Steel structure building is formed by the main framework through linking up the H beam, C purline, Z purline steel components. Roof and wall using a variety of panels together with other components such as windows and doors. The steel building has the advantages of wide span, high strength, light weight, low cost, temperature protection, save energy, beautiful appearance, short construction time, good effect of insulation, long using life, space-efficient, good seismic performance, flexible layout, etc.
1. Easy to assemble
The steel components arriving at the construction site are all prefabricated. During the construction process, the installation work needs to layout each structure and erect it according to the installation drawing.
2. Reasonable cost
The steel structure building is light in weight, reducing the basic cost, and the construction speed is fast. It can be completed and put into production as soon as possible. The overall economic benefits are much better than that of the concrete structure
3. Simple construction, short construction period
The production and installation of steel structure usually involve processing all required components in the factory and then transporting to the construction site to assemble. So the construction period is greatly shortened.
4. Energy-saving and environmentally friendly
The corrugated color steel sheet and sandwich panels used in the prefab steel structure workshop are all energy-saving materials. The steel structure also adopts dry construction during the construction process to avoid dust and environmental pollution caused by concrete construction
