Pre Engineered Steel Structure Warehouse Buildings Light Steel Structure
Steel structure factory building, safety and mechanization degree is high.
The materials used in steel components are single, and they are finished products, with simple processing, high degree of mechanization and short construction cycle.
Steel structure plant weight is light, although the steel ratio is significant, but its mechanical properties are very good, can withstand large load, steel structure section size is small, the same load, the weight of steel roof truss but reinforced concrete truss 1/3 or 1/4.
The steel structure is light in weight and easy to transport.
The steel structure standard workshop has flexible layout and high utilization rate of building area.
The flexible and changeable workshop process layout requirements and limited space utilization ratio of steel structure workshop can also well solve the ventilation, lighting, heat insulation and roof drainage, living facilities layout, personnel evacuation and so on.
