Foshan Steel plant seismic seismic intensity of 8 degrees or more, mostly low-rise villa roof sloping roof, so the roof structure is basically made ​​of cold-formed steel members triangular truss system, light steel structural components in the complete closure after the sheet metal and gypsum board, forming a very strong "plate rib structure system", this architecture has a stronger ability to resist horizontal seismic loads and for seismic intensity of 8 degrees above areas.
