At the beginning of the 20th century with the start of the Industrial Revolution, the scale of the iron and steel industry in some developed countries expanded rapidly, and steel-structured housing has developed preliminarily. So far, the development history of steel structure housing technology has reached more than 100 years in developed countries in the world.
China's light steel construction has alsodeveloped rapidly in the last decade. In September 2016, the General Office of the State Council issued the "Guiding Opinions on VigorouslyDeveloping Prefabricated Buildings". In September 2018, the Ministry of Housing and Urban-Rural Development issued the "Technical standard forcold-formed thin-walled steel multi-storey residential buildings, formed thin-walled steel multi-storey residential buildings ", while the building association and some provinces and cities have also formulated and promulgatedindustry and local standards. China Light Steel Housing also creatively improved the filling materials and construction technology, such as polyurethane filling, Expanded Polystyrene (EPS) molding customization, foamed concrete pouring, and self-waterproofing of the structure, and other technologies, which greatly improved thetechnical indicators of the building.
China produced the first cold bending mill and built a lightsteel structure plant in 1958. Thelight steel villa appeared in China early. The information technology was notdeveloped well at that time, so it took many years for people to understand thelight steel villa. With the era of advanced information, everything in life isconstantly changing. Light steel villas have also undergone major changes. Three technical standards andregulations represent the development process of cold-formed thin-walled steel houses (light steel houses for short) in China.
Generally speaking, the steel structure housing system is very mature in terms of modular design, standardized production, assembly construction, energy saving, fire protection and earthquake resistance, especially the application of supporting components with less pollution and short cycletime such as matching walls, floor slabs, and roofs.The Philippines has a hot climate,frequent typhoons, many earthquakes, and limited island country resources. This advanced and environmentally friendly light steel structure building system is bound to become a new trend.
