Galvanized steel wire refers to any steel wire product that has subjected to a galvanizing process to improve its resistance to corrosion. This process typically involves dipping the finished wire product into a bath of heated zinc compound to form a scratch- and corrosion-resistant coating across the entire surface of the wire. Although this coating is not considered to be a permanent anti-corrosion solution, it does greatly increase the wire's resistance to rust and thus considerably prolongs its service lifespan. Galvanized steel wire is available in a wide range of gauges and lengths, and is used extensively in the construction industry and in the industrial, do-it-yourself, and agricultural sectors.
Galvanizing is a particularly effective method of producing low cost, corrosion-resistant steel and iron products. Carbon steel and iron items are far more cost effective than similar stainless steel products, and the galvanizing process itself is not particularly costly. Galvanizing also offers very good corrosion protection so finished products are effective and cheap.
The galvanizing process protects products such as galvanized steel wire in the several ways. The first line of defense is formed by the physical barrier created by the galvanized layer. The second and most effective part of the anti-corrosion process involves what is known as "sacrificial anode" protection. The zinc coating is far less corrosion resistant than the steel, which causes it to be consumed by corrosion first, protecting the underlying wire.
