Because a small amount of field operations, the surrounding environmental pollution at the same time, construction of the high degree of mechanization, speed up the construction pace. According to statistics, the same area of the building, steel structure, concrete structure construction period can be shortened more than 1 / 3, and can save formwork materials. Integrated low cost As the light weight, lower cost basis, the overall material reduction in direct costs, short construction period, and reduce indirect costs, so an integrated low cost. meet the housing industry and the requirements of sustainable development Steel suitable for mass production factories, the high degree of industrialization, and is able energy saving, waterproof, heat insulation, doors, windows and other advanced product set in one, plete applications, will design, manufacture, construction and integration, improve the housing industry level. In addition, steel scrap would be achieved in 100% of waste recycled, so called steel building as a green building is not too much, it is to adapt our strategy of sustainable human development of new architectural forms. 3 steel residential development resistance (neck bottle) analysis Social acceptance Steel housing is the major problem facing the development of society as a whole to accept the new housing system needs a process. Light steel housing system is in a foreign country, especially in North America timber structure Jichu developed on which two kinds of system, while in foreign countries has been very matured and improved, but for our country is totally a new thing, Yinergezhong difficulties almost everywhere. As Chinese consumers have long used to the brick or reinforced concrete structure house, slowly began to receive progressively from light steel structure like residential, also requires a gradual process. rise steel technologies are not mature Complete steel structure system of residential technology, the past lack of technical guidance, market demand did not meet the level of industry, Thus, our functional singlerelated products, low level of industrialization, product quality can not meet the requirements of domestic industry Hua standards. 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 co
