China's steel structure explores the international market

The steel structure is very large, especially the steel structure green building system, which will break the boundary between real estate, construction, machinery and equipment manufacturing, green building, new building materials, disaster prevention and mitigation, home appliance kitchen decoration and other industries, and become a new one. The circular industrialization industrial system; the real estate industry funds can be returned to the modern economy and other real economy to achieve economic transformation and upgrading. In the long run, it is an emerging industry of national strategic resource reserves, which can hide steel in architecture, conserve wealth and benefit the people and benefit generations. Therefore, in recent years, China's steel structure and residential buildings are continuing to develop. According to preliminary statistics, Beijing, Tianjin, Shanghai, Zhejiang, Hubei, Inner Mongolia and other provinces and cities have developed or built more than 10 million square meters of steel structure houses. A large number of steel structure buildings with world-class levels, such as the Water Cube, CCTV New Office Building and Shanghai Global Center, have become the application model projects for the construction of steel structures in China. Therefore, the steel used in the steel structure manufacturing industry is large in quantity, high in quality, and has many varieties. There are Pu steel, excellent steel, and special steel. Among them, U-steel accounts for a large proportion, especially low-alloy high-strength steel, weather-resistant steel, fire-resistant steel, ultra-high-strength bolts, high-performance color-coated steel plates, high-grade alloy plates, etc., and its demand is increasing. Recently, the National Development and Reform Commission and the Ministry of Housing and Urban-Rural Development proposed to build 1 billion square meters of green buildings during the 12th Five-Year Plan period. By the end of 2015, 20% of new urban construction projects have met the requirements of green building standards. Among them, steel structure is becoming one of the development directions of green buildings. The Ministry of Housing and Urban-Rural Development's “Twelfth Five-Year Development Plan for Construction Industry” requires that the energy consumption per unit of added value of construction products during construction during the 12th Five-Year Plan period will be reduced by 10%, and the amount of concrete above C60 will reach 10% of total consumption. A total of 45% was used, and the proportion of steel structure engineering increased. In this regard, some analysts predict that by the end of the 12th Five-Year Plan, China's steel structure output will reach 50 million to 65 million tons, and the overall industry outlook is optimistic. According to this goal, iron and steel enterprises should further improve the quality of steel for steel structure, increase the development and application of varieties, increase the variety of structural high-performance steel and connecting materials, and expand the production of economical profiles such as thin-walled H-beams. Improve the products and application scales of steel products for building structures; promote the application of steels such as weathering steel, fire-resistant steel and color-coated plates; develop ultra-high-strength bolts, high-performance color-coated steel plates, high-grade alloy plates, etc., and strive for China's steel structure The steel used in construction is basically localized. Industry insiders remind steel companies that with the increasing emphasis on environmental protection, green and energy-efficient buildings will become the focus of future urban construction. Driven by the urbanization construction, the market size of green steel structure buildings will be very large, and it is expected that a huge market of over one trillion yuan is accelerating. For steel companies, changing the concept and entering the steel structure industry is a new way to achieve transformation and development. Both the government and steel companies should pay more attention to the steel structure industry.
