Modern Bridge/Factory/Warehouse/Shopping Mall Engineering Construction Steel Structure
Steel structure building has features of high fire resistance, strong corrosion resistance. Steel structure building is mainly refers to the main bearing component is composed of steel. Including the steel columns, steel beam, steel structure, steel roof truss.Each component using welds, bolts or rivets to connect.
The roof and wall can be made of composite panel or veneer. Galvanized sheet metal can prevent rust and corrosion. The use of self-tapping screw can make the connection between the plates more closely, to prevent leakage. You can also use composite panel for roof and wall. The sandwich is PU,EPS,fiber glass, rock wool. They have good thermal insulation, heat insulation, fire-retardant. The wall of the steel structure maintenance also can use brick wall.
The usage scale includes large-scale workshop, or warehouse, supermarkets, entertainment centers and modular steel structure garage.
