Q355 Prefabricated Steel Structure Warehouse with 50-Year Lifespan

Q355 Mechanical Warehouse Prefabricated Steel Structure Building

Q355 Mechanical Warehouse Prefabricated Steel Structure Building that is used to process sandwich panel. It has three spans. Each span has one 5T overhead crane. The main steel frame structure is consisted of Welded H-shaped steel beam & columns. The roof and wall panel are Rock wool sandwich panel.

Prefabricated Steel Structure Building is widely used as large warehouse, factory, workshops, sheds, garage, hangar, office buildings, bridges, stadiums and other buildings. Portal frame steel structure building is a new type of building structure system, which is formed by the main steel framework linking up H-section, Z-section, and U-section steel components, roof and walls using a variety of panels and other components such as windows and doors. We have special steel structure engineering design department and R & D department, Established an independent and perfect steel structure engineering design, optimization and deepening design system. Establishing engineering material-to-material storage, we not only control the reliability and economy of the structure, but also the types, performance, selection and combination of traditional enclosure materials and new maintenance materials. Our design is not only more applicable, safer and more economical, but also richer in architectural art.
