In recent years, remarkable achievements have been made in the development of building steel structure in China. At present, the use of steel structure is one of the structures with the least impact on the urban environment, with energy saving, environmental protection, light weight, easy installation, high safety performance comprehensive advantages.

1. The design adopts steel structure design, with great flexibility, high difficulty, large span and special shape.

2. Due to the reduced dead weight, the amount of soil taken by foundation construction is small, and the damage to this precious land resource is also small.

3. When the service life of the building expires, the solid waste generated by the demolition of the steel structure workshop is less, and the recycling price of scrap resources is high.

4. The calculated steel structure workshop is accurate, because the steel structure is uniform in quality and strength, which can not be reached by other materials.

5. The strength, toughness and safety of high toughness steel structures can be improved by proper composition mixing and heat treatment.

6. Greatly reducing the use of concrete and bricks, reducing the excavation of mountains and rocks around the city, which is conducive to environmental protection.

7. High degree of industrialization and fast construction are conducive to the realization of industrial production; Non-combustible, non-combustion-supporting, good fire performance, etc.

8. Light steel structure covers a small area, which actually increases the use area, use value and economic benefits of the building.
