Hot-dipped galvalume steel coil is substrated on cold rolled steel(CRC) in various strength and specification.
Hot-dipped galvalume steel coil is substrated on cold rolled steel(CRC) in various strength and specification. Coating composition is 55% aluminium in weight ratio, 43.5% zinc, and 1.5% silicon. Hot-dipped galvalume steel coil is a kind of quaterany alloy steel with Al-Fe-Si-Zn four-element.
The Anti-Fingerprint treatment means to make a organic coating of anti-fingerprint film on the surface of the hot-dipped galvalume steel coil. Compared with Galvanized Steel Coil, it has more superior corrossion resistance performance. Hot-dipped Galvalume Steel Coil also has good anti-heat resistance and oxidation resistance. The service lifetime can be longer than same grade Galvanized Steel by 3 times. The strong corrossion resistance performance is mainly because of the element Aluminium. When the zinc element is worn-out, the element Aluminium will form into compacted oxide layer to protect the coils not being corrossived further. Also hot-dipped galvalume steel coil is more economic than galvanized steel coil, because the surface coating density of alu-zinc is less than zinc, the plate area for hot-dipped galvalume steel coil is 3% larger than galvanized steel coil.
Product Features: Good corrossion resistance, good anti-heat resistance,oxidation resistance,more economic.
With perfect zinc spangle on the surface, hot-dipped galvalume steel coil is mainly used in constructions, light industry,automobile, agriculture, animal husbandry, fishery, commercial civil electronics and other industries. Such as civil building roof panels and roof grate,home appliances shell, kitchen utensils, anti-corrosive parts of automobile, food storage tools, freezing processing tools, storage and transportation equipment, packaging equipment and etc.
