1. Compared with traditional buildings, steel structure residential buildings can better meet the requirements of flexible separation of large bays in buildings, and can improve the area utilization rate by reducing the cross-sectional area of columns and using light wall panels, and the effective indoor area can be increased by about 6%.

2. The wall adopts light energy-saving standardized C-shaped steel, square steel and sandwich board, which has good thermal insulation performance and good seismic resistance. Energy saving 50%,

3. The steel structure system used in residential buildings can give full play to its good ductility, strong plastic deformation ability, excellent seismic and wind resistance performance, and greatly improve the safety and reliability of residential buildings. Especially in the case of earthquake and typhoon disasters, steel structure can avoid collapse damage of buildings.

4. The total weight of the building is light, and the self weight of the steel structure residential system is light, which is about half of the concrete structure, which can greatly reduce the foundation cost.

5. The construction speed is fast, and the construction period is at least one-third shorter than that of the traditional residential system. It takes only 20 days and five workers to complete a 1000 square meter building.

6. Good environmental protection effect. The amount of sand, stone and ash is greatly reduced in the construction of steel structure residence. The materials used are mainly green and 100% recycled or degraded. Most of the materials can be reused or degraded when the building is demolished, and will not cause garbage.

7. Flexible and substantial. Large bay design, indoor space can be divided by multiple schemes, which can meet the different needs of users.

8. In line with the requirements of housing industrialization and sustainable development. Steel structure is suitable for mass production in factories with high degree of industrialization. It can integrate advanced products such as energy saving, waterproof, heat insulation, doors and windows, and apply them in a complete set, integrating design, production and construction, so as to improve the level of construction industry.
