Steel structure buildings offer high fire resistance and strong corrosion protection. The primary load-bearing components consist of steel columns, beams, and roof trusses, connected via welds, bolts, or rivets.
Roof and wall options include composite panels or veneer. Galvanized sheet metal prevents rust and corrosion, while self-tapping screws ensure tight connections to prevent leakage. Composite panels with PU, EPS, fiberglass, or rock wool cores provide excellent thermal insulation and fire resistance. Brick walls are also available for structural maintenance.
Ideal for large-scale workshops, warehouses, supermarkets, entertainment centers, and modular steel garages.
