Q Model Steel Buildings are rugged, durable, and can be manufactured with clear span space from 20′ wide up to 100′ wide. This style building is reminiscent of the traditional quonset hut development during World War I. The structure is a rolling arch from ground connection to ground connection of the side walls which create both weather protection and structural stability and strength. This means no internal framing is necessary providing 100% usable space on the interior.
