Galvanized Steel Coil
Galvanized steel coil, also named GI coil or zinc coating coil. The most common and widely used type on the market is hot dip galvanized steel sheet metal in coil. Hot dip galvanized steel coils are first pickled to remove iron oxide from the steel surface. After pickling, they are cleaned in an aqueous solution of ammonium chloride, zinc chloride, or a mixture of both, before being hot-dip galvanized. Hot-dip galvanized steel coils offer advantages such as uniform coating, strong adhesion, and a long service life. |
