The technology and product configuration of light steel structure are very mature, and the degree of industrialization is high, which is the crystallization of the development of construction technology and building materials industry in North America for nearly 100 years. The galvanized steel plate used in the building structure has excellent corrosion resistance and durability, and its service life under normal use is 275 years. The seismic performance of light steel structure is much better than that of traditional concrete and brick housing. At the same time, because the structural weight of the light steel structure is light, the weight per unit area is only equivalent to 1/4 of the weight of the brick-concrete structure of the same area, so its foundation is simple and suitable for most geological conditions.
