What our customers say
We hired National Steel Building and ProTrades to erect a 200x200 ft steel building addition to our facility, and the experience was outstanding. Their experienced crew had the entire structure unloaded, staged, and assembled in just 7 weeks, truly remarkable for a 40,000 sq ft free-span building. We are a DOD contractor that understands the value of perfection and NSB and ProTrades achieved it for us.
Sun SoldiersDOD contractor Google reviewThey did not pressure us but gave us the time and information to make informed decisions. They hit all their promised scheduling milestones: engineering, drawings, and delivery. We have now purchased another building from National Steel Building Corp. No extras, issues, or surprises. We will call them again.
Jeff AugeriRepeat customer Google reviewI purchased a 36x56 building from National Steel Buildings and I am very pleased. Brian helped me get my building designed and all the details along the way. He was prompt returning my calls and quick to respond with any questions or concerns. I would recommend Brian and National Steel Buildings.
Shawn Misner36x56 building Google reviewFrom the beginning they were honest, straightforward, and easy to work with. Communication was excellent throughout the entire process. It is refreshing to work with a company that does what they say they are going to do and genuinely cares about getting things done right.
