Introduction：Steel structure villa system technology refers to the technology by which buildings under the sixth floor can be built with 100% cold-formed steel material. The main building components of the technological system consist of cold-formed steel and a small crane span structure which is made up of light thin-walled sqaure tube welded by galvanized cold-formed at high frequency and triangular V-type connectors.
The crane span structure of square tube structure can be used in the production of all building components such as beam, wall, floor and roof, which are processed and finished at the factory, and then are transported to the construction site for installation of the main structure. After that, internal and external wall panels and roof panels are laid, while the heat and sound insulation materials are to be filled into the interspaces between walls, floor panels and roof crane span structure.
Applications：Civilian self-built residential housing; Commercial, industry office and housing; Leisure areas, tourist areas and holiday homes on the ecological farm.
