Why steel structure, not concrete?

First :

The weight of the steel structure is light and the strength is high. The house weight constructed with steel structure is about 1/2 of the reinforced concrete house, and the use area is about 4% higher than that of the reinforced concrete house, and the foundation cost is low because of the self weight. Safety and reliability, good seismic and wind resistance, good structural performance.
The steel structure component is made in the factory, the quality is assured, the workload is reduced, the construction period is shortened, and the industrial requirement is met. Steel structure factory production quality is reliable, accurate size, easy installation, easy to cooperate with related parts.
Steel can be recycled, less pollution to the environment when building and dismantling, more energy saving and environmental protection than masonry and concrete. No wet operation on site, no dust and other pollution problems. 7, the structure of the structure is small, the wall is thin, so the area can be used relatively large.
