Resistant to Damage. The zinc coating on a galvanized wire also provides the steel wire with a hard, protective coating. Exposed steel wire is relatively easily chipped, scratched and otherwise damaged in ways that weaken the strength of the wire.alvanized wire is used in many different industries due to its durability. This type of wire is easily identified because of the bright shine it usually holds.
