The technology and product configuration of steel structure is very mature, with high degree of industrialization. It is the crystallization of North American construction technology and building materials industry. The galvanized steel sheet used in building structure has excellent corrosion resistance and durability, and its service life under normal use is 275 years. It has the following four characteristics:
1. The structure is stable.
2. The cost is low.
3. The space span of light steel villa is larger than that of concrete building.
4. The construction period is much shorter than that of conventional buildings.
