"We are left to future generations of wealth or junk? If you do not want to overdraw the future, then start from the building, built from steel housing as the starting point." Recently, held in 2013 in Chongqing steel industry at the annual meeting, the experts called Steel promote the housing industry.

Today, with the new fiber cement boards and steel in six months time will be able to build a high-rise anti-8 earthquake.

China's annual construction waste up to 400 million tons, has accounted for 40% of total municipal waste, not only caused a great waste of social resources, the environment for human survival but also pose a huge threat.

How to reduce construction waste? Chinese Academy of Engineering Ma Kejian that steel minimal impact on the urban environment is one of the building structure.

Ma Kejian said steel housing industry, simply put, is to load-bearing steel structural member of the skeleton to light construction materials for the building envelope wall.

In other words, the future Gailou the materials used are mainly steel, more than 80% of these materials are designed at the factory. Construction of buildings, just put a steel frame with screws embedded together like building blocks as simple: a 30 multi-story buildings, built from the foundation to the excavation, not half a year to complete. Meanwhile, 70% of recyclable materials and reduce construction waste 2/3.

Moreover, the construction process is to achieve a low-carbon, green: the construction area, noise, field water and electricity were reduced by more than half the construction period can be shortened by 30% -50%. Meanwhile, steel, high strength, light weight, has a good seismic performance characteristics. Especially when compared with the traditional residential, architectural space can be increased using the area of ​​4% -8%.

Zhejiang, China Steel Association Fang Hongjiang, for steel residential construction process of industrialization summarizes the six advantages: First, the factory site to do things, two things that are outdoors indoors, three high-altitude ground things to do, four are dangerous machine to do complex things, five is the construction simulation and field stakeout computer to do things, six is ​​a waste of resources and do not pollute the environment.

Such as wall decoration, is a dangerous thing, steel housing industry usually steel glass curtain wall approach can be completed at the factory. Site, workers can simply install. Demolition of buildings is also very simple, without blasting, workers simply remove the screws come on the line.

According to reports, in Japan, the U.S., France, steel housing has accounted for 40% of all the residential units, China is less than 2%. Currently China Steel housing industry in its infancy, technical problems hampered its application, steel residential one-time investment is higher, compared to 15% higher cost of ordinary housing, housing maintenance of the structure, floor attachment process is complex and technically demanding. From the developer perspective, on the use of new technologies such as low-carbon energy enthusiasm is not high.

According to the introduction, in 2011, the first time the national green building written "second five" plan to encourage the steel used for the protection of housing construction, Chinese steel industry ushered in the spring.
