Prefabricated Light Steel Warehouse Building with H-Section Beams

Our steel structure buildings feature high fire resistance and strong corrosion resistance. The main bearing components are composed of steel, including steel columns, steel beams, and steel roof trusses, connected using welds, bolts, or rivets.

The roof and wall can be made of composite panel or veneer. Galvanized sheet metal prevents rust and corrosion, while self-tapping screws ensure tight connections between plates to prevent leakage. Composite panels with PU, EPS, fiber glass, or rock wool insulation provide excellent thermal insulation and fire-retardant properties. Brick walls can also be used for steel structure maintenance.

Applications include large-scale workshops, warehouses, supermarkets, entertainment centers, and modular steel structure garages.
