Cost Of Metal Buildings – 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 $16-$20 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.
While this is not an exact calculation – the cost varies with the complexity of the design, structural loads, finishing options, and of course size – you’re going to find that the price is relatively constant and not particularly difficult to calculate but you need a professional to help you because a seemingly small miscalculation of a few bucks in the beginning can quickly escalate by the time you’re done.
The first thing you should know is that the price of raw steel fluctuates – but, like gas, those fluctuations are almost always increases. Steel is priced according to market variables such as supply, demand, shipping, and grade (or quality) of the steel.
Because of this, you absolutely must lock in the price of your steel building right away, even if you’re a year away from wanting to build. Your Armstrong Steel building is high grade yet Minimal Yield Strength. This doesn’t mean you are purchasing inferior materials.
Minimal Yield Strength is the standard when purchasing structural steel – it is just means you aren’t going to have to pay high dollar for the high density steel used in the construction of railroad ties, for instance.
The size of your building is also one of the most important cost variables for a steel buildings cost per square foot. For the most part, the larger the building, the lower the cost per square foot of the steel building.
Because of the large clear span widths possible with steel buildings the components necessary to assemble a 40 foot wide building are the same as the components you would need for a 100 foot wide building.
In other words, you’re going to need purlin clips on both sizes and because spans can be extended easily by using steel, those clips will function the same, regardless.
When choosing a 40×60 or a 40×300, the rigid frames on both size steel buildings are pretty much identical, so all you’re paying for is extending the length – which doesn’t typically affect the steel building cost per square foot.
Also – consider your location! Are you going to need a foundation? Are you planning on insulating your steel building? Do you plan to have drywall and an exterior finish? Those options require that the structure be engineered to support the additional weight – or loads – as it’s called in the industry.
Windows, doors, and other components will also play a part in steel building cost per square foot. You can save money by purchasing components at direct pricing or buying them locally if you have the right connections and providing the specs to your Armstrong Steel project manager.
When we mention location we’re also talking about geography. Are you in an area which has high snow accumulation or will need to withstand high winds or seismic activity? Perhaps you have dense rocky soil which requires less support (and less concrete and rebar in the foundation) than sandy ground.
The price includes two overhead doors, one 3070 walk-in door, insulation, Letter of Certification, engineer-stamped plans, and freight to the jobsite from our nearest manufacturing plant.
$7.50-$8.50 per sq. ft. for a prefabricated metal building kit (with above accessories)
$5.50-$6.00 per sq. ft. for a concrete slab foundation 4” thick
$3.50-$4.00 per sq. ft. for framing erection with insulation and typical accessories
Total: $16.50-$18.50 per sq. ft. to get in the dry on a concrete slab
