All Simpson commercial steel buildings are custom designed per your layout. Typically this category works best with the rigid frame design. The wider spans and taller structures lend themselves to the rigid frame. With spans up to and beyond 200 ft. the rigid frame serves the industry well when designing commercial steel buildings. Our base commercial steel buildings are designed to withstand a 20 pound snow load and 80 mile per hour winds, additional loading is available by strengthening our framework. Commercial steel buildings can be designed to set on a variety of foundation conditions. Panels are cut to length requiring very little field cutting before assembling to these commercial steel buildings.
