Corrosion resistance performance
Because our country is a large country, and building materials need to meet the requirements of all regions, all kinds of environment. Reference standards issued by the state, or special buildings for high corrosive region, galvanized quantity shall be not less than 275 g / ㎡ (double) or aluminum zinc plated 150 g / ㎡ (double), and shall meet the provisions of the existing national or industry standards. This provision in accordance with the provisions of the Australian.
According to Australian research and development center of bluescope steel research data analysis, chongqing steel structure company galvanized steel plate and aluminium zinc steel plate used as structure and exposed to the external architectural coating consumption can make a big difference. Even within the same building, because of the construction parts sealing effect each are not identical, atmospheric corrosion environment caused by inconsistent. Because there are aluminum and zinc aluminum plating zinc coating on the surface of the two materials, aluminum is more easy to corrode, extremely dense AL2O3, the aluminum oxide covered in steel plate surface, better cut off from the coated steel corrosion environment of contact with the outside world. Therefore aluminum zinc plating layer in the indoor environment prediction life far longer than we require that the structure of the life, can reach more than 200; Even in ventilation between the board that the environment is very bad, predict life can reach 75.
Saving energy and reducing consumption performance
According to the light steel structure housing and the performance of the traditional housing form of saving energy and reducing consumption, chongqing steel structure company can clearly see the advantages of light steel structure housing. Technical and economic indicators mainly by the coefficient of thermal conductivity of building structure, the heat storage coefficient and daily energy consumption per square meter to evaluate. According to the light steel structure housing and the traditional steel structure housing the contrast experiment, the traditional coefficient of thermal conductivity of the steel structure housing between 0.065 ~ 0.08 W/m k, the coefficient of thermal conductivity of light steel structure housing between 0.055 ~ 0.07, the coefficient of thermal conductivity of light steel structure housing than the traditional steel structure residential decreased 0.01 W/m, k; Traditional steel structure residential heat storage coefficient between 0.95 ~ 1.10 w/m.k, light steel structure residential heat storage coefficient between 1.30 ~ 1.40 w/m k, light steel structure housing than traditional heat storage coefficient of the steel structure housing decreased 0.3 w/m. k.
At the same time, because of the light steel structure system of the weight is light and flexible structure, on the basis of meet the requirements of structural strength, is able to integrate all kinds of heat preservation and heat insulation technology, in addition to the wall of the wall between column filled with glass fiber, also used to put a layer of heat preservation on the outside of the wall material of "exterior insulation" approach, the effective partition by wall column to the outer wall heat bridge; Fill glass fiber between floor floor beam, minimize heat transfer through the floor; All interior wall posts are filled between the glass fiber, reduce the heat transfer between the household wall.
