What Our Customers Say

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."
