for many residential and industrial applications. You can disassemble the structure and move it to another location.
A wooden structure would be much more expensive to construct. Acquiring the materials for the project can take time. The delays imply that you’ll be generating leasing and warehousing costs. With steel buildings, you don’t have to worry about materials lying around.
Another advantage of steel structures is that they require less maintenance than other materials. Wood and concrete require a lot more care than metal prefab structures. That makes steel buildings an even more cost-effective option.
Professional Assistance During the Design Customization
Whether you are building extra storage or a home office, you may need to adjust parts of the structure. Fortunately, steel is versatile and flexible enough to accommodate most changes.
Steel kit buildings do not require an inner column. The absence of such obstructions, common in conventional buildings, allows you to optimize interior space. You can incorporate extensions into the structure in case you need to expand in the future.
Keep in mind that you don’t have to work alone through the design and construction process. You can consult experienced engineering experts to tailor the project to your needs.
Bottom-Line
The time and resources a metal building requires mostly depend on the size of the project. The smaller the construction, the easier it is to erect the structure. Steel is versatile and does not require inner columns. Steel simplifies the building process and allows for adjustments. If you want a custom design, we recommend working with a designer from the first phase. Visit our website to work with Norsteel for your steel building!
Before the 18th century, there were two types of metals that were commonly used. These were wrought iron and cast iron. Though steel was available, it was recognized as a premium material which was very expensive.
However, at the beginning of the 18th century, people realized the strength and cost-effectiveness of using steel for construction. The whole world seized this as an opportunity to use steel as an optimal material for building.
The Complete Guide to Steel Building Foundation Design
It is not surprising today that steel is widely used as the core material when building foundation design. Steel building foundation designs provide quick construction and cost savings. They allow endless possibilities for customization.
These customizations of steel building provide unique benefits to every industry-specific purpose. Below-mentioned are the guidelines that can help you to customize your steel building design options.
Size
When it comes to sizes, there are no standard sizes for steel or metal buildings. You can design every steel building as per your preferences and choices. To know how much square footage of steel you will need, you will have to simply measure it.
Take your time and measure all the aspects that would be a part of the building. This includes measuring the equipment, machine, and office space you will need. When you do this with precision, you will be able to build a building wherein everything fits spaciously.
Quality
There are many suppliers of steel in the steel building industry. Whereas most buyers focus on buying material that is the cheapest, that might not work well for the steel foundation types that last long.
Comparing prices is of course vital as you want to ensure that you are getting a fair market value. However, choosing the cheapest material is not a good option. When the quality is sub-standard or compromised, the building will not be durable.
Height
Steel or metal buildings are usually low-rise and can be used for building one or two-story buildings. Though the standard range for steel building height is 40’, it can at times go even higher. Many city laws give clearances when you want the building to be higher.
The metal building foundation details will require additional planning if you want to construct higher buildings. When considering the height of the building, you should determine how you plan to use the building in the present as well as if any expansions will be needed in the future.
Window, Lighting, and Doors
As with any type of structure, steel building foundation design should include adequate ways of lighting. To be able to easily perform the tasks that your building is built for, there should be the correct number of windows and light fixtures.
When you install properly insulated windows, it can help to reduce utility costs. This is because such windows can help provide proper ventilation and natural light. A steel building can easily be customized to install windows anywhere.
As for the doors, your steel building foundation design should include them in a sensible and convenient location. You will need to put doors in for entry and exit as well as for emergency exit.
Weather Proofing
Inspect the local weather conditions around your steel building design. If the weather conditions are too unpredictable, then you will have to prepare in advance to accommodate them. The same goes if the prospective area is often prone to natural disasters.
If heavy rainfall is often expected, then you will need to add an extra layer of weatherproofing. To withstand hurricanes and earthquakes, appropriate changes to the base foundation structure will need to be considered. Fire exits and safety equipment should be made ready if the area is prone to wildfires.
Get Started with Professionals
Start with planning out your steel building foundation design. Plan out every small detail from the size, to height, to lighting to resistance. Once you have laid out a comprehensive plan, you will know what steel material you need to match your preferences.
Now that you know what you want, Work with Norsteel for your steel building to get help from an experienced and professional team that can make your plan a reality. By planning your design ahead of time, you will be able to discuss the future look of your building in-depth.

In the search for a new building, it is important to explore all possible options. Often, several factors combine to influence which solution will ultimately suit a customers’ building requirements.
It is always important to consider a thorough assessment of your current needs and to compare these to the on-going maintenance requirements of possible building options. It is also important to consider how your structural requirements may change in the future. A customer’s structural needs may change for example, as a business grows over time.
There are several considerations and benefits that are inherent in choosing a structure with all-steel construction. To take this a step further, there are several advantages of choosing a Pre-Engineered Steel Building Solution over many other available steel building types. Here are some of the more popular reasons why customers consistently choose Pre-Engineered Metal Building solutions over all other options.

More Benefits of Steel Buildings — Better Than Wood
Compared to other building materials, the benefits of steel buildings are readily apparent to anyone that wants a strong yet affordable structure for just about any purpose. But when you consider typical wood buildings, steel provides many benefits that simply can’t be matched by traditional wood construction.
While wood may be the most common way to erect a residential building or to quickly create a structure that may not require the demands of steel, nothing quite beats a pre-engineered steel building when you consider longevity, raw strength and quick assembly. That can help make steel much more viable than wooden buildings that are can be erected in any number of ways.
But with pre-engineered steel buildings, the benefits largely outweigh the costs, and today most commercial, industrial and warehousing projects opt for the convenience and strength of steel over the challenges of working with wood.
Save Money and Build a Better Building With Steel
With the various advantages of steel over wood, it’s true that a steel building can actually cost you less than a comparable wood construction. While the raw cost of a wood building is rather low, you’ll likely end up paying for it over time with numerous repairs and other efforts that will be required to keep that wood building standing and in good order.
On the other hand, a steel building will likely sit just the way it was erected with minimal maintenance or other concerns. Over the life of the building, that can mean substantial savings with a building that doesn’t need much in the way of maintenance. After all, wood warps and rots over time, and those slight shifts can represent huge problems when considering the structural integrity of a building, if not the aesthetic ones.
Instead of regular maintenance and other efforts to determine whether your structure is deteriorating in a way that could be unsafe, the advantages of steel construction means that your steel building can actually end up appreciating in value instead of the opposite, primarily because steel buildings stand the test of time. If you end up in a position where you need to sell your building and the land it sits on, that could help put more money in your pocket.
More Strength and Durability
As opposed to wood buildings, which may go up strong and eventually succumb to the elements without proper maintenance and fixes, a steel building is essentially impervious to it all. Rather than winds and storms causing damage, the benefits of a steel building means that your building won’t be any worse for the wear as time passes.
Furthermore, because steel is steel, you won’t have to worry about termites and other pests that can make owning a wood building a pain. Due to inconsistencies in wood products, you may also experience up to about a fifth of the purchased wood going to the scrap pile, which can represent a considerable expense. That’s why even though a wood building may be cheaper to originally erect, the costs quickly align themselves because steel is simply a better and more consistent product.
Indeed, most modern pre-engineered steel buildings are created to withstand the worst that nature can offer, including protection against earthquakes, hurricanes, tornados, high winds, heavy snowfall and flooding, among others. In general, steel is one of the strongest building materials on earth, and even when faced with fire it will reject burning. It’s one of those great benefits of steel buildings, and why many are turning to steel for their next building project.
Final Thoughts
The benefits of steel are well known in the construction industry.
Steel, as it comes from the steel mill, is incredibly versatile. It is this versatility that provides engineers with the flexibility to design steel structures with a high degree of accuracy. Steel is a plentiful resource – we have an abundance of it, and it is a well-accepted material world-wide. Steel has a very high degree of workability, and can be manipulated easily. It can be cut, and welded; shaped and formed so that it satisfies an endless array of requirements. And Steel is resilient. It can take a great deal of abuse and it doesn’t wear down like other materials. Finally, and perhaps best of all, steel is recyclable, and through the recycling process, it does not lose strength.
When we consider that steel is the fundamental construction material of all our Pre-Engineered Steel Buildings, we can see how the benefits and advantages keep adding up: Cost efficient in every way – from materials; to freight; ease of assembly and faster occupancy. Pre-engineered Metal Buildings are virtually maintenance-free and easy to expand; adding continuous value year-over-year in savings and worry-free, enjoyable space.

In their search for a new building, many of our customers quickly recognize the benefits of a steel building solution. But there are different types of steel buildings, and not all offer the same efficiencies and benefits. There are four main types of steel buildings that can fall under the umbrella of being pre-engineered solutions. These are the Quonset Hut and its arch-type variants, the C-channel Metal building; the traditional Rigid Frame Metal Building system and the Hybrid steel building solution. Each of these steel building solutions has its merits, advantages and disadvantages; and each is better suited for specific functions and applications. We have explored the Rigid Frame and C-channel in great depth in previous blogs, let’s now turn our attention to the Quonset Hut and other arch-type steel structures.
Quonsets & Arch-Type Structures
The Quonset Hut was the first pre-engineered steel building which was originally manufactured as a temporary structure used during the World Wars. It consisted of pole arches with sheets of metal cladding lain over top, that were incredibly easy to transport and because of their stack-ability they could be easily assembled, and re-assembled, on the war front.
One feature most appreciated during this time was the ability of the structure to contain and lift when a bomb was detonated inside of it. And of course, because they were entirely made of steel components, the Quonset Hut was fire-resistant.
Tip: The Quonset and all arch-structures, like the C-Channel and Rigid Frame Metal Building Systems are made from 100% steel components. As such, they share an “A”-Fire Rating. Many customers don’t realize that this non-combustibility factor can save significant money on insurance premiums for the life of their pre-engineered steel building.
The Arch – Strength and Integrity
The Quonset Hut serves many great purposes – and truth be told, I have a bit of a protective affiliation for it, because it was the first steel building I was taught to recognize, and to sell. The most amazing thing about the Quonset, is that the integrity of the entire structure remains entirely dependent on the integrity of each individual arch. And anyone who has traveled to Europe and witnessed the historical architecture there, understands the strength of that arch.
That the arch provides the structural support for the building means that all Quonsets have clear-span interior. As is the case for all pre-engineered steel buildings, columns and posts are not required for structural integrity. This means there is nothing to get in the way of 100% usable interior space.
Quonsets are pre-engineered, requiring conformity to National Building Codes and loadings. This means that like all pre-engineered steel buildings, Quonsets must be custom engineered to withstand the loads and codes of the specific location in which they will be erected. Simply speaking, the gauge of the steel determines the ultimate strength of the structure – the lower the gauge of steel, the thicker and stronger each arch will be.
The arches of a Quonset are deep corrugated galvalume steel, and the corrugation itself provides added structural strength to the overall structure. It also provides the exterior of the building so that it is structure and covering all in one. This is part of the economical design of the Quonset – The surface and structure are one in the same.
Depending on the width of the structure, several segments are bolted together to form each individual arch and each arch is then bolted to the next arch in sequence. The arches are anchored to a foundation – usually a floating slab. An industrial base plate which connects the arches to the foundation, is arguably one of the most important components in the construction of all Arch-type steel structures. This plate is extremely valuable to line up the arches properly without any torch or twisting.
Tip: If you are buying a Quonset, make sure to include the base plate connector in your overall cost. This important component, is an optional feature that you don’t want to overlook.
The first Quonsets were frequently referred to as dome structures. Their shiny, half-moon shapes adorn many of our Canadian provinces as it quickly became a fantastic solution for agricultural applications, especially in terms of livestock housing, and crop storage. But customers soon understood that there was a significant amount of space that was being lost on the sidewalls of the Quonset. Because of the structural design of the arch, the sides of these original steel structures, are not vertical and this loss of space on the sides of the structure quickly adds up.
Tip: In comparing Arch-type steel buildings with other pre-engineered building systems one very important factor for customers to consider is the height measurement. The height of an Arch building is taken from the center of the highest component – the highest point of the arch. The height of a c-channel or rigid frame instead, is taken at the EAVE HEIGHT (not at the peak) – where the sidewall meets the roof. For example, an arch building with a listed height of 12′ may be comparable to a gable building with a height of 9′, depending on the pitch.
Structural Security & Aesthetic Appeal
In an effort to deal with this lost space, Quonset manufacturers created several different models of the original arch building.
And although in many of these new designs, the lost space is minimized, there has been a trend away from these arch-type structures for two main reasons: high snow loadings and, aesthetic appeal.
In the last few decades there have been many incidences of unexpectedly high snow fall mixed with heavy rain, in many regions of North America. These unprecedented weather conditions caused structures of all types to collapse. Naturally, the devastation and loss of property evoked significant concern and resulted in the implementation of new and stringent National Building Codes. These new codes in turn, had the effect of limiting the use of large, arch-type structures in many areas, because the gauge of the steel required to pass approval was so thick that it increased the overall building cost dramatically. Quonsets became comparable to other traditional pre-engineered steel building alternatives in terms of price, and were no longer the affordable option for large-scale projects.
Tip: The types of loads and their magnitudes are critically important to the design and construction of any pre-engineered steel building. Both the location of the site where a building will be located, as well as the location and positioning of the building ON THAT site, are extremely important in determining the integrity of any pre-engineered steel structure. If a building is going to be located in an area with obstructions, other buildings or trees for example, then that building must be engineered to withstand the additional snow that may occur as a result of the snow shadow – that is, the redirected snow accumulations that are caused by the positioning of those obstructions, in relation to the steel building. Today, Pre-engineered Steel Building suppliers are very weary of obtaining this vital information from customers. When discussing your project, be certain to share information about your site with your Building Consultant.
At about the same time that the NBC became more stringent, many municipalities also passed Bylaws prohibiting the use of arch-type structures in commercial and residential areas, based on their aesthetic appeal. Several lobbyist groups took up against the shiny surface of the galvalume arches, saying they looked unconventional, industrial and unattractive in municipal areas with high frequency and residential space.
Since it is generally not recommended to apply paint to the arches of these structures, aesthetic creativity and customization are generally limited to the Endwalls of these metal buildings. Many customers are happy to build their own Endwalls out of wood or steel panels in order to adorn the front of their metal building systems.
Tip: If you are buying a Quonset, make sure to find out if both Endwalls of the structure have been included in your cost summary. Many suppliers consider the Endwall an optional feature and include it at an additional cost to the standard kit.
Another factor for some customers is that Door and Window Openings are typically limited to the Endwalls of the Quonset. Recall that the single most important factor in establishing structural integrity in the arch building, is the arch itself. It follows that placing openings on the sides of the arch requires extensive engineering to ensure integrity – at an increased cost. The limited use of door openings on the sides of the structure has implications for both aesthetics and functionality.
All of these things combined have made arch-type structures applicable to a very specific consumer market: Typically those looking for large structures in areas with little to no snow fall; and those customers who are looking for smaller buildings – up to approximately 35’ in width, for use as Backyard shops and garages. Often these buildings are marketed as do-it-yourself kits and, although it can be tedious and time consuming to bolt together each arch into the next with thousands of bolts, the main challenge for DIY customers is to maintain the alignment of the arches without twisting during the erection process.
Tip: As mentioned previously, make sure to discuss the inclusion of the base plate connector in your building quote. This connector will help to diminish the twisting of the arches during construction. Equally important, if you are considering an Arch-type steel structure, find out if your supplier has included the butyl rubber caulking in your cost summary. Many suppliers consider this caulking an optional feature and include it only at an additional cost to the standard kit. But Butyl rubber caulking applied between the arches during the construction process has been shown to reduce the possibility of water leakage in these buildings. It is extremely difficult to apply effectively after the building has been erected.
Closing Out
There is little doubt that the Quonset Hut and other arch-type structures have provided valuable structural space for many customers.
Once a very affordable steel solution, arch-type structures have suffered in popularity as changes to the National building codes and to municipal bylaws imposed stringent guidelines that restricted their use in areas with high snow loads, and in several residential and commercial zones.
As a result, the Quonset Hut and other arch-type steel structures, have become limited to servicing a very specialized segment of the consumer market. Their increased costing and issues with aesthetics, have inspired customers to look into other types of pre-engineered metal building solutions in order to get the benefits previously sought from the Quonset. Pre-engineered solutions, like the C-channel, are beginning to replace smaller arch-type structures because they offer the same do-it-yourself construction, with a more traditional aesthetic appeal and at a comparable cost. And for larger buildings with wider constitutions, Pre-engineered Rigid Frame steel buildings have become an alternative solution, especially in areas where environmental conditions are of high consideration.

Historically, people have turned to wood for construction because it is a familiar material that is “user-friendly”. Pole Barns and wooden structures are some of the most common building structures around. A century ago, wood was easily the best choice for materials and was found in abundance all over the world. It was inexpensive, readily available and owners usually designed and built their own structures because it provided a flexible and very forgiving erection process.
Despite the initial savings in price, over the years, steel construction has become more popular and presents significant advantages over wood. Pre-engineered steel buildings are now the method of choice for most commercial, industrial and warehouse applications. Even the agricultural and livestock sector, which traditionally has relied heavily on wood for construction, is switching to steel.
Here are some of the reasons why steel structures have become the preferred alternative to wood construction.
Comparing Pre-Engineered Metal Buildings to Structures Made from Wood
Greater Structural Strength and Integrity
Steel building components are manufactured to very rigid standards and specifications. There are no seconds or substandard materials in a pre-engineered metal building. Each part in a metal building meets strict industry standards in terms of strength; and is designed specifically for its pre-determined use in that specific metal building. This is important as we discuss the custom requirements for each particular job: Every component in a steel building is designed and manufactured to meet the strict load criteria in each individual structure, ensuring that each steel building will handle all the load requirements of its specific site location. Because of this, properly designed and assembled metal buildings have withstood hurricanes, tornadoes and extreme conditions worldwide.
Quicker, Easier, and Less Expensive to Construct
Each pre-engineered steel building component is designed and made specifically for your building. Each component is designed and manufactured to match perfectly with the others. Each piece is labelled and easy to identify and each piece is cross-referenced on the assembly drawings. This means that your steel building – regardless of size, will arrive as a perfect kit, and each piece will fit together precisely. Because each component is detailed and specifically made for each particular structure, erecting the building is quick and easy. In turn, because Steel buildings are assembled quickly and easily, they require less labour. There is little to no waste and little to no cutting, sawing or welding on-site.
Wood buildings take much longer to erect than pre-engineered packages, simply because all the components are sourced and acquired separately. There is more measuring, more cutting, more margin for error and all of this takes a significant amount of time. It also produces much more waste in total, as components must be made to fit once they arrive to the job-site.
One last consideration is that the price of wood is constantly fluctuating. Frequent lumber shortages drive the cost of wood up. This encourages the use of “green” wood in construction projects which can result in warping, cracking, and splitting. These cracks in the wood members effect seal-ability, which decreases both the energy efficiency and the structural integrity of the final structure.
Riding arenas, like those pictured above, can be built in either wood or steel but steel components are quicker to assemble, safer over the lifetime of the building, and more affordable than wood.
Safer – Over the Lifetime of the Building
Steel components won’t weather or degrade over time like wood. Steel won’t decay. Steel will remain rigid for the life of the building. This structural strength means less stress on fasteners and components; which in turn provides a safer building for years to come.
Alternatively, owners of wooden structures need to invest in continuous maintenance. With wood, wherever there is moisture close to the base, there is an opportunity for decay. Decay causes structural insecurity and increases the risk of collapse. To deal with the natural properties of wood, most wood posts are pressure treated, but this process can be poisonous to livestock or other animals if ingested.
Importantly, wood carries with it the fear of loss due to fire. One very real peace of mind that comes with choosing a Steel building is the security that your people, livestock, and your property, are safe; because steel is non-combustible.
Greater Design Flexibility
Wood structures require more interior columns for support. This takes up valuable floor space that could otherwise be used.
Because steel is much stronger than wood, it allows for much greater design flexibility. You can typically span the entire width of your building with no interior posts required and the columns can be set further apart on the sidewalls. The result is a much more open building with less weight and greater structural integrity.
When wood trusses are used to accomplish wide open spaces, they must be layered and joined in several places. This increases costs exponentially. This is why wood structures typically involve several interior posts and beams that limit the useable, clear span area, decreasing work space.
Lower Maintenance Costs
Steel components won’t warp, split, twist, swell, shrink or decay, like wood. Steel components will not have to be replaced or repaired and will remain long after the wood frame building is gone.
Pre-engineered metal buildings use a minimum heavy 26-gauge sheeting for roofing and siding, as opposed to the light 28 or 29 gauge material used on most wooden pole barns. Fasteners are also higher quality for steel buildings and won’t need to be replaced like on a typical wooden pole building. The light gauge metal sheeting on most wood pole buildings will require replacement over time, and wood runners hold moisture against the light gauge metal sheeting, causing the sheeting and the fasteners to rust prematurely. In such cases, the fasteners lose their grip and the sheeting becomes loose requiring repair or replacement. Additionally, regular high maintenance is required to escape rodents and burrowing insects, and to limit the amount of rot and mold in wooden structures.
When you chose a pre-engineered metal building, these things are not issues. Steel Structures are virtually maintenance-free.
Longer Economic Life – More Durable and Worry-Free
Steel offers maximum functionality while still maintaining the aesthetic quality many seek from wooden buildings.
Steel buildings simply don’t wear out over time like wooden structures. Barring some catastrophic event, your steel building will last a lifetime. Wooden buildings have an economic life of 15-20 years and require lots of maintenance along the way. After approximately 7 to 10 years, wood siding and roofing will have to be replaced. If non-metal roofing is used, it will also require replacement at some point. And as a wooden structure ages, wood members naturally dry out, which causes shrinking, warping, swelling and cracking. Preventing the wooden structural members from drying out is necessary to maintain a secure structure but requires continuous maintenance and a watchful eye.
In contrast, a pre-engineered metal building requires virtually no maintenance and provides decades of worry-free service.
Stronger Foundation
One of the first objections some people make to a steel building is that it requires a concrete foundation and floor, adding significantly to the initial cost of the project. A metal building doesn’t always require a full slab, although it does require concrete piers at each column location to provide proper structural stability and meet design load requirements. The required piers provide load bearing capacity and an above grade connection so that the posts are not subject to moisture and decay. Foundation requirements are dependent on building applications as well as site location. Local permit offices will assist in dictating which foundations will be deemed appropriate for specific buildings and municipalities.
While the foundation does add to the initial cost of a metal building system, the advantages over the life of the building are tremendous and outweigh the original expense.
Steel Construction is Better for the Environment
Steel is 100% recyclable and is the only recycled material that doesn’t lose strength when it is recycled. Remember that there is also no waste when a steel building is manufactured and erected, because no substantial cutting is required on-site and all cut-offs at the factory are recycled.
When compared to wooden construction which is wasteful and non-recyclable, Metal buildings are the best choice for the environment.
Steel Buildings Can Actually Save You Money – Year after Year
Apart from continuous savings related to maintenance, steel buildings are recognized with an “A” fire rating. Wood buildings instead, have a “C” rating for fire. Generally speaking, what that means is that a wood structure is more likely to burn. Many customers don’t realize that this non-combustibility factor can save significant money on insurance premiums for the life of their pre-engineered steel building.
Closing Out
Steel buildings offer many advantages over wood structures.
At first glance, the price savings afforded by a wood building may seem very attractive to customers. But when comparing different solutions for required construction, we recommend that our customers consider all the factors.
Compare all the costs – not just the initial costs for site prep, materials and labour, but also the longer term costs of ownership – costs like maintenance, repairs, and insurance. Decide how much value you place on safety and environmental friendliness, too.
When considering all the advantages, customers agree that the value of a pre-engineered steel building far outweigh the initial cost savings of a building made from wood.

Most customers who are looking for a steel building have a very good idea of what they want their end project to look like. Many customers are familiar with the basic concepts and terminologies that are used to discuss structures in the Metal Building industry. All customers can benefit from a good understanding of measurements and dimensions as they process the information that they receive from their metal building provider and interact with their building consultants.
In this blog, we provide an overview of the pre-engineered steel building system. We will share some of the more popular steel building designs and go over the basic concepts of a metal building system. It is important to take some time to explain the important measurements that customers need to know and understand before they begin their search for a metal building provider.
The Metal Building System
Steel, also known as red iron, is used across a multitude of industries in the construction segment.
The Properties of Steel – What Makes Steel so Great?
The primary advantage of a steel building is its strength. Steel, as it comes from the steel mill, is incredibly versatile. It is this versatility that provides engineers with the flexibility to design Norsteel steel buildings with a high degree of accuracy. Steel is a plentiful resource – we have an abundance of it, and it is a well-accepted material world-wide. Steel has a very high degree of workability, and can be manipulated easily. It can be cut and welded, shaped and formed so that it satisfies an endless array of requirements. And steel buildings are resilient. They can take a great deal of abuse and it doesn’t wear down like other materials.
Finally, and perhaps best of all, steel is recyclable, and through the recycling process, it does not lose strength.
Building Designs
All our consultants here at Norsteel Buildings are trained to identify each customer’s specific structural requirements. Requirements are then matched to the steel building design which will fit that customer’s particular metal building specifications. Different applications and different site locations may require different designs, and not all steel buildings are created equally. Even what looks like a simple box has to be engineered to exact specifications.
At Norsteel, we supply pre-engineered steel buildings in all shapes and sizes. Because of their versatility, these steel buildings can be engineered to join to each other and to existing structures, creating an unlimited array of shapes and configurations.
Here are some of the more typical metal building designs:
I. Double Slope/Gable Steel Building
The gable steel building is a symmetrical steel structure – it is by far the most common Norsteel metal building design produced. It offers an unlimited number of optional features and is used for an unlimited number of applications.
Double slope metal buildings can also be designed to be a-symmetrical, when customers require that the peak be off-set for a specific application.
II. Single Slope Steel Building
The single slope metal building is used for several specific applications ranging from agricultural storage, to commercial facilities with solar panel installations. Single slope steel buildings are well suited in spaces with multiple structures to accommodate snow shadow from existing buildings. The single slope steel building is designed to be self-supporting.
III. Lean-To Steel Building
A lean-to steel building is designed to attach to another steel building system, or to an existing structure. It typically uses the structural support of the existing structure on the attaching side. Typical uses include car ports; porches; and drive through windows for fast food restaurants.
IV. Steel Structures with Mezzanines
Several metal building projects require a second floor. When the mezzanine is attached and supported by the metal building, it must be engineered to maintain the structural integrity of the metal building system. Norsteel can supply pre-engineered steel structures with up to 3 floors. These can be designed as partial mezzanines for viewing galleries, or full mezzanines to provide complete upper floor space.
V. Steel Structures with Cranes
Several metal building projects are designed for warehouses, mines, and manufacturing plants and must be pre-engineered to support 5-, 10-, or even 20- ton, cranes. Some steel structures have several cranes in each building. Our crane buildings are designed with a standing seam roof system to prevent leakage resulting from vibrations caused by the auxiliary load of the moving crane.
Basic Concepts of Pre-Engineered Steel Structures
Most metal building systems have four outside walls. Two of these walls we call the sidewalls and the other two walls we call the endwalls. As their names imply, the Sidewalls of a steel building are located where the roof meets the walls in a line that is parallel to the ground. In other words, Sidewalls are a consistent height. In contrast, the endwalls are not a consistent height (unless the roof is perfectly flat – which is not typically the case in pre-engineered steel buildings). The height of the endwall changes where the walls meet the roof line. Endwalls are named either left or right. Sidewalls are either front or back.
Tip: Many customers think of the left endwall as the front of their building. Make certain you are in alignment with your consultant when you are discussing each wall of your steel structure.
The line where the sidewalls meet the roof on a steel building is called the eave. It usually has trim to make it look nice in appearance and gutters to remove rain flow from the roof. The distance from the bottom of the base plate to the point where the roof meets the wall, or the eave, is called the eave height.
Tip: The eave height is important because in steel structures, we measure the height of the building according to the eave height (not the peak height). Some municipalities impose a total height restriction. If this is the case in your municipality, then your building consultant needs to be informed so that your eave height can be calculated accordingly.
In steel buildings, we refer to the spot where the two sides of the roof meet on the highest point of each endwall as the peak or ridge. The gable instead is the triangular section that runs from each eave line to the peak and from the eave line on one sidewall to the eave of the other sidewall.
Metal Building Packages from Norsteel all come equipped with trim to enhance appearance. The line where the endwall meets the roof is finished with a piece of trim known as rake fascia. The line where the sidewalls meet the endwall is finished with a piece of trim known as the corner trim. And the peak receives a plastic or metal cap that we call a peak cap.
Tip:Trim packages can be an effective way of enhancing the appearance of your steel building system. Trim is available to customers in several standard colours.
Measurements of Pre-Engineered Steel Structures
A thorough understanding of the measurements that determine size and appearance of a steel building is incredibly important both from an aesthetic and functionality point of view.
Roof Pitch
The roof pitch or slope is usually shown as rise over run.
Typical steel buildings can be designed in several different pitches, but depending on their width and application, most steel buildings are designed with a pitch that is ½-in-12 (.5:12 or .5/12), 1-in-12 (1:12 or 1/12), 2-in-12 (2:12 or 2/12) and 4-in-12 (4:12; 4/12).
For small steel buildings, like in the case of a backyard shop and garage, a roof pitch of 2/12 is by far the most common. Larger steel buildings, like warehouses or arenas, typically call for a 1/12 pitch. For buildings requiring a more traditional, residential appearance, a more defined peaked appearance such as an 8/12 pitched roof may be desirable.
Tip: When we are speaking of roof pitch we are looking at how much of a peak the roof will have. Although many customers consider the roof pitch to be incredibly important in order to establish the ideal aesthetic appearance for their steel building, the degree of slope also has intense importance in terms of snow and rain accumulation.
Inches are used as the basic unit for roof pitch. For example, a 2:12 roof pitch means that the roof rises 2 inches for every 12 inches measured horizontally.
Dimensions & Measurements
Like every other product in this world, steel building systems have three basic dimensions: width, length and eave height.The width is the distance from the outside of the sidewall girt on one side to the outside of the sidewall girt on the other side. The length is the distance from the outside of the endwall girt on one end to the outside of the endwall girt on the other end. The eave height is the distance from the finished floor to the point where the roof meets the sidewall.
Tip: When you are speaking with your steel building consultant, make absolutely certain that the dimensions you are discussing are clear. All metal building providers use out-to-out measurements. The interior space will be reduced in order to compensate for the rigid frame itself. If you require a definite clearance within the building, you must make certain to tell your consultant.
The most important message here is that all dimensions are taken from the outside edge of the girt to the outside edge of the girt. Clarifying these “out-to-out” measurements is crucial.
Final Thoughts
When we first meet with our customers, most of them already have a basic understanding of their structural requirements. They know how they want to be able to use their building and what needs it has to satisfy; and they have a good idea of how they want their finished structure to look.
When you are collaborating with your steel building consultant, be sure you are on the same page. When discussing locations for windows and service doors, it is important to be clear where they should be located; when talking about garage door openings or hangar door locations, it is important to understand the clearance factors involved; and when you are discussing interior clear-span, usable space, it is important that you are calculating dimensions based on out-to-out measurements.
Having a basic understanding of the concepts and terminologies used in the Metal Building industry will help customers to ensure that they are communicating the essential information to their steel building consultant. But don’t be overwhelmed.
Your building consultant is an instrumental resource in assisting you to ensure that all your needs are communicated and met. It’s our job to walk you through the entire process and to make sure that your finished steel building is exactly as you envisioned it.

In a previous blog we discussed the different Metal Building Systems in the Norsteel Product line. We touched on the basic concepts and terminologies that are important for customers to understand, as they work with their Building Consultant to design the steel building that will ultimately meet all of their requirements.
As mentioned, Norsteel’s Rigid Frame Steel Building Systems, are by far our most versatile product line. Rigid Frame Metal Buildings can be customized to accommodate unlimited applications and project needs.
This is precisely because of the way they are engineered.
In this blog, we go over the structural support system of Rigid Frame Steel Building Systems. A general understanding of the structural support components will help customers to gain an appreciation of how all the components work together to provide integrity and structural support for their steel buildings. This knowledge is what allows us at Norsteel, to provide our customers with innovative, cost-saving solutions. Because once you understand how the pieces go together to produce strength and support, you also know how to provide unique design solutions without sacrificing that integrity. This in turn, allows us to be creative in our approach to every steel structure.
Rigid Frame Metal Buildings
This diagram provides an inclusive look at the main components of a rigid frame metal building system. Not all steel structures are pre-engineered with all of these components. There are options and necessities which are dependent on the steel building application, the size and, the specific building codes and loadings for your particular building on your particular site. Several components must be added when there is, for example, a mezzanine or a crane in the building; or when there is snow shadow or significant point loads. But for the most part, this diagram is a good place to begin your introduction to the basic elements that make up a simple metal building system with a Rigid Frame.
The Structural Support System
The Structural Support System of a Pre-engineered steel building is divided into 3 main parts:
The primary support system
The secondary support system and,
The bracing system
These 3 structural systems are engineered to absorb the loads and forces that are acting on the building and they transfer those loads into the foundation system.
1. The Primary Structural Support System
When we speak about the Primary Structural Support of a Pre-Engineered Steel Building, essentially, we are addressing the framing of the building. The Primary structural support system is the main support of a pre-engineered steel building. For this reason, we often refer to the primary structural support systems as the main framing system of the building. It follows that when a frame is at an Endwall, it is called an Endwall Frame, and when a frame is within the building, it is called an Interior Frame.
Rigid Frames and Endwall Frames are laid out in a carefully engineered pattern to provide the primary support for the building. The distances between the centerline of each of the frames is called a Bay. Bay Spacing is an important factor in determining the design of your structure. The required width of each bay is something that customers should consider because it will have an effect on where you are able to place windows, service doors, and larger garage, overhead and bi-fold doors along the sidewalls of your steel building.
Rigid Frame Support
The rigid frame is the most commonly used frame in pre-engineered Steel Building Systems, and so it stands to reason that it is responsible for why we identify this as a Rigid Frame Pre-Engineered Steel Building. It is the Rigid Framing System on a pre-engineered steel building which offers the structural integrity to this construction. Without the Rigid Frame, there is no pre-engineered solution.
Generally speaking, a Rigid Frame is designed to bear the load for half the bay of the roof on either side of its location.
Although the majority of Rigid Frames are typically clear-span in design, the Rigid Frame is also available in a modular version.
Rigid Frames are either Clear Span (no interior columns) or Modular (with columns). Modular frames have 1 or more interior columns between the exterior columns, that are responsible for supporting some of the vertical load that is carried by the frame.
Tip: A Rigid Frame can be used in the interior framing as well as at an Endwall of a steel building
Clear Span Rigid Frames
By far the most frequently used primary framing in a Pre-Engineered Steel building is the Clear-Span Rigid Frame. We call these frames “Clear-Span” simply because they have no interior columns or support between the exterior columns. An amazing thing for all customers looking to achieve 100% usable interior space! In fact, it is the Clear-Span Rigid Frame that revolutionized construction and made metal buildings such an incredibly versatile and innovative investment.
The typical Rigid Frame on a steel building has tapered vertical columns and a tapered rafter. These are the I Beams of the steel building – meaning that if you took a cross-section through either a column or rafter section, you would have an I-shape.
Typically, the rigid frame is thickest in the area where the column is connected to the rafter beam. We call this area, the Haunch. The haunch is the thickest part of a Metal Building system simply because it is a load bearing spot in the building – it must support great force, and so, we must reinforce that area with steel.
Tip: Often, we have a customer who is trying desperately to achieve every square inch of usable space. In such cases, we employ a straight column rigid frame instead of our standard tapered column. This also comes in handy when we are trying to achieve a certain clearance under the haunch that we would otherwise not be able to accomplish. Rigid, Clear-span Frames with straight columns are usually less cost effective because they require the building be fortified in other (less ergonomic) areas.
Modular Rigid Frames
Often, a customer does not take issue with having a clear-span design. In such cases, we have the option of using a Modular Frame. Modular frames are simply Rigid Frames with intermediary columns, and the spacing between the intermediary columns does not have to be equal. What is important here is the understanding that these extra columns provide strength and integrity to the rigid frame, redistributing the load of the force exerted on the haunch. And because the columns provide strength and integrity to the overall structure, Modular Frames can be used to bring the overall cost of a structure down. When used where they can be hidden within the architecture (e.g., in aisles or bleachers) the use of a Modular Frame does not impact the overall design of the interior of the steel structure.
The clever use of both types of framing is one way that your experienced Norsteel Building consultant will work with you to achieve the best solution for your specific building. Depending on the application for your steel building, we may incorporate both rigid frames as well as modular frames within the same design.
Tip: The dimensions between interior columns are measured from the outside of the sidewall girt to the center-line of the first interior column. On all other interior columns, the column spacing dimension is measured from the center-line of one column to the center-line of the next column, until the last interior column is reached. The column spacing on the last interior columns is again measured from the center-line of the column to the outside of the sidewall girt.
Post & Beam Endwall Frames
The most common Endwall frames are called Post and Beam Endwalls. As the name implies, Post and Beam frames are comprised of Corner Posts, End Posts and Rake Beams. They are designed to support the load for half a bay of the roof and to support the addition of framed openings for windows, service doors and, garage or roll-up doors.
In some cases, a Post and Beam Frame may be used as an Interior frame. We call this a Recessed Endwall. In such cases, a rigid frame is used to provide a huge overhang porch and the post and beam is used in the second bay as the entrance way. Many farm-house designs are laid out in this way in order to achieve the look of a large covered front veranda. Such designs are also used for drive-through windows of retail outlets, and for some car ports.
In still other cases, the Endwall Frame must be designed as a Rigid Frame, so that the structure is already prepared for future expansion and length may be easily added to the structure at a later time. In this case, we call it an Expandable Rigid Frame Endwall. In some cases, an Endwall may be designed as a rigid frame so that it can be capable of holding the weight of a large opening or hangar door.
Tip: Metal buildings are relatively easy to expand by lengthening, which involves disassembling bolted connections in the Endwall, removing the wall, and installing an additional clear-spanning frame in its place. The removed Endwall framing can often be reused in the new location. Matching roof and wall panels are then added to complete the expanded building envelope.
2. The Secondary Structural Support System
When we are speaking about the Secondary support system of a pre-engineered metal building system, we are referring to the Purlins and Girts. These structural members are the steel components that run horizontally across the roof and walls, spanning the primary framing.
Girts and Purlins are essentially the same with the only difference being their location on the building, and they have 2 main functions: To transfer the loads to the primary framing, and to provide a surface onto which the roof and wall panels are screwed.
The Purlins
We refer to the secondary system that provides structural support to the roof as the Purlins.
Purlins run horizontally between the frames of the roof. They are all-steel, z-shaped members. The purlins on a rigid frame steel building are typically 8 and 10 inches deep, but are available in 12 and 14 inches when loading conditions require thicker reinforcement. The depth of the purlin as well as the spacing, is determined by the engineering itself and is dictated by both the design of the structure as well as its location.
The job of the purlins is to transfer roof loads to the primary structural support system, which in turn transfers the loads to the foundation.
The Girts
We refer to the secondary system that provides structural support to the walls as the Girts.
Girts run horizontally between the frames of the walls and are attached to the columns.They are Z-shaped, similar to the purlins on the roof, and also come in C-shape which can be used around framed openings. The Girts take the loads imposed on the covering system and transfer them to the frames, which in turn, transfer them to the foundation.
The spacing of the Girts, varies with the load imposed on them. The depth of the Girts used in a structure is also determined by the particular loading requirements for that structure. Like purlins, girts are typically 8 or 10 inches in depth. Occasionally, 12 and 14 inch secondary members are necessary for specific applications and site locations.
Inset and Bypass Girts
Endwall Girts: The Girts on the Endwalls are Inset within the post and beam framing. This means that the girt is flush with the primary framing and does not take away any clear space from the interior of the structure.
Sidewall Girts: On the Sidewalls of the structure, standard practice is to provide bypass girts. All software design programs default to this type of girt. This means that the girt bypasses the frames and is attached on the outside of the primary frame line. In many cases, you have the option to recess, or inset the Girts within the framing. When customers are trying to maximize interior space, we use flush or inset girts as opposed to bypass girts.
Tip: It is important to take the diminished clearance imposed by the structure itself into consideration, when determining the actual measurements of interior space.
One last thing to mention when we are discussing secondary structural members of a metal building rigid frame system, is that the Eave Strut is located at the intersection of the roof and the exterior wall. It acts as both the first Purlin and the last Girt. This is important because the building eave height is measured to the top of this steel member.
3. The Bracing System
The final structural support system of a Rigid Frame Steel Building is the Bracing system. As its name implies, the bracing system functions to resist the forces of the elements and to transfer these loads to the secondary and primary framing systems. There are several types of Bracing Systems that are used in Pre-engineered Steel Buildings. The most common are Rod Bracing; Portal Frames and Diaphragm Bracing.
Rod Bracing
Rod bracing or X-Bracing, is by far the most common type of bracing used to brace the building against forces from the elements, on a steel building system. The rod bracing in a steel structure is found in the roof between the rafters, and in the walls between the columns. Where the bracing goes and how much is needed depends on the design of the building and its location. A structure that is situated in a municipality with high wind load for example, will require more bracing than one in a different municipality with mild wind. Likewise, a structure designed with an open wall, will require more bracing than a structure that is completely closed.
Tip: The location of Rod Bracing on a rigid frame steel structure is pre-engineered and cannot be moved on site without seriously affecting the integrity of the metal building system. When you work with your Building Consultant to arrive at a design that you are happy with, one important thing to discuss is the location of service doors and windows. Although both are field located (meaning that their precise and final locations can be determined on the job site), it is important to ensure that the bracing for the building will not interfere with the desired openings.
Portal Frames
Where it is not an option to use X-Bracing in a steel building, or when we require more strength in order to provide rigidity and structural stability to the metal building, a portal frame is used. Essentially, a portal frame is a rigid frame that is pre-engineered to reinforce the steel structure. By lining the bay along the sidewall of the metal building, the portal frame reinforces the structure to resist strong longitudinal loads. Typically, if there is a portal frame on one side of the building, there is also a corresponding portal frame directly across from it, on the other side of the structure.
Tip: Again, here it is important to take the diminished clearance imposed by the structure itself into consideration, when determining the actual measurements of interior space. The portal frame is as thick as a rigid frame and will add significant feet in all directions. Make certain to discuss the minimal clearance available in each bay with your Building Consultant so that you are clear what size door openings will fit in the space.
Diaphragm Bracing
Another type of bracing that is used to establish structural integrity in a pre-engineered steel building is Diaphragm Bracing. Diaphragm Bracing is inherent in most metal building systems, and results from the presence of the cladding – the exterior panels, that cover the primary and secondary framing of the steel building. Cladding provides the building with aesthetically pleasing colour, and it obviously finishes the wall and roof skeleton of the building. In doing so, it provides yet another defensive bracing system against the loadings that impinge on the structure itself.
Tip: There are several different options for Wall and Roof systems. Insulated Metal Panels; stucco finishes, faux wood and brick options – Wall cladding comes in several different configurations and several colours. The possibilities are numerous and will be discussed in more detail in future blogs.
Closing Out
In this blog, we went over the structural support system of the Rigid Frame Steel Building System. We discussed the primary and secondary structural systems and we discussed bracing. We discussed how these 3 structural systems are engineered to work together to absorb the loads and forces that are acting on the steel building and to transfer those loads into the foundation system.
An understanding of these structural components will help customers to gain an appreciation for the engineering behind their steel buildings, and how they are constructed. It will help them to plan for the design of their steel structures and for the location of functional access items like doors and windows. Understanding the structural support systems of Rigid Frame Steel Buildings – how they are engineered to work together and why they are important in the design of their structures, is a great way for customers to begin a dialogue with their Building Consultant. It will also help customers to discuss construction when they are working with general contractors and erecting crews.
Here we have provided a general overview of the structural support system of a Metal Building System that uses a Rigid Frame design. In a future blog, we will discuss other components, things like door and window framing; gutters and downspouts; overhangs, insulation, and other accessories which can be added to all our Pre-engineered Steel building products.

In a previous blog we discussed the different Metal Building Systems in the Norsteel Product line. We touched on the basic concepts and terminologies that are important for customers to understand, as they work with their Building Consultant to design the steel building that will ultimately meet all of their requirements.
As mentioned, Norsteel’s C-Channel Steel Building System, is by far our simplest and most economical steel building system. The C-Channel steel building is aptly named because it is formed from several steel members that have a “c” shape. These are bolted together to form the structural basis for this type of Metal Building system.
We call our Norsteel C-Channel the EasyBuild Steel Building because we began carrying this product line specifically for our Do-it-Yourself Customers who had been asking for a simpler steel building that they could construct on their own.
This blog will provide you with an introduction to our EasyBuild Steel Building Kit. It will give you an overview of the structural support system that gives it strength and the components that give it aesthetic appeal.
What is the Norsteel EasyBuild C-Channel?
History and Origin
Our EasyBuild steel structure can be described as a C-Channel building because it is formed from several steel members shaped into a c-channel. These are bolted together to form the I-beams that are the structural basis for this metal building system.
The Norsteel EasyBuild Steel Building provides the same conventional look of a Rigid Frame steel structure at the affordable cost of a Quonset or wood build. This is because the EasyBuild is a simple structure. There is less design required to engineer it, there is no welding in manufacturing, and it is a lighter gauge structure, so there is less steel.
In fact, our EasyBuild Metal Buildings are affordable and more efficient on every level. From engineering, to manufacturing, to shipping, and even off-loading and assembly; the EasyBuild is the most affordable choice for simple, clear-span space – Especially when customers are looking for structures up to 35’ in width.
Because it is marketed as a Do-it-Yourself Kit that can be assembled with minimal use of equipment (many of our customers assemble with ladders and scaffolding), the savings continue right into the assembly of the EasyBuild steel building. Handy people can easily follow the DIY instruction manual and blueprints to erect their own steel buildings without the use of heavy machinery or crews of workers. The new, innovative creation of our EasyBuild Foundation Kit further increases savings in time and money by decreasing the amount of concrete that is needed in the foundation.
EasyBuild Steel Building – Components
Our EasyBuild Structures have a hot-dip galvanized steel frame. In fact, all primary and secondary framing members in our EasyBuild model are zinc coated. This zinc galvanizing process prevents rust and ensures a long life-cycle of performance.
1. Primary Structural Support System
When we speak about the Primary Structural Support of a Pre-Engineered Steel Building, essentially, we are addressing the framing of the building. The Primary structural support system is the main support of a pre-engineered steel building. For this reason, we often refer to the primary structural support systems as the main framing system of the building. It follows that when a frame is at an Endwall, it is called an Endwall Frame, and when a frame is within the building, it is called an Interior frame.
Interior and Endwall Frames are laid out in a carefully engineered pattern to provide the primary support for Metal Building Systems.
The distance between the centerline of each of the frames is called a Bay. Bay Spacing is an important factor in determining the design of your structure. The required width of each bay is something that customers should consider because it will have an effect on where you are able to place windows and service doors along the sidewalls of your EasyBuild metal building system.
The Primary Framing in our EasyBuild Steel Structure consists of galvanized, C-Channels which are bolted together to form the structural basis of the building. Typically, these c-shaped channels are 8” in depth, but this can change depending on the design and location of the steel building. Two C-Channels bolted back to back form the “I” beam that is equivalent to the primary framing of the Rigid Frame Metal Building System.
Tip: In keeping with the simplicity of the EasyBuild steel structure, Interior and Endwall Frames are created equally, and there are no expandable Endwalls.
Clear Span Primary Framing
By far the most functional component of Pre-Engineered Steel buildings is the Clear-Span Primary Framing system. We call these frames “Clear-Span” simply because they require no interior columns or support between the exterior columns. An amazing thing for any customer looking to achieve 100% usable interior space! In fact, it is the Clear-Span Rigid Frame that first revolutionized construction and made metal buildings such an incredibly versatile and innovative investment.
The frame on our EasyBuild steel building has straight vertical columns attaching to straight rafters. These c-channels bolt together to form the I Beams of the steel building – meaning that if you took a cross-section through either a column or rafter section, you would have an I-shape.
In our EasyBuild product line, the primary framing is reinforced with thick metal plates in three specific spots on each frame:
at the interior center point where the rafters meet and join to form the peak of the building and,
where the columns of the frame are connected to the rafter beams – at the Haunch, on each side of the building.
The center point and the haunch are the thickest parts of the primary framing in the EasyBuild Metal Building system simply because these are load bearing spots on the building. It follows that they must support great force, and so, we must reinforce that area with thick steel plates.
Exactly like the Rigid Frame Metal Buildings, the EasyBuild Primary Framing is designed to bear the load for half the bay of the roof on either side of its location and transfer that loading to the foundation.
Tip: Unlike the Rigid Frame, the primary framing components of our EasyBuild steel structures can be bolted together in sub-assemblies on the ground, where work is faster and safer. This requires fewer lifts and fewer connections to be made in the air by our DIY customers.
2. Secondary Structural Support System
When we are speaking about the Secondary support system of a Pre-Engineered Metal Building system, we are referring to the Purlins and Girts. These structural members are the steel components that run horizontally across the roof and walls, spanning the primary framing.
Girts and Purlins are essentially the same with the only difference being their location on the building, and they have 2 main functions: To transfer the loads to the primary framing, and to provide a surface onto which the roof and wall panels are screwed.
The Purlins
We refer to the secondary system that provides structural support to the roof as the Purlins.
The Purlins on our EasyBuild Structure consist of galvanized z-channels which are 6” in depth. These 6” purlins are standard in the EasyBuild Structure, but purlins may be produced in greater depth to provide greater strength to structures that will be constructed in areas with high snow loads. The depth of the purlin as well as the spacing, is determined by the engineering itself and is dictated by both the design of the structure as well as its location.
The job of the purlins is to transfer roof loads to the primary structural support system, which in turn transfers the loads to the foundation.
The Girts
We refer to the secondary system that provides structural support to the walls of a Metal Building System, as the Girts.
Girts run horizontally between the frames of the walls and are attached to the columns.
Like the Purlins, the Girts of our EasyBuild Structure consist of galvanized z-channels and the spacing of the Girts, varies with the load imposed on them. The depth of the Girts used in a structure is also determined by the particular loading requirements for that structure. Like purlins, girts are typically 6 inches in depth. Occasionally, deeper secondary members are necessary for specific applications and site locations.
The Girts take the loads imposed on the wall system and transfer them to the frames, which in turn, transfer them to the foundation.
Tip: One last thing to mention when we are discussing secondary structural members of a metal building system, is that the Eave Strut is located at the intersection of the roof and the exterior wall. It acts as both the first Purlin and the last Girt. This is important because the building height for a pre-engineered steel building is always recorded as the measurement to the top of this steel member – It is the eave height that is recorded as the height for the building, not the peak height of the structure.
3. The Bracing System
The final structural support system of the EasyBuild Steel Building is the Bracing system. As its name implies, the bracing system functions to resist the forces of the elements and to transfer these loads to the secondary and primary framing systems. The Bracing System for the EasyBuild Structure is accomplished with a combination of Elbow Bracing and Diaphragm Bracing.
Elbow Bracing
Elbow Bracing, is used to brace the building against forces from the elements. The elbow bracing on the EasyBuild Steel Structure is found between the girts and the primary framing system. Thick steel members are used to provide bridges of additional strength and are bolted and bent into position in the corners from the girts to the primary frames.
Where the bracing goes and how much is needed depends on the design of the building and its location. A structure that is situated in a municipality with high wind load for example, will require more bracing than one in a different municipality with mild wind. Likewise, a structure designed with an open wall, will require more bracing than a structure that is completely closed.
Diaphragm Bracing
Another type of bracing that is used to establish structural integrity in a pre-engineered steel building is Diaphragm Bracing. Diaphragm Bracing is inherent in most metal building systems, and results from the presence of the cladding – the exterior panels that cover the primary and secondary framing of the steel building. Cladding provides the building with aesthetically pleasing colour, and it obviously finishes the wall and roof skeleton of the building. In doing so, it provides yet another defensive brace against the loadings that impinge on the structure itself.
Our EasyBuild Metal Building System relies heavily on diaphragm bracing for structural support. This means that the number and size of doors will be limited, especially on the Sidewalls of the building, simply because removing too much of the cladding means compromising the structural integrity of the building.
4. The EasyBuild Paneling System
Wall Panels
The wall panels for our EasyBuild Steel Building come in twelve popular colors with a 40-year limited warranty against chipping, cracking, flaking or peeling. The paint has a siliconized polyester finish with a substrate galvanized coating beneath the paint providing further protection against rust.
The wall panels are continuous from floor to eave and meet or exceed required wind loads. These panels are 26-gauge as standard. All wall panels are attached to the girts with screws that come assembled with neoprene washers. The washers eliminate the potential for rust by preventing damage to the sheeting. The heads of the screws are painted to match the colour of the sheeting. They will not rust, tarnish or turn black.
Roof Cladding
Galvalume roof panels are standard on all our EasyBuild steel buildings. Our roof panels are 26-gauge high-tensile steel with a corrugation depth of 1-1/4”. The Purlin Bearing Rib (PBR) roof system provides a full overlap, which means our buildings are weather-tight, even under extreme conditions.
Rigid-rib panels are designed for long-life and pre-cut to building dimensions. AZ55 Galvalume® is an aluminum/zinc coating, which protects the roof sheeting against rust. It requires no maintenance or painting to retain its original luster and is comprised of 55% aluminum, 44% zinc and 1% silicone.
The AZ55 roof panels have a high aluminum content providing superior protection against rust and backed by a 25-year, limited rust-through perforation warranty. In addition, the self-drilling roof fasteners are stainless steel capped and come fully assembled with a self-sealing neoprene washers for a weather-tight seal and a limited lifetime rust warranty.
Our EasyBuild Steel Buildings come standard with a screw-down Galvalume roof system.
Trim Package
The Trim Package for the EasyBuild Structure is supplied at no additional charge and serves to provide a finished appearance as well as added protection against leaks and the possibility of rodent and insect infestation.
Trim is available in six complementary colors.
Closing Out
Norsteel’s EasyBuild Steel Building System is the ideal choice for DIY projects. In fact, we began carrying this product line specifically for our Do-it-Yourself Customers who had been asking for a simpler pre-engineered steel building that they could construct on their own.
Backed by the same theoretical pre-engineered design as our Rigid Frame metal building system, the Norsteel EasyBuild Steel Building provides the same strong engineering and conventional look of its rigid frame cousin, but at the affordable cost of a Quonset or wood structure.
This is because the EasyBuild is a simple construction with fewer options, making it affordable and more efficient on every level. From engineering, to manufacturing, to shipping, and even off-loading and assembly; the EasyBuild is the most affordable choice for simple, clear-span space – Especially when customers are looking for structures 35’ in width or smaller. This has made our EasyBuild Steel Building a very popular choice for garages and backyard shops.
It took us a long time to come up with a DIY product line that measured up to the Norsteel standards. We even put one together ourselves with our consultant team to make sure it was everything that we were hoping for in a do-it-yourself steel building before we offered it to our customers. The EasyBuild Steel Building Kit is a welcome addition to the Norsteel product line.
When you buy a building from Norsteel, we become your partner throughout the construction process. We work with you, or with your general contractor, to ensure that all your building requirements are met. Your project is our project, and we’ll be with you the whole way through.

Norsteel was initially founded to provide Pre-engineered Metal Buildings for large scope Industrial, Commercial and Warehousing operations.
For years, we focused on designing complex projects for airports, fire halls and hockey arenas. We designed and supplied customers with pre-engineered steel building solutions with multiple cranes, and mezzanines; metal buildings spanning hundreds of feet in width; steel buildings used for shopping malls and churches, and post-disaster buildings for electrical facilities. We provided customers with incredible solutions for mining projects and we shipped them to incredibly remote locations.
This was, and remains, our specialty – large-scale, customized projects which require out-of-the-box thinking and strategy to accomplish. We excel in finding pre-engineered solutions to satisfy conventional architecture and welcome the challenges of new and adventurous projects. Over the past 20 years, our product scope has grown to include an exciting array of diverse applications. Backyard shops and garages; workshops and mini storage; specialized buildings for grow-ops and food storage. We are always learning and always extending our reach. And because we are so passionate about the steel building solutions that we supply, we never stop increasing our desire to push our scope of work and our knowledge just a little bit further.
Continuing to deliver on our commitment to our customers, we are always researching new products, new cladding, new roof systems, and new types of insulation. Our consultants are continuously training on new innovations and new applications. Part of our Customer Satisfaction approach to service mandates that at Norsteel, we are constantly assessing our customers’ needs and adapting our offerings to include all types and sizes of Metal Building Solutions.
Our Pre-Engineered Metal Building Packages
Generally speaking, at Norsteel, we design two main types of pre-engineered steel buildings for our customers:
1. Rigid Frame Metal Buildings
A significant portion of our business is focused on Rigid Frame Steel Structures. One of our greatest strengths in this space is our ability to match each individual project to the building type that has the best suited design.
While there are always subtle differences, our Rigid Frame Packages are actually very similar in terms of their structural components. The structural support system is divided into the primary support framing system, the secondary support system of girts and purlins, and the bracing system. Rigid Frame Metal buildings can be used for all applications – simple to complex; small to large. They provide incredible versatility with virtually no limitations.

Rigid frame metal buildings can be used for any number of applications. They are ideal for small as well as large buildings like those pictured above.
C-channel buildings are named for the “C” shape of the support beams used in them. C-channel buildings are ideal for DIY steel building kits, garages, workshops, and other such residential uses.
2. C-Channel Metal Buildings
Recently, we have added a new product line, the EasyBuild steel building kit, to our list of offerings. The EasyBuild is very similar to the Rigid Frame steel building, but uses a series of back to back c-channels in order to achieve the structural integrity of an I-frame.
Our EasyBuild Models are an ideal offering for garages and workshops which are 35’ in width or smaller. They are efficient and economical, and the best solution for customers who wish to purchase a do-it-yourself steel building project. But the EasyBuild system has limitations that the Rigid Frame does not: The EasyBuild is only offered in a Gable style steel building; it is limited by high snow and seismic loads; and because it relies on diaphragm bracing, it cannot be designed with extensive openings on the Sidewalls of the building.

Our Conventional and Hybrid Metal Building Packages
We often have customers who provide us with architectural drawings and engineering plans that have already been used to organize and plan a Conventional Steel Building project. Through our manufacturing partners, Norsteel has the ability to provide customers with conventional all-steel solutions. Alternatively, we can provide hybrid solutions which incorporate the best properties of a conventional building solution with those of a pre-engineered steel structure. In this way a hybrid steel solution is often the optimal choice because it satisfies a range of conventional applications while maintaining the economic benefits of a pre-engineered steel structure.
Often we have customers who seek our assistance in order to transform their Conventional architectural design into a Pre-engineered metal building solution. These customers understand the advantages that are inherent in a pre-engineered steel building design and want to benefit from the savings in material and construction costs, as well as in the currency they gain as a result of faster occupancy.
Most often, the design team at Norsteel is able to transition the Conventional design into a Pre-Engineered Steel Building project very easily. And the transition does not affect the final outcome of the project in any architectural manner.
Ideally, when you contact Norsteel first, our highly experienced design team and advanced engineering software allows us to design your structure in-house, saving you the initial expense associated with high-priced engineers and architectural firms. Our team of design experts will work with you to completely understand your project and then will provide you with preliminary structural designs to address your specific requirements. Customers will still need the architectural and engineering firms to incorporate all the bells and whistles, but they will do it from the drawings that we provide which will save both time and money.
