                Durability: the residential structure of light steel structure is all composed of cold-formed thin-wall steel members, and the steel bones are made of super-anticorrosive high-strength cold-rolled galvanized steel plates, which can effectively avoid the influence of corrosion of steel plates during construction and use and increase the service life of light steel members. The structure can last up to 100 years.

                Heat preservation: the heat preservation and heat insulation material adopted is mainly glass fiber cotton, with good heat preservation and heat insulation effect. The thermal insulation board for the external wall can effectively avoid the "cold bridge" phenomenon of the wall and achieve better thermal insulation effect. About 100mm thick R15 insulation cotton thermal resistance value can be equivalent to 1m thick brick wall.

                Sound insulation: the sound insulation effect is an important index to evaluate the residence. The Windows installed in the light steel system are all made of insulating glass. The wall that by light steel keel, plasterboard of insulation material composition, its sound insulation effect can be as high as 60 decibels.
