Galvanized sheet is mainly used: a large number of galvanized sheet plate used in automobile Manufacturing, cooler, construction, ventilation and heating facilities and furniture manufacturing and other field. Galvanized become important steel anticorrosion method, not only because the zinc can be formed in the steel surface protective layer of dense, but also because of the zinc has the effect of catholic protection, when the galvanized layer damaged, it can still through the catholic corrosion protection to prevent the iron base. Construction industry/Household appliances/Furniture industry/Transportation industry. Other instrument shell, dustbin, billboards, clocks, photographic equipment, meter and other hot galvanized steel sheet, color coating steel plate is hot aluminum zinc plate, electric galvanized sheet as the substrate, such as the surface pretreatment

1. Surface: Chromated, Unoiled, tension-levelled, skin-passed

2. Spangle: regular spangle/ minimum spangle/ zero spangle

3. Coils id: 508mm/610mm or others

4. Size:(0.2-3.0)mm X(1000-1250)mm X C

5. Application: they are mainly used in construction, the light industry, the automobile, agriculture, animal husbandry, and fishery industry and commercial business, etc. in construction industry, it is mainly used to make roof board and grill for industrial and civilian buildings: in light industry, it is mainly used to make casing of household electric appliances, civilian smoke stack, in automobile industry, it is maily used to make the parts of the automobiles, in agriculture, animal husbandry and fishery industry, it is maily used to make the packing equipment, the skin-passed galvanized steel in coils with zero spangle is largely used as the base metal of the color-coated steel sheets.

Hot Dip Galvanized coil produced by JIN LAI,is coated with zinc using a continuous and controlled process. The tight metallurgical bond between the steel and coating takes place in a continuous galvanizing line. This process results in a material with the strength and formability of steel and with the corrosion protection provided by zinc. The zinc coating protects the base metal from external corrosive elements in two main ways, by acting as (1) a physical barrier and (2) a sacrificial anode.
