High Durability Galvanized Steel Coil
Brief Introduction
Galvanized Steel Coil gets coated in layers of zinc because rust
won't attack this protective metal. The most external layer is all
zinc, but successive layers are a mixture of zinc and iron, with an
interior of pure steel. These multiple layers are responsible for
the amazing property of the metal to withstand corrosion-inducing
circumstances. Zinc also protects the steel by acting as a
"sacrificial layer." If rust does take hold on the surface of
Galvanized Steel Coil, the zinc will get corroded first. This
allows the zinc that is spread over the breach or scratch to
prevent rust from reaching the steel. For countless outdoor,
marine, or industrial applications, Galvanized Steel Coil is an
essential fabrication component.
The Protection Principle
1. Anodic reaction: Zn-2e=Zn2+
(The alloy coating loses electron, sacrificing itself in
dissolution.)
2. Cathodic reaction: Fe2++2e=Fe
(Fe gains electron reaction, being protected)
