1. Steel structure residences can better meet the requirements for flexible separation of large bays than traditional buildings. By reducing the cross-sectional area of columns and using lightweight wall panels, the area utilization rate can be increased, and the effective indoor use area can be increased by about 6 %.

2. The energy-saving effect is good. The walls are made of lightweight, energy-saving and standardized C-shaped steel, square steel, and sandwich panels. They have good thermal insulation performance and good earthquake resistance. 50% energy saving,

3. The use of steel structure systems in residential buildings can give full play to the good ductility and strong plastic deformation ability of the steel structure, and has excellent earthquake and wind resistance, which greatly improves the safety and reliability of the residence. Especially in the case of earthquakes and typhoons, steel structures can avoid collapse damage of buildings.

4. The total weight of the building is light, and the steel structure residential system is light in weight, about half of that 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 the traditional residential system. It only takes 20 days and five workers to complete a 1,000-square-meter building.

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

7. Be flexible and abundant. With a large bay design, the indoor space can be divided in multiple ways to meet the different needs of users.

8. Meet the requirements of residential industrialization and sustainable development. Steel structures are suitable for mass production in factories and have a high degree of industrialization. They can integrate advanced finished products such as energy saving, waterproofing, heat insulation, doors and windows, and apply them in complete sets, integrating design, production, and construction to improve the level of the construction industry.
