General Steel has delivered thousands of metal building kits designed specifically for virtually every use imaginable. While many of our customers continue to use their buildings for more traditional applications such as warehouses, industrial spaces, workshops, garages and barns, others come to us daily wanting all of the benefits of a prefab metal building but with a more specific use in mind. These “outside the box” thinkers are some of our most valuable customers because they have proven that our pre-engineered buildings can be the best choice for many different projects such as schools, museums, fire stations and even the press conference room at The White House.

About Steel Building Kits

Learn what makes our building systems unique.

By definition, the building systems offered by General Steel are different than any other type of steel building. Our metal building kits are unique because the building system bolts together, and all of the welding is done at the factory prior to delivery. In fact, all of your framed openings for functional necessities such as windows, doors and even skylights are pre-punched before arriving at your job site. These details may seem minor, but these differentiators from other building systems significantly reduce construction costs and make many of our steel building kits do-it-yourself friendly, no matter the type of project.

What’s Included in a Metal Building Kit?

From basic building packages to fully customized solutions.

Our metal building kits come as basic building packages that can be customized in both look and functionality. You do so by selecting various interior and exterior accessories to add to your base building package. This customization process is what takes an ordinary metal building shell and transforms it into a garage, shop or professional office space as seen in the example below.

Included Standard Features

  • I-beams

  • Secondary Framing

  • Wall Sheeting

  • Roof Panels

  • All bolts and screws (anchor bolts not included)

Easy to Add Options

  • Walk, Roll Up or Glass Storefront Doors

  • Windows (horizontal or vertical slide)

  • Insulated Panels

  • Steel Framed Openings

  • Gutters and Downspouts

Choosing a Color Scheme

Choosing the color combination you will use on your walls, roof and deluxe trim package is a great way to personalize your building. Browse through photos of some of our most popular metal building color schemes.

Other than the anchor bolts and the concrete foundation you plan to build it on, each kit will arrive with everything you need to assemble your new building quickly.

Expert Advice

You can pour concrete piers only to save money up front. In the meantime, pour a gravel floor in your building or leave it as is until you are ready to pour a full slab in the future.

Common Misconceptions

How we guide you from inception through completion of construction

Rest assured, a steel building kit is not a square 20×20 cookie-cutter box with limited options; it’s actually quite the opposite. While a basic building is sufficient for many projects, there are a multitude of accessories designed specifically for metal buildings to customize the look and functionality of your kit.

  • How We Help You: The project experts at General Steel will help you determine exactly what building you need for your location and application. We take ample time to evaluate the local requirements, including snow loads, wind speeds, and seismic conditions for your unique geographical location. We also take into consideration the intended application for your new building, because secondary loads – such as cranes and lifts – can change how the building is engineered.
  • In the End, the Design is Up to You: At the end of the day, your steel building kit is based on your personal, customized design. Whether you are interested in upgrading to a best-in-class metal barn, or a more durable warehouse facility with 300 feet of column-free space, your building will reflect your original vision
  • We Are Your Resource: Over the past several decades, we have assembled the most experienced team in the industry. Whether you decide to purchase a General Steel building, our team will do its best to guide you and help you understand why the majority of consumers end up choosing a prefab metal building over the alternatives.

Your General Steel building kit will include everything you need, along with detailed erection instructions to put together the exact building you ordered.

Base Kit + Customizations = Your Personalized Building System

How our steel building kits are delivered.

Steel building kits are a cost-effective and efficient way to get the extra space you need for your home or business in the form of a durable, easy to assemble building. A steel building kit is engineered for your local area, arrives conveniently at your job site on a truck and includes a bundle of I-beams, wall sheeting, secondary framing, roofing panels and instructions providing a step-by-step guide to erect your steel building. In fact, as long as you contact us to make sure the codes and loads will be correct for another locale, these kits can be just as easily disassembled and transported to another location to be assembled again. This is a distinct feature of our building kits – they are both flexible and personalized, and can travel with you should you need to change locations.

Metal Building Kits Compared to Other Construction Options

Making the best choice for your project.

If you need space and have been searching for a solution, you have many different construction methods to choose from. In addition to the kits General Steel provides you have probably run across other options such as: arch style, light gauge, open-web, tube steel, weld-up and even pole barns which are actually made of wood.

While each type of construction seemingly has its pros, most agree that you get what you pay for. Cheaper buildings may come across as a viable option but the reality is, economy buildings can actually be less safe than steel buildings.

Are All Building Kits the Same?

When it’s time to build, you have options.

Steel Building Kits versus Arch Style
If you’re simply looking at a price tag, the arch style building looks attractive. If you see an arch style building next to a rigid frame steel building kit, it becomes abundantly clear that you get what you pay for. The arch building is made of light gauge metal whereas the rigid frame has 26 gauge just in its walls.

Steel Building Kits versus Light Gauge
As you can see, the size of the light gauge primary framing in the top image doesn’t compare to the rigid steel building framing. The design of the rigid steel building allows it to have more tensile strength.

Steel Building Kits versus Tube Steel
Although the tube building may look like it’s comprised of steel, the tubes are actually 14-16 gauge and are surprisingly hollow. As you can imagine, a tube building’s primary framing is much more susceptible to buckling during a storm whereas a rigid building is designed to withstand any weather.
Metal Building Kits versus Pole Barns
Pole barns gained popularity in the 1970s and 1980s but as consumers learned the advantages of going with steel rather than wood, steel buildings became the construction method of choice.
vs. Pole Barns
Metal Building Kits versus Open Web
Despite the appearance of strength, the open web steel building is much less reliable than the rigid steel building kit. Simply put, the voids between the webbing is not as strong as the full steel I-beam.
Metal Building Kits versus Weld Up
Traditionally welding is very strong, but unless you are a welder by trade this style of building is much more difficult to construct. Not to mention, as you go up in size the welding job becomes more and more costly whereas with the rigid frame, the framing bolts together no matter what size it is.
Assembling Your Kit

Get an idea how easily our kits are constructed.

The instructions provided here are by no means comprehensive, but our kits are extremely easy to install. Many of our popular types such as garages and workshops can be assembled over a weekend with a small crew and a forklift or cherry picker.

  • Unload, Open, Organize: Most steel building kits can be unloaded from the flat bed truck using a standard forklift. Once unloaded, open all boxes and organize the parts in a logical manner.
  • Review Instructions: Carefully review the erection instructions and establish safety protocols. Both should be followed for the duration of the project.
  • Attach Columns: Using a forklift or crane, bring the columns into place and attach each column to the anchor bolts.
  • Attach Rafters to Columns: Assemble the two part rafters and using a sling lift the rafter into place with a tag line for control and a crew member on each column to guide the rafters into place.
  • Repeat: Repeat steps until all columns and rafters are installed and attached to one another.
  • Attach Wall and Roof Panels: Once the primary framing is complete, you can install the framed openings and attache the wall and roof panels to complete the kit.
