2mm Galvanised Sheet Zinc Coated Steel Sheet DX53D Z30

Galvanised Zinc Sheet Description

Zinc-coated steel sheets, also known as galvanised steel sheets,coated with a layer of zinc through galvanisation process.This zinc coating serves as a protective barrier,protect the steel against rust and corrosion while exposure to moisture and air.The zinc layer has uniform thickness and strong adhesion.No peeling and good corrosion resistance.The surface is very smooth and clean,zinc flower is symmetrical,beautiful.

The zinc layer creates a sacrificial barrier, meaning that even if the coating gets scratched or damaged, the zinc will still protect the exposed steel, significantly increasing the material’s lifespan. Under normal use conditions, gi sheet can be used for decades without frequent replacement or repair.

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℃.
