Did you know that galvanization is the process of applying a protective zinc coating to steel or iron to prevent rusting? The most common method in Gi Coil Sheet metal fabrication shops is hot-dip galvanizing. This is the process of submerging metal parts in a bath of molten zinc to protect the metal.

This protection occurs in three different ways:

• The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.

• It acts as a sacrificial anode, which is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal from corrosion. This means that if the coating is scratched, the exposed steel or iron will be protected by the remaining zinc.

• The zinc protects its base metal by corroding before iron.

Galvanizing, or galvanization, is a manufacturing process where a coating of zinc is applied to steel or iron to offer protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot-dip galvanizing.
