Steel structure villa system has been widely used for many years in Europe, Americaand many other countries. Small bridge is used as building component main body of the technical system. The bridge is composed of light thin-wall square pipe (or C-shaped and U-shaped pipes) manufactured by galvanized cold bending processing and triangular V-shaped connector. The bridge can be used for constructing beam, wall, slab and roof. Small-sized bride of the square pipe structure can be used for constructing all components in house buildings. The components can be processed in factory. Structure main body can be installed in construction site. Internal and external wall panels and roof section bars are paved. Gaps of walls, slabs and roof bridges can be filled with insulation and sound insulation materials.

Sanxin Company introduces internationally advanced extremely thin-walled cold bending light-steel structure building system (MET FRA - ME SYSTEM) technology and equipment as well as advanced house building concept. World leading (METFRAME SYSTEM) light steel structure full automatic intelligent housing design and production system is adopted. Computer intelligent structure design and automatic production flow of low-rise house structure are realized. ‘House modular assembly’ can be achieved. Efficiency of house building can be improved. Building cost can be reduced.

Extremely thin-walled cold bending light-steel structure building system adopts extremely thin-walled high strength light steel as main structure and material of the building. Material of light steel building structure is perfectly utilized.

Sanxin Company will focus on promoting and developing extremely thin-walled cold bending light steel structure buildings. Foreign intelligent and modular light steel building system is integrated into rapidly-developed building market inChina. People's traditional architectural concepts are constantly changed. It is matched with modern high-tech healthy, ecological, intelligent and energy-efficient building integrated systems. Green, energy-saving and environment-friendly residential buildings as well as integrated, modular, environment-friendly assembly multi-functional low-rise light steel structure buildings are constructed.
