Galvanized steel coil is produced by carbon steel coil treated with galvanizing, and a layer of zinc is coated on the surface to enhance its corrosion resistance and extend its service life. This galvanized coating protects the steel substrate from damage typically caused by moisture or temperature changes. The steel is dipped into molten zinc, which then bonds itself to the steel and becomes part of its chemical composition.
According to the production and processing methods, it can be divided into the following categories:
Zinc Spangle is a surface morphology of hot-dip pure zinc coil, when the steel strip passes through the zinc pot, the surface is coated with liquid zinc, and then in the process of natural solidification of the zinc layer, the zinc grain nucleus grows and zinc spangle appears.The surface of the hot-dip pure galvanized coils produced had zinc sparks of various sizes and shapes.
The zinc coating is a well-known and effective way of adding a layer of protection against bare steel from the natural elements that cause corrosion. Not only will zinc play the role of a barrier between the environment and the steel, but it will also allow itself to decompose first to protect the steel underneath and promote its longevity.

Galvanized steel sheet is cut from galvanized steel coil, the base material is cold rolled steel, it has good processing performance. The galvanized sheet coated with a zinc layer,features a smooth, flat,uniform thickness, strong adhesion, no peeling during processing, good corrosion resistance,and excellent adhesion to paint film. It can withstand high temperatures up to 315 ℃ and has excellent surface conductivity. The surface is smooth and clean, the size is accurate, the board surface is straight, the spangles are even and beautiful.
Galvanized steel coils have high adhesion,corrosion resistance, and precisely controlled coating thickness. In addition,Galvanized steel is easy to process and weld, and also has a long service life when exposed to the atmosphere.
Galvanised Steel has excellent corrosion resistance,the zinc coating layer has better electrochemical protection on steel than painting and plastic coating.It can last for decades of years without any problem of peeling off,and also higher collosion and scratch resistance.
Not only will the zinc coating play the role of a physical barrier but also protects the steel underneath through electrochemical reactions (sacrificial anode action) when the coating is scratched or damaged.
Hot-dip galvanized steel coils maintain the processability of steel, and the zinc layer is thin and uniform, which does not affect the performance of steel during processing and forming.
Galvanized steel has good thermal resistance,can be used for long time without discoloration below 230℃, and it will discolor when it exceeds 250℃.
We offer value-added services including polishing, annealing, heat treatment, and welding for GI steel.
