Hot dipped Galvanized Steel coil

JIS G3302 Hot dipped Galvanized Steel coil

Galvanized steel is defined as a carbon steel sheet coated with zinc on both sides. There are two main processes used to produce galvanized steel: continuous hot dipping and electro-galvanizing. The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer.

Most important, our hot-dipped galvanized steel coil and sheet service capabilities include slitting,cutting to length, blanking, degreasing and brushing, stretcher leveling and metallurgical support.

Advantages of Galvanized Steel

The main advantage of galvanized steel is its corrosion resistance. The zinc coating serves as a barrier between the steel and the environment and will sacrifice itself in order to protect the underlying steel; Meaning the zinc will degrade much sooner than the steel itself. Additionally, it offers good processability and formability.
