Compared with structures made of other materials, steel structures have the following characteristics:

1、 Although the bulk density of light steel structures is relatively large, their strength is much higher compared to other building materials. Therefore, when subjected to the same load and conditions, steel structures are lighter than other structures, easier to transport and install, and can span larger spans.

2、 Steel has good plasticity and toughness, which ensures that steel structures generally do not suddenly fracture or fail due to accidental or local overloading. Good toughness makes the steel structure more adaptable to dynamic loads. These properties of steel provide sufficient assurance for the safety and reliability of steel structures

3、 Steel is closer to homogeneous and isotropic materials, and its internal structure is relatively uniform, very close to homogeneous and isotropic materials. It is almost completely elastic within a certain stress amplitude. These properties are consistent with the assumptions in mechanical calculations, so the calculation results of steel structures are more in line with the actual stress conditions.

4、 The steel structure is easy to manufacture, suitable for industrial production, and has a short construction and installation period. The steel structure is composed of various profiles and is easy to produce. A large number of steel structures are manufactured in specialized metal structure manufacturing plants; *High degree. The manufactured components are transported to the site for assembly, connected by bolts, and have a lightweight structure, making construction convenient and with a short construction period. In addition, the existing steel structures are also easy to dismantle, reinforce, or modify.  

5、 The steel structure has good sealing and water tightness.  

6、 Steel structures have good heat resistance, but poor fire resistance. Steel is heat-resistant but not resistant to high temperatures. As the temperature increases, the strength decreases. When there is radiant heat around and the temperature is above 150 degrees, shading measures should be taken. If a fire occurs and the structural temperature exceeds 500 degrees, it may all collapse instantly. In order to improve the fire resistance rating of steel structures, they are usually wrapped in concrete or bricks.

7、 Steel is prone to rusting and protective measures should be taken. Steel is prone to rusting in humid environments, especially in environments with corrosive media, and must be coated or galvanized. In addition, regular maintenance should be carried out during use. Compared with other structures, steel structures have advantages in terms of functionality, design, construction, and comprehensive economy. The advantages of using steel structures in residential buildings are mainly reflected in the following aspects: Firstly, steel structure residential buildings can better meet the requirements of flexible separation of large spaces in buildings, and can improve the area utilization rate by reducing the cross-sectional area of columns and using lightweight wall panels, increasing the effective indoor use area by about 6%. 2、 Good energy-saving effect, the wall adopts lightweight energy-saving standardized prefabricated wall panels instead of clay bricks, with good insulation performance, saving 50% energy, and saving heating and cooling costs of 18 yuan per square meter per household. 3、 The use of steel structure systems in residential buildings can fully utilize the good ductility and strong plastic deformation capacity of steel structures, which have excellent seismic and wind resistance performance, greatly improving the safety and reliability of residential buildings. Especially in the event of earthquakes or typhoons, it can prevent the collapse and damage of buildings. In the 1995 Hanshin earthquake in Japan and the 1999 Taiwan earthquake, almost all of the steel structures that did not collapse were made of H-beams. 4、 The total weight of the building is light, and the self weight of the steel structure residential system is light, 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 shortened by at least one-third compared to traditional residential systems, thus reducing the overall cost by 5%. Accelerate capital turnover and greatly improve investment efficiency. 6、 Good environmental protection effect. During the construction of steel structure residential buildings, the amount of sand, stone, and ash is greatly reduced. The materials used are mainly green, recyclable, or biodegradable. When the building is demolished, most of the materials can be recycled or degraded, and will not cause a lot of garbage. 7、 Has a high cost performance ratio.

8、 The architectural style is flexible and rich. Large open room design, indoor space can be divided into multiple schemes to meet the different needs of users. 9、 Meet the requirements of residential industrialization and sustainable development. Steel structures are suitable for large-scale production in factories, with a high degree of industrialization, and can integrate advanced products such as energy saving, waterproofing, insulation, doors and windows into a complete set of applications, integrating design, production, and construction, and improving the level of the residential industry. In summary, steel structure is a suitable innovative residential structural system. Steel structures can be designed in various shapes, scales, and spaces according to people's different aesthetic preferences and functional requirements. Manufacturers can achieve high-precision, high-quality, and high-speed completion, making buildings both aesthetically pleasing and economical.
