ID 610mm GI Sheet Gauge 24 0.5 mm Galvanised Steel Plate

Product Specification

Galv Sheet Description

GI Sheet is a type of sheet that coating steel with a thin zinc layer, which serves as a barrier between the steel and the environment. The zinc coating acts as a shield, protecting the base steel from rust and oxidation,particularly suitable for outdoor applications, marine environments, and industrial settings where moisture and chemicals are present.

The zinc coating forms a metallurgical bond with the steel,the coating layer is bonded tightly to the steel, making it highly resistant to peeling, cracking, or flaking. If the is scratched or damaged, the zinc will sacrifice itself to protect the exposed steel, offering an additional layer of defense against corrosion.

Galvanised Steel Plate Specification

Galvanized Coil Surface Structure

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℃.
