Galvanization is a method that involves coating iron or steel with protective zinc to make it resistant to corrosion and extreme environment conditions. Galvanized iron wires (GI wires) are tough yet flexible, and are available in a variety of thicknesses and gauges.

Galvanized wire is created by coating carbon steel wire with zinc. This can be done through electro-plating or hot-dip galvanizing. Galvanized wire is used in applications where corrosion resistance is needed.
