The Feasibility Analysis & Policies Choice Of Promoting Light Steel Building In Chongqing

Foreign research and practice show that the light steel housing system is an excellent system, with light density, fine heat insulation function, high space utilization ratio, tiny environmental pollution, and high recovery coefficient. At present, this structure is being used in villa, in some of the developed city of coastal provinces. In the background of urbanization accelerating and building economical society in Chongqing, the housing industry is being required to provide adequate houses, which are eligible. However, the exiting housing construction mode is far from the exigent housing demand bringing by urbanization and economy development. At the same time, the conflict between economy development and environment pollution become more and more serious. It has become a stumbling block in the path of economy development in Chongqing. Building economical society has been brought up to the primacy in the government command paper.The light steel housing system can easily be built in a industrial mode. The parts can be prefabricated in the factory, avoiding the inflection of bad weather, landform and so on. So the inferior rate can be reduced and the productivity can be improved. Meanwhile, new construction material and equipments, which is much environmental friendly, can easily be integrated in the system. Therefore, developing the light steel housing system meet the demand of urbanization and building economical society. It can certainly become an important embranchment in housing industrialization. Since there is no light steel housing system in Chongqing real estate market, and no experience can be use for reference, we should study the technical feasibility and market feasibility. Chongqing is the youngest municipality in China, also the only municipality in the western part of China. Promoting the light steel housing system in Chongqing is provided with a series of advantages. For example, the sustaining developing economy, the accelerating urbanization, the wise government, the healthily developing real estate market, and so on.Although compare with the conventional concrete structure system, the light steel housing system have many advantages in heat insulation and saving energy, but it doesn't advantaged in fireproofing, sound insulation, antisepsis and so on. It should recur to the assistant material, which can increase the building cost. The weather in Chongqing is very diagusting, with hot summer, cold winter, and heavy humidity, heavy acidic gas. These all bring forward challenge to the light steel housing system.At the same time, the challenge also comes from the marketing aspect. The geology situation in Chongqing is better than what in the coastal areas. Manpower cost is also relatively cheap. So the advantages of the light steel housing system are difficult to show up. Second, the light steel housing system has no advantage in fireproofing, sound insulation, and antisepsis and so on. It should recur to the assistant material, which can increase the building cost. Third, though the light steel housing system has advantages in using phase, but the original investment is often higher than the conventional concrete structure system. The consumers refuse to buy this kind of house, and the developers are also cautious to this kind of house.Technological artifice is being using to resolve the technology problem. After the one-year's investigation, the author sees that the technique is already mature. While the marketing problem needs integrated effort. We should form a well-off circle between the government, the developer, and the consumer, under the guidance and interfere of the government. We hope the light steel housing system can abloom and bear fruit in Chongqing, and bring benefits to the Chongqing People.
