Deep Drawing Quality JISG3302 SGCD3 Hot Dip Galvanized Steel Coil
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.

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
