First, the construction cycle is short, the big advantage of lightweight steel structure is that all the components can be produced by the factory on-site splicing and installation, the general scale of the smaller industrial plants only 45 days to 2 months, and if the use of reinforced concrete buildings to 8 to 12 months or so.
Second, the overall economic benefits because the building itself is light, generally do not need to do piling, can save investment; due to the use of polystyrene foam sandwich panels or veneer plus thermal insulation cotton and other measures, so that thermal insulation, heat insulation and insulation chapter and other good results. According to the current market price in China, the cost of light steel structure has been lower than the reinforced concrete structure, when the larger the span of the plant, the advantage is more obvious, which is also a major advantage it relies on to compete.
Third, good seismic performance due to the steel structure is a flexible structure, light weight, and thus can effectively reduce the degree of seismic response and the impact of disasters, extremely conducive to earthquake resistance. Our country is a multi-seismic area countries, in the earthquake area should be more popular application of steel structure in the building, will greatly reduce the earthquake disaster and casualties. The painful lesson of the Tangshan earthquake should be remembered. At present, tianjin city has officially launched light steel structure housing.
Fourth, it is suitable for dismantling and relocation once the owner is not satisfied with the site or unexpected changes in the external environment, the whole building can be dismantled and relocated in a very short time, the loss is very small, and all of these are reinforced concrete buildings can not have. It is because of the many advantages of lightweight steel structure, and with the emergence of new products in recent years, fire prevention, anticorrosion, has been a better solution to the shortcomings of the lightweight steel structure of poor corrosion resistance, so that it is in the industrial plant as well as civil facilities to obtain a wide range of applications.
