Structure or technology or, finally to be implemented in the use of functions, let the old common people visible, tangible, lived contentedly. Reinforced concrete is still the main material of Chinese architecture, in some areas even see brick and concrete building. Japan, the US steel housing, according to a relatively high rate, partly because they have strong economic strength; on the other hand is due to compression of the steel structure, good tensile strength, earthquake or other natural disaster hit when not will produce brittle fracture, while the concrete structure will produce brittle fracture, and can not be reused. Indeed install steel structures for construction services, the use of the function is the construction of most concern to consumers. To promote the steel construction, it is necessary to improve the use of steel construction features, can not let the steel structure housing the impression is cold. Old common people do not care whether the steel housing for industrial production, they are more concerned with building security and quiet nature. From the actual situation in China, the promotion of post-disaster reconstruction in steel residential recovery of the local economy is no pulling power of large concrete building, due to the steel housing is factory produced, assembled at the construction site of steel construction, you can save a lot of labor. A lot of the old common people have not been exposed steel structure, coupled with propaganda is not steel, steel residential home cause they think is not comfortable. Some steel housing demonstration projects all around the building structure to work on, this is wrong. Japan, the United States, building seismic scale higher than ours, which is determined by the state power. Steel construction makes the most important strengths - good seismic performance - stand out. In Japan, the United States and other Western countries, the total residential steel buildings as high as 50%, while China's steel housing is still in the pilot stage of promotion. Steel construction, steel Zhongshan, Peng Jian Steel Co., Ltd., Dongguan City, Peng was built by steel.
