Prefabricated steel structure buildings feature high fire resistance and strong anti-corrosion capabilities. The steel structure warehouse primarily consists of main bearing steel components including steel columns, beams, roof trusses, and all connecting parts through welding, bolting, or riveting.

The roof and wall panels can be made from composite panels or single sheets. Galvanized metal panels prevent rust and corrosion, while self-drilling bolts ensure tight connections and prevent leakage. Various composite infill panel options are available including polystyrene, glass fiber, rock wool, and polyurethane sandwich panels.

Steel structure walls can also be supported by brick walls. These structures are suitable for large plants, warehouses, supermarkets, entertainment centers, and modular steel garages.
