Wind Resistance: steel structure building light weight, high strength, overall rigidity, strong anti-deformation ability. The self-weight of the building is only one-fifth of that of the brick--mortar structure, which can withstand a hurricane at 70 meters per second  effectively protect life  property. Durability: the light steel residential structure is entirely composed of cold-formed thin-walled steel members,  the steel bones are made of super-anticorrosive Gao Qiang cold-rolled galvanized sheet, which can effectively avoid the corrosion of the steel plate during construction  use, the service life of light steel members is increased. The life of the structure can reach 100 years. Thermal insulation: the use of thermal insulation materials to glass fiber cotton-based, with good thermal insulation effect. With the external wall of the insulation board, effectively avoid the wall of the“Cold bridge” phenomenon, to achieve a better insulation effect. The thermal resistance of R15 insulation cotton about 100mm thick can be equal to that of brick wall about 1m thick. Seismic resistance: most of the roofs of low-rise villas are pitched roofs, so the roof structure is basically a triangular roof truss system made of cold-formed steel members, formed a very strong“Plate ribbed structure system”, this structure system has a stronger seismic  resistance to horizontal load, suitable for seismic intensity of 8 degrees above the region. Sound insulation: sound insulation is an important indicator of residential evaluation, light steel system installed windows are insulating glass, sound insulation effect is good, sound insulation of more than 40 decibels; By the light steel keel, heat preservation material gypsum board composed of the wall, the sound insulation effect can be as high as 60 decibels.
