Weaknesses intensify propaganda in recent years, in the world several times the destructive power of a great earthquake occurred, so that the most important advantage of steel construction - seismic performance - stand out. However, a problem can not be avoided, steel residential construction costs are indeed higher than the concrete building. From the actual situation in China, the promotion of post-disaster reconstruction in steel residential recovery of the local economy is no large concrete building of the pulling power of steel products, because steel factory production of steel housing is installed, assembled at the construction site, you can save a lot workforce. In addition, for the building, as long as the country can achieve the release of seismic standards is safe, not because of the occurrence of the "5.12" Wenchuan earthquake, we put the building seismic standards too high, you want to build for our country conditions of residence. Japan, the United States of seismic standards of buildings higher than ours, which is determined by the state power. On the other hand is not because steel compression resistance, tensile strength is very good, an earthquake and other natural disasters; Japan, the US steel residential occupancy is relatively high, partly because they have strong economic strength produce brittle fracture of steel, and concrete structure will produce brittle fracture, and can not be reused. Steel residential important reason is not yet universal in our country is that people know little about. People do not care whether the steel residential industrial production, they are more concerned about building safety and comfort. Many people do not come into contact with steel housing, coupled with propaganda is not, leading them to believe that steel residential home uncomfortable. Residential Glass promote the slow and cost. It is understood, LOW-E glass and ordinary glass whiteboard higher than the cost of about 200 yuan / square meter, but because also supporting LOW-E glass and aluminum doors and windows adaptation, probably higher costs 200-300 yuan / square meter . However, Li Fan, said he had done the calculation, in equal shares to the utility area, the use of energy-saving glass of real estate costs rose 20 yuan / square meter, "not a big expense." On the other hand, buyers are also energy-saving ideas to be universal. Insiders said: "Today's buyers do not care whether the energy saving, buyers care about is the price, real estate location, facilities, which also makes the developers do not want to invest in energy efficiency." The industry believes that energy-saving glass in order to get rapid promotion in the house, but also administrative support. "Sales of residential glass is actually directly facing the real estate company, this one is actually very good control." "Now the government has policies in Hangzhou." Mr. Qian Xixi company, said steel maintenance, "in Ningbo, there are some high-end real estate use We believe that this market will grow rapidly. "And said Li Fan, building energy-saving glass in recent years, growth will be more than 30%. It is understood that China's Low-E glass usage in buildings less than 10%, while energy-saving glass penetration of American and European countries is as high as 85%. Policy support, but also the glass industry leading business expansion reasons. Although the Ministry believes the glass industry overcapacity, to eliminate backward production capacity, inhibit new capacity, but also made the top 10 large glass companies industrial concentration of 70% of the target three years.
