Powerbilt steel arch buildings were the first of their kind to receive Government Services Administration (GS07F0319K) approval. We have satisfied requirements for all branches of the US armed services including: the Air Force, Army, Coast Guard, Marines and Navy as well as designing buildings for the Federal Prison System. All Powerbilt metal buildings are shipped with an easy to follow assembly manual and can be erected with as few as four people in as little as three days. Over 70% of the simple bolt-together construction is done on the ground and requires no special tools or equipment. Most customers are able to erect their buildings themselves.Our buildings are 100% American made and manufactured in Pittsburgh, Pennsylvania from the highest quality US commercial steel available. They carry an American manufacturer’s warranty. Keep America strong buy American! Virtually maintenance-free, you will have no gutters to clean, siding to paint or shingles to replace. Our steel arch buildings are fire resistant and vermin proof.
