Product Description
Our steel structure buildings feature high fire resistance and strong corrosion resistance. The primary load-bearing components are constructed from steel, including columns, beams, and roof trusses, connected through welding, bolts, or rivets.
Roof and wall options include composite panels or veneers. 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, heat resistance, and fire-retardant properties. Brick walls are also available for structural maintenance.
