 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.



Galvanized steel coil (GI) is mainly used in many fields such as construction, automobile, metallurgy, electrical equipment and so on. Construction-roofs, doors and windows, rolling shutters and hanging skeletons Automobile-vehicle shell, chassis, door, trunk lid, fuel tank and fender metallurgy.
