Coated steel is a specially treated steel whose surface is covered with a thin coating or plating. This coating can provide good anti-corrosion properties and decorative effects on steel, extending its service life. Common coated steels include hot-dip galvanized steel, electro-galvanized steel and organic-coated steel.

Hot-dip galvanized steel uses a hot-dip galvanizing process to coat a layer of zinc on the surface of the steel to form a protective layer that prevents the steel from coming into contact with oxygen, moisture and other substances from the outside, thereby achieving the anti-corrosion effect.

Electro-galvanized steel uses a method of electrolytic deposition to evenly coat a layer of zinc on the surface of the steel, which also has good anti-corrosion properties.

Organic coated steel is a layer of organic coating applied on the surface of the steel, usually made of epoxy resin, polyester, fluorocarbon and other materials. It not only has anti-corrosion function, but also provides rich decorative effects, making the steel more beautiful.

Coated steel is widely used in construction, automobiles, ships, home appliances and other fields, providing these industries with dual guarantees of durability and aesthetics.
