Product Description
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. Each component is 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. Self-tapping screws make connections between plates more secure to prevent leakage. Composite panels with PU, EPS, fiberglass, 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.
