DX54D Z275 Hot Dipped Galvanised Steel Coil 1.5 mm Galvanised Steel Sheet

Hot Dipped Galvanized Steel Description

Hot-dip galvanizing, also known as hot-dip galvanised, is a surface treatment method in which metal are immersed in molten zinc to form a dense zinc layer on the surface of the steel. Hot-dip galvanizing has uniform coating, strong adhesion and long service life.Hot dipped galvanised steel coil has outstanding resistance to corrosion. The zinc layer acts as a protective shield, preventing water and air from reaching the steel surface, thus significantly extending the lifespan of the material.

The thickness of the zinc coating can be adjusted to meet specific requirements, allowing to be used in a wide variety of applications where rust resistance and strength are crucial.

Galvanised Coil Specification

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℃.
