Product Description
Our steel structure buildings offer exceptional fire resistance and strong corrosion protection. The primary load-bearing components consist of steel columns, beams, and roof trusses, connected through welding, bolting, or riveting.
The roof and wall systems can be constructed using composite panels or veneer. Galvanized sheet metal provides rust and corrosion prevention, while self-tapping screws ensure tight connections to prevent leakage. Composite panel options include PU, EPS, fiberglass, or rock wool cores for superior thermal insulation and fire resistance. Brick walls can also be incorporated into the steel structure design.
