How about the development of steel structure?

In industrialized countries, such as the United States, Japan and Britain. Steel structure housing is more popular, accounting for more than 40% of the housing market share, and has also formed a considerable industrial steel structure housing system; However, the proportion of steel structure houses in China is less than 1%. Steel structure building has the advantages of high strength, light weight, good seismic performance, low foundation cost, large building area, high building quality, suitable for industrialized and standardized production, unaffected by construction season and low comprehensive cost, and is called the representative of green building. Forward-looking Industry Research Institute believes that in recent years, the state has successively issued policies, such as the Twelfth Five-Year Plan for the Development of Construction Industry and the Guiding Opinions on Resolving the contradiction of serious overcapacity, all of which point out that it is necessary to increase the proportion of steel structures used in the construction field and vigorously develop green buildings. At the same time, the scale of real estate investment and the construction area of commercial housing maintained rapid growth. This has a positive impact on the development of steel structure industry in China. From June 2065438 to October 2003 10, the national commercial housing sales area was 9593 1 10,000 square meters. If 5% of them are steel structures, the demand for steel structures will be around 24 million tons, which is a huge market. In the future, with the continuous growth of China's real estate investment, the proportion of steel structure used in residential buildings is increasing, and the expansion of steel structure market demand is very considerable.
