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)
