Galvanization produces GI wire, or galvanized iron wire. The wire is rust-resistant due to an anti-rust protected zinc metal covering.Steel wire rope that has been zinc-coated is known as galvanised wire rope. The coating protects the steel from moisture in the air, which helps to keep the wire rope from rusting. This wire rope is suited for usage in maritime environments where it is subjected to wet, damp, and humid circumstances.
