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

Materials can be found at your local building supply store.

2. Bolt Arches Together

Our precision-made arches fit perfectly and overlap to allow for fast and accurate assembly.

3. Raise the Arches Into Place

In most cases, no heavy equipment is required when raising your building.

4. Install the Endwalls and Doors

Our pre-cut, pre-drilled endwalls are easy to install and customized for your needs.

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!"

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."
