Z275 Galvanized Steel Coil SGCC Sgce Galvanized Steel Coil

Galvanized steel coil is one of the hot-selling products. It's the cost-effective material, which combines durability and smooth appearance. It's also easy to paint and use. It is available in big, regular, small, and zero spangles. In addition, it features lightweight, aesthetics, and excellent corrosion resistance. Therefore, GI coil has been a new material for many fields, such as construction, shipbuilding, vehicle manufacturing, furniture, home appliances, etc.

Galvanized Steel Coil is in order to prevent the surface of the steel plate from corrosion to extend its service life, the surface of the steel plate is coated with a layer of metallic zinc, this zinc-coated steel plate is called galvanized sheet. It is used cold rolled steel coil as substrates by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure. It has excellent corrosion resistance, paintability, and workability due to zinc's characteristics.
According to the surface zinc spangle, it can be divided into galvanzied coil with spangle or galvanzied coil without spangle.

Hot Dipped Galvanized Steel Coil Production

The production and processing of galvanized steel coils can be divided into three steps: first, the entire coil is pickled to remove rust and dirt, so that the surface of the galvanized steel strip can achieve a bright and clean effect; after pickling, pass ammonium chloride or zinc chloride It is cleaned in an aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank for the galvanizing process; after the galvanizing process is completed, it can be put into storage and packaged.
