Prefabricated Steel Structures Commercial Buildings
Compared with traditional concrete buildings, steel structure commercial buildings are quick-install structures. The framework consists of steel columns, beams, trusses, bracing, purlins, U channels, angle steel, and steel plates, connected by welding, bolts, and rivets.
The steel frame includes vertical columns and horizontal beams bolted or welded together. Columns transfer compressive loads to form the building skeleton, while beams resist lateral loads. All components are factory-manufactured with precision (tolerance <2mm) following international standards (GB, IS).
