In the manufacturing industry, Galvanized steel wire is mild steel/high carbon wire that have been coated in zinc to make them corrosion resistant. Ungalvanized Mild Steel/High Carbon Wire will rust when exposed to moisture, either in the form of rain or ambient humidity. The rust and surface deterioration will ultimately lead to performance failure. To prevent steel wire from rusting there are two options:
As with most decisions in manufacturing, both of these options are primarily evaluated in terms of cost.
Occasionally switching from mild carbon/low carbon steel to another metal that does not rust such as stainless steel or aluminum is not an option simply because of the difference in cost: Economically a substitution doesn’t make sense. Aluminum is more expensive than steel, and stainless steel is a lot more expensive that aluminum. Moreover steel might have certain physical characteristics, such as strength or weight that prohibits a switching for a specific application. The next option is to protect the steel with a physical barrier such as paint or a coating – this is what galvanizing does best.
