Galvanized Strip Coil

Main Products

galvanized strip coil

Galvanized strip coil is a coil of flat-rolled steel or iron that has undergone a galvanization process. Galvanization is a method of protecting steel or iron from corrosion by coating it with a layer of zinc. The process involves immersing the steel or iron in a bath of molten zinc, allowing the zinc to form a protective layer on the surface.
