Product Description
GI Coil Description
The full name of GI sheet is galvanized iron sheet, which is a steel sheet treated with zinc coating to prevent corrosion and extend service life. According to different galvanizing processes, GI sheet can be divided into hot-dip galvanized sheet and electro-galvanized steel sheet. Hot-dip galvanizing forms a heavy protective layer by immersing the steel sheet in molten zinc, while electro-galvanizing coats the steel surface with a thinner layer of zinc through an electrochemical process.
Galvanized steel coils are widely used in the construction industry, especially roofing materials. Galvanized steel coils are widely used to manufacture roof panels, wall panels and other structural components due to excellent corrosion resistance and durability. Galvanized steel prevents rust by coating the steel sheet surface with a layer of zinc to extend its service life.

Galvanized Coil Surface Structure:Small,Large,Zero.Select as per your requirement
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.
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 Features
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.
- Excellent anti-corrosion:
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.
- Strong durability:
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.
- Good workability:
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.
- Thermal resistance
Galvanized steel has good thermal resistance,can be used for long time without discoloration below 230℃, and it will discolor when it exceeds 250℃.
