Galvanized wire including
Electro-galvanized Iron Wire and Hot-dip Galvanized Iron Wire is a type of steel wire that's undergone additional protection processes.
Annealed wire is heated to restore ductility, but even that process leaves the metal with a few vulnerabilities. It can suffer from corrosion, scratches and will become much less effective over time. That leads to rust and can undermine the integrity of the wire, resulting in repair and even replacement costs.
Galvanized wire is an additional step. It involves dipping the metal into a bath of molten zinc. When the zinc dries it confers a secondary layer of protection. Zinc is tough and used in the production of galvanized steel more generally. It’s resistant to scratches and, most importantly of all, corrosion. This dramatically increases the longevity of the wire, keeps costs low and ensures continued use.
What are the benefits?
#1 Resistant to corrosion
Corrosion is caused by molecular exchange between metal and air. When metals come into contact with air, they lose some of their positive ions, leading to the formation of rust. Galvanized wire is highly resistant to corrosion. Zinc is renowned for its ability to resist oxygen and moisture and is often used to protect steel in the construction industry. A layer of zinc is frequently added to steel structures that are exposed to the elements. The zinc oxidizes instead of the steel, protecting the metal. Corrosion can be a big problem for wire, especially if it’s being used outdoors, but the layer of zinc confers protection that lasts.
#2 Increased lifespan
Zinc protected steel is renowned for its incredible lifespan, sometimes lasting hundreds of years before the coating needs to be reapplied. The same applies to galvanized wire. Although it can sometimes be harder to come by (since not all manufacturers are equipped to undertake the galvanizing process) and by extension slightly more expensive, galvanized wire pays for itself over time. Its tough exterior equates to a dramatically increased lifespan, so you’ll only have to replace it rarely, if ever.
#3 Scratch resistant
Wire is often exposed to all kinds of rough environments that can lead to scratches, damage and even breakages. Engineers across multiple sectors opt for galvanized wire because of its sheer robustness and ability to withstand all the rigors of long-term use. For example, 10 gauge galvanized wire is exceptionally durable and damage resistant. Depending on how you plan to use the wire, it can save both time and money. It limits breakages, lowers repair costs and means that you won't have to spend extensively on replacement wire.
