Quick Details 1.With Clearspan, the hangar provides a great large space for the plane. 2.Cost efficent and energy efficient are the important factors of pre-engineered aircraft hangars 3.All structural steel members are made from Q345B or ASTM A572 Grade 50 structural steels. Specification Besides meeting the building codes, steel construction codes, we will try our best to design and fabricate the pre-engineered aircraft hangars less cost and saving energy. Customers' needs, enviromental factors(such as seismic zone, rain load, snow load, wind load, etc.), land size are the major factors, which our engineers and designers considerate. We have several building spans for your option, you can choose one according to the size of the aircraft hangar Type Sketch Size Straight Column Steel Building Frame,Clean Span Width: 16' to 150' and over Height: 8' to 60' and over Standard roof slope: 1/2:12 to 1:12 Tapered Column Steel Building Frame,Clear Span, Width: 30' to 300' and over Height: 10' to 60' and over Standard roof slope: 1/2:12 to 2:12
