Title Color Coated Substrate Classification
Description The product obtained by coating the organic coating on the hot-dip galvanized steel sheet is the China high quality prepainted color galvanized coil. In addition to the protective effect of zinc, the hot-dip galvanized color-coated plate also protects against rust and has a longer service life than hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180 g/m2 (double-sided), and the galvanizing amount of the hot-dip galvanized substrate for external use is up to 275 g/m2. The base of the hot sale prepainted galvanized steel coil uses a hot-dip galvanized steel sheet as a new coated substrate, usually containing aluminum and zinc in an amount of 150 g/m 2 (double-sided). The corrosion resistance of the hot-dip aluminum-zinc plate is 2-4 times that of the hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490 ° C does not cause severe oxidation or scale formation. The ability to reflect heat and light is twice that of hot-dip galvanized steel sheets, and a reflectance greater than 0.75 is an ideal building material for energy savings. China high quality prepainted color galvanized coil substrate is made of an electrogalvanized sheet. The product obtained by baking with the organic coating is electro-galvanized color-coated plate. Because the zinc layer of an electro-galvanized sheet is thin, the zinc content is usually 20/20g. /m2, so this product is not suitable for outdoor wall, roof, etc. However, due to its beautiful appearance and excellent processing properties, it can be mainly used in home appliances, audio, steel furniture, interior decoration and so on.
