With the development of science and technology as well as continuous renovation in people's ideas, light steel structure is widely used in build houses,villas, office buildings and business mansions. It has become a new choice of people. The light steel structure has the following advantages compared with traditionalbuilding styles: 1) Durability: the light steel structure frame consists of studs rolled from antisepsisgalvanized steel plate, and it effectively avoids corrosion of the wholeframe in the process of use and hence improves the service life of residence toa great extent2) Shockresistance: the house consists of a triangle structure made from C steelstud as well as wall stud. After the structure plate and plasterboard is sealed,the solid "plate rib structure system" is hence formed. This structure boasts strongcapacity of shockresistance and level loading resistance. It can be appliedin areas which may be hit by an eight magnitude earthquake 3) Wind-and-snow-resistance: the light steel structure is quite light but strongin intension. With excellent form, it can resist snowstorm. The weight of the buildingmade of light steel structure is just one fifth that of brick and concretestructure. Therefore, the light steel structure can resist the wind at a speedof 50m/s 4) Bug-and-termite-resistance: the light steel structure adopts galvanized steelproducts, without crude wood. It can avoid invasion of termite and other bugs. It not only improves the service life of houses but also reduces maintenance costborder=0>border=0> producing area:China payment:T/T, L/C supplying capacity:300MT/month
