The color steel plates produced from cold-rolled substrates have a smooth, beautiful appearance and the machinability of cold-rolled plates; however, any small scratch in the surface coating exposes the cold-rolled substrates to air, which quickly leads to red rust in the exposed areas. Therefore, these products should only be used for temporary isolation measures and for indoor applications where the requirements are not high.
Hot-dip galvanized color coated steel plate is a product made by applying organic coatings to hot-dip galvanized steel. In addition to the protective function of zinc, the organic coating on the surface of hot-dip galvanized color coated steel plate also acts as a barrier to prevent rusting and lasts longer than hot-dip galvanized steel plate. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (both sides), and the maximum zinc content of hot-dip galvanized substrates for external building use is 275g/m2.
These products are generally used in the construction of roofs and walls of steel structure warehouse, aircraft hangar, stadium roof, exhibition hall, etc.
On request, hot-deposited zinc-aluminized steel sheets can also be used as color coated substrates (55% AI-Zn and 5% AI-Zn).
Electro-galvanized sheet is coated with organic paint. Due to the thin zinc layer of electro-galvanized sheet, which usually contains 20/20g/m2 of zinc, this product is not suitable for outdoor walls and roofs. However, because of its beautiful appearance and excellent processing performance, it is mainly used for home appliances, stereos, steel furniture and interior decoration.
SAFS devotes to the construction of space frame which apply to diverse projects such as aircraft hangar, bulk storage，warehouse and skylight roof, etc.
