Multi-span huge steel structure workshop with mezzanine office room
Qingdao Huatuo steel structure workshop has features of high fire resistance, strong corrosion resistance. Steel structure workshop is mainly refers to the main bearing component is composed of steel. Including the steel columns, steel beam, steel structure, steel roof truss.
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. Composite panel for roof and wall can also be used in our system such as polystyrene, glass fiber, rock wool, polyurethane sandwich panel which have good thermal insulation, heat insulation, fire-retardant performace. 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.
