Second, the market demand not achieve industrialization degree, related products functional single, industrialization level is not high, the product quality can not meet the standard requirement of housing industrialization.
Third, constructional steel is corrosive and fire resistance the demand is higher, the data shows, without any protection of ordinary steel once encounter corrosion and fire, 15 - and in the rain will soften. The United States and 9 middot; 11th, let people more focus on steel structure building fireproof performance.
Housing industrialization is the only way for the development of housing industry in China, and will become a new growth point to promote the economic development of our country. Although our country years steel production has up to 120 million t, but the steel products in construction steel structure of the proportion of use is less than 1%. Therefore, our country government proposed, by 2005 construction steel structure material to achieve the national steel production in 2010, from 3% to 5%. Ministry of construction and the relevant departments to set up a leading group for the construction steel, its main task is to promote in the building with the proportion of steel. At the same time, the ministry of construction steel structure housing has been included in the national key promotion project, Beijing, Shanghai, tianjin, etc, have built a batch of steel structure housing demonstration, pilot project. With the development of productive forces, people to the improvement of quality of life, the steel structure housing will be the country's focus on the development of object, in the future in the engineering construction on leading role.
