Classification and production process of galvanized coil

① Galvanized coil The thin steel plate is immersed in a molten zinc bath, and a layer of zinc is attached to the outer surface of the thin steel plate. At present, it is mainly consumed through a continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a galvanizing tank where zinc condenses.

② alloy galvanized sheet bending machine this steel plate is also hot-dipped, but immediately after coming out of the tank heated to about 500 ℃, constitute the zinc and iron alloy coating galvanized sheet has good coating adhesion and weldability.

③ galvanized coil electroplating consumption of galvanized steel sheet processing performance is good. However, the coating of the galvanized pipe is thinner than that of the hot galvanized sheet, and the corrosion resistance is also poor.

4 single-sided galvanized and double-sided differential galvanized coil single-sided galvanized steel, that is, single-sided galvanized products in welding, coating, rust disposal, processing and other aspects than double-sided galvanized sheet has better compliance. In order to restrain the defects of one side is not galvanized, the other side is coated with a thin layer of galvanized plate, that is, double-sided differential speed galvanized plate.

⑤ alloy, composite galvanized coil This is an alloy made of zinc and lead, zinc and other metals, and even a composite steel plate galvanized pipe steel plate not only has excellent anti-rust performance, and coating performance is good.
