DX51D+Z Galvanized Steel Coil
Galvanized steel coil is to prevent corrosion on the
surface of steel coil and prolong its service life.
A layer of metal zinc is coated on the surface of steel coil,
which is called galvanized steel coil.

Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc’s characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Galvanized Steel Coil Types
According to the processing method, we divide galvanized steel into the following categories:
1. Hot-dip Galvanized Steel Coil
As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:
1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.
2) The cost of hot-dip galvanizing is cheap.
2. Electro-galvanized Steel Coil
Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
