Steel Building Price Per SQFT Quick Facts

One of the most common questions from people looking to buy a prefabricated steel building is, “How much does a metal building cost per square foot?” Unfortunately for the person requesting the information, it’s often a disservice for a steel building company to provide a range such as $18-$25 as an all-encompassing per square foot price. In fact, if they do, that may indicate bigger problems ahead. There’s simply too many factors at play such as location, time of year, design, size, accessories, labor, unions and even the global economy, but we’ll dive into all of that shortly. These 8 factors that affect the cost per square foot of metal buildings are often hidden in the details.

Factors Resulting in Lower Cost Per SQFT

  • Larger buildings, typically above 5,000 sqft
  • Low snow load, wind speeds and seismic activity
  • .5 to 1:12 roof pitch
  • Quality of the steel

Factors Resulting in Higher Cost Per SQFT

  • High snow, wind and seismic conditions
  • Unique roof elevations including pitch and hips
  • The number and types of customizations added
  • Rising steel prices domestically or globally

Factor #1: Know What You Want Up Front

We spoke with Vice President of General Steel and building expert, Lauren McCain, to get a better understanding of just how buildings are priced. “Many customers assume size is the only factor in steel building cost per square foot, but there are numerous other variables at play,” McCain said. Here are a few pieces of the metal building cost puzzle you need to consider.

“Making sure you know what you want up front and making sure the sales person understands your design is one of the most important factors in saving on your final cost.”

The Size of Your Building

As you can see below, economies of scale play a big role in pricing a building system. Below are average costs per square foot for small, medium and large I-beam metal building systems.

16' x 21' $18 per SQFT
40' x 60' $14 per SQFT
50' x 100' $15 per SQFT
100' x 200' $10 per SQFT

The Customizations You Add

The metal building components are what really makes an aircraft hangar distinctive from a garage or workshop and an office building different than an Ace Hardware store. Below are some of the most commonly selected components that can add functionality to a steel building.

I-Beam Standard Features

  • Primary and Secondary Framing
  • 1:12 Roof Pitch
  • 26 Gauge Roof and Wall Sheeting
  • Fasteners
  • Sealants and Flashing
  • Deluxe Trim Package
  • Ridge Cap
  • Plans and Drawings

Popular Additions

  • 3070 Man Door
  • Sectional Door
  • Roll Up Door
  • Horizontal or Vertical Slide Windows
  • Insulation
  • Insulated Stucco Panels
  • Light Transmitting Panels
  • Gutters and Downspouts

Pitfalls to Avoid

It’s important that you choose a reliable steel building supplier. Some suppliers are eager to give potential customers the lowest quote possible. That quote, while seemingly an unbeatable deal, is low because it isn’t accurate. It fails to take into account all of the variables that go into pricing, such as seismic activity, snow loads and customization options that result in the best metal buildings. If it seems too good to be true, it probably is. As McCain notes, another issue in immediately jumping on the lowest quote is the quality of work you receive.

“Cheap structures are cheap for a reason. General Steel structures are made with solid, all-American, I-beam construction with a 50-year structural warranty. The cheaper companies offer no warranty and typically are tube steel or weld-up structures.”

So how do you know the quote you receive is accurate? McCain says to give the supplier a call. “Call a sales associate, and they’d be glad to help you. It’s difficult to know if it’s accurate on your own. Our staff will review any quotes you get and make sure you’re getting what you need, with the correct loads and codes.”

Taking the time to do your research will ultimately lead to lower costs and a higher quality product.

Factor #6: Location

Metal buildings are engineered with your location in mind. Local codes and loads must be met or exceeded, so it’s important to communicate exactly where you plan to erect your building. For example, if you’re in the northern United States, wind and snow loads must be considered, while if you’re planning on building on the West Coast, seismic conditions will be factored into pricing.

Technically speaking, these engineering factors are called atmospheric conditions and as you can see there are even some areas that must account for multiple factors

Factor 8: Building Complexity

Metal buildings are no longer confined to industrial developments. Today, steel building kits are used for everything from personal garages and workshops to elaborate casino buildings and whiskey distilleries. Each building project requires its own custom designed building system and depending on the intended use, the design could be more simple or complex. For example, a simple 40×60 auto shop design would feature a 1:12 roof pitch and one x-braced bay, resulting in a lower cost per square foot building than the same 40×60 space that needs to accommodate an interior crane system.
