Green building refers to a building that can save resources, save land, water, materials, protect the environment and reduce pollution, provide healthy, efficient use and harmonious coexistence with nature in the whole life cycle of the building.In view of the deterioration of ecological environment and the shortage of resources and energy in China, “green buildings” have become popular in China.

 Steel structure building is a new type of building system, which can connect the industrial boundaries between real estate industry, construction industry and metallurgical industry, and form a new industrial system. This is the steel structure building system which is generally favored by industry insiders.Compared with traditional buildings, steel structure building has the following advantages: 1. Steel structure building can greatly save construction time, because the steel structure building module is completed in the factory flow production, the installation process is not affected by the season.2. For users, steel structure building can increase the use area of residential space, make people’s living more comfortable, reduce the emission of construction waste, and protect the ecological environment.3. With the collapse of old houses, there is no place to place construction waste, resulting in a waste of resources, and steel structure building materials can be reused, driving the development of other new building materials industry.4. Due to the good rigidity and deformation ability of steel structure, it is easy to transform, flexible and convenient in use, and brings comfort to people.

 Steel structure buildings appeared in Europe and the United States and other countries and regions very early. Due to the development of steel smelting technology in industry, the output and quality of steel are constantly improved and improved. The application of steel structure in Europe and the United States is growing rapidly. Industrial and civil buildings with steel structure appear one after another, not only in the number increasing,Moreover, the application scope is also expanding. The steel consumption of steel structure construction in the United States, Sweden, Japan and other countries has accounted for more than 30% of the steel production, and the steel structure construction area has accounted for more than 40% of the total building area.Many developed countries in the world attach great importance to the development of steel structure technology. The construction of super high-rise steel skyscrapers, large-span public buildings with beautiful shape and perfect functions and high-rise and large-span steel structure industrial workshops show their economic strength and modern construction technology level. The development level of steel structure buildings is a measure of the economic development of a country or region One of the important signs of Ping.In recent years, dozens of high-rise steel structure buildings have been built in Beijing, Shanghai, Shenzhen and other places, and large-scale single-layer or two or three-story light steel structure buildings have been built.With the expansion of the scale of building steel structure and the update of technology, the development history of steel structure ushered in the second spring.

 With the continuous introduction of China’s green building policy, the continuous improvement of the standard system, the deepening of the implementation of green building and the increasing national support for green building, when more people begin to pay attention to the quality of life, such as temperature, humidity and air quality, the promotion of green building will become a matter of pushing the boat, and the national new five-year plan puts forward the green building With more and more requirements and encouraging more green technology residences, China’s steel structure buildings will be displayed in front of people with rapid development posture in the next few years.
