Hot Dip Galvanized Mild Steel Wire
Galvanized Iron (GI) Wires are manufactured from high-quality steel wire rods coated with a protective layer of zinc through the hot-dip galvanization process. This zinc coating acts as a shield against corrosion and rust, significantly enhancing the wire's durability and service life in diverse environmental conditions. The thickness of the zinc coating, measured in grams per square meter (GSM), plays a crucial role in determining the wire's corrosion resistance and overall performance. Available in a wide range of diameters and coating specifications, GI Wires offer an excellent combination of strength, flexibility, and reliability. Known for their high tensile strength, superior ductility, and ease of handling, GI Wires are widely used across industries such as construction, agriculture, fencing, power transmission, cable armouring, wire mesh manufacturing, and general engineering applications.
