Galvanished Iron Wire (Gi Wires)
The process adopted by the company for manufacturing G.I. (GALVANIZED IRON) wires incorporates the latest in annealing, pickling and Hot Dip Galvanizing process. The annealing process uses a closed chamber, heavy oil fired furnace where by the requirement of lead as a heating medium is eliminated thus eliminating toxicity. The galvanizing is done using 99.99% pure Electrolytic Zinc. Prior to galvanizing, the wires are thoroughly picked, rinsed and given flux coating for achieving good adhesion of zinc to the base metal. The wiping system for coating control also varies according to the galvanizing coating needed (light, medium, heavy) for achieving a smooth and required coating of zinc throughout the base metal.
Mild steel drawn wire passes through molten zinc and coating is done. Bright, Shining and free from foreign particles. IS - 4826 IS - 280
