Currently, the technology rather than fragmented systems, varying skill levels and standards, not plete, but needs further research and innovation and integration. In addition, building materials and parts, the current pilot project will require the construction of light steel structure in many materials shipped from abroad, and even some foreign investors in mainland China, missioned by the processing of parts, often can only go abroad to purchase, in the domestic market Can not find a time. This also restricts the development and promotion of domestic steel. Lack of professional and technical personnel In terms of personnel, the domestic secondary or higher professional schools, regardless of the teaching contents are less involved in light steel structure house, so my architectural professional engineers know little about this system, but more the lack of a skilled workers, so although the system is not purely a technical level, how much difficulty, but the real lack of effective implementation of them is often the backbone. Cost issues Light steel structure housing the current offer in the mainland of China is about the traditional concrete structure with conditions times residential, domestic consumers in the near term unacceptable. However, this price structure in foreign countries other than the cost of housing is, it is highly petitive, which is why the light steel structure house abroad, the reason can flourish. Any new technology and the emergence and development of both technical and economic context in which society is linked, adapt, and now the United States, Japan, Europe and other developed countries and regions, China39。s accession to WTO since many foreign domestic manufacturers were seeking to enter the China market, but they did not know that their Laidao China What qualifications should apply for after, are in what capacity Design unit? Construction unit? Integrators? Or the manufacturer? 4 Prospect Steel Residential Calculated according to the lowest level in developed countries, China39。s of last century, the State Ministry of Construction and the State Economic and Trade Commission unanimously adopted the universal system of light steel structure residential building development and application as the breakthrough point of the steel construction industry in China, and officially listed as national key technical innovation projects. The initiative for the development of China39。s housing industry, which will be promoting the economic development of new growth. Steel housing is easy to implement industrial production, standardized production, but with the wall material can be matched with energy saving, environmental protection, new materials, which are green environmental protection building, renewable reuse, consistent with sustainable development strategies, therefore Complete steel structure system technology research house will greatly facilitate the rapid development of housing industry, a direct impact on the development level of China39。s macrocontrol function, housing an
