Galvanised Steel Plate Description
Galvanized steel plate is a steel plate with a layer of zinc on the
surface. Through hot-dip galvanizing or electroplating, the steel
is given a protective zinc layer, which improves its anti-corrosion
resistance. This zinc layer can prevent the steel from direct
contact with corrosive substances such as air and moisture, greatly
extending the service life, especially in harsh environments such
as humidity and salt spray.
Steel is prone to rust due to exposure to air and moisture, but the
galvanizing process covers its surface with a corrosion-resistant
zinc layer that can effectively block moisture and oxygen and
prevent rust. This makes galvanised steel an ideal building
material in high humidity, coastal areas and industrial
environments.

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.
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℃.
