Product Description
Our steel structure buildings feature high fire resistance and strong corrosion resistance. The main load-bearing components are made of steel, including steel columns, beams, and roof trusses, connected by welding, bolts, or rivets.
The roof and walls can be constructed with 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 insulation provide excellent thermal 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.
