Furthermore, governments vigorously promote the construction in ecological civilization that pays highly attention in steel structure industry, The effect of high temperature insulation wool board is improved , the sale of the prefabricated workshop supplier building materials market due to uneven density rock wool insulation vulnerabilities easily prefabricated warehouse formed , By doing so, it can guarantee heat in indoor would not be absorbed or leaked by walls, The wall thickness is small, the line can agricultural steel buildings be steel structure workshop building dark buried in the wall and floor structure, building interior actually use the area is increased, increase by at least 15% than traditional masonry structure house, if the same construction area of brick structure and light steel structure housing, it is not difficult to find the actual usable floor area of light steel structure housing and the cost of single brick structure of the cost of the same, From the macro perspective, the national development strategy has been put forward clearly that to improve and strengthen social construction of people’s livelihood and innovation management, developing a strong socialist culture in China, Architectural steel can be divided into steel structural steel and concrete structural steel, From the micro perspective, steel structure makes full uses of modern materials, manufacturing and construction technology, presenting the modern design, the sense of science and technology, showing the high level of steel structure manufacturing and installation. The seismic performance is good, can resist 8 degree earthquake, suitable for coastal and the seismological area construction, At the same time, steel structure is getter closer to people’s life, while people get to know more about steel structure that it brings a lot of convenience in our daily life. Since the rapid development occurred in warehouse steel structure the previous 20 years, steel structure prefabricated building construction blossoms everywhere and large and small steel enterprises have more than 10,000,
