Product Description
Our steel structure buildings feature high fire resistance and strong corrosion resistance. The main bearing components are composed of steel, including steel columns, beams, and roof trusses, connected using welds, bolts, or rivets.
The roof and walls can be made of composite panels 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, fiberglass, or rock wool cores provide excellent thermal insulation, heat 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.
