Fast Assembly – No Heavy Machinery Required

Our prefabricated metal buildings are simply bolted together. All you need is a weekend, a few friends and you’ll be done before you know it.This is pretty simple for any do-it-yourselfer. Each building comes with an assembly guide detailing how to assemble in four basic steps.

1. Pour a Simple Floating Foundation

Customize a S-Model Building for Your Needs

The best method to maximize your storage capacity.

Take a look at our S-Model steel buildings. We’ve designed them with high sidewall clearance for superior vertical storage, and removed columns from the interior to optimize floor space. If you’re thinking this would make a great warehouse, you’re on the right track. Steel arch buildings are available in widths ranging from 10-60 feet, and can be customized to unlimited lengths.

This sort of versatility can accommodate more than just warehouses and metal storage sheds. Steel structures of this nature make an excellent swimming pool cover, and with some ingenuity can be adapted to a whole host of commercial, industrial, farm, and residential applications. In terms of durability, these rank among the top tier of pre-engineered buildings.

Our construction process allows you to rest easy.

Our metal building kits are easy enough for novices to put together. Even with no prior building experience, you can still put up the S-Model in good time by following the very simple assembly instructions.

American Steel Span is all about quality construction. We invite you to examine the factors that make us such a popular prefab provider:

  • 100% American made – All of our metal building kits are composed of U.S. Steel. The highest grade, heaviest gauge commercial U.S. Steel on the market. Our structures are precision manufactured to meet or exceed industry standards. The results? A sturdier construction that is better equipped to handle the stresses of the elements and stand the test of time.
  • A storied history – We’ve been around for 50 years. Plenty of time to watch the industry evolve in a number of ways. We’ve been around for all of the trends and know the importance of adapting to stay on the cutting edge. Our experience gives us a leg up, and our willingness to keep things fresh ensures that our products remain at the fore.
  • Unbeatable selection – The S-Model is among our most popular buildings, but it’s not the only one. We offer a range of choices to fit many different needs.

Do you think the S-Model would make a nice addition to your operations? Or perhaps you’re intrigued by our steel building concepts, but would like to explore a bit further? Either way, give us a call to learn more about our prefabricated structures and how you can best make use of services.

What Our Customers Say

We've helped thousands of customers nationwide and are ready to help you!

My New Business

"I always wanted my own business but renting a workspace wasn't cost efficient. The space I was looking at was more than $1,000 a week! So on a whim I decided to give American Steel Span a call. They mentioned to me about some specials they might be able to save me money on. I ended buying a steel building for what I would've spent on two months renting! Now I own my own that I work out of. Thanks to American Steel Span I have saved thousands of dollars and my business is flourishing, I even have employees!"
- Jeff Z - New York

Up in One Day!

"The delivery truck came on Saturday morning. By Sunday dinner we had our brand new two car garage. It was simple and easy to build - even fun! That was 10+ years ago and it still looks the same. Everyday I look at the building with real pride. Thank you American Steel Span."
