Galvanized steel coil is a type of steel coil that has undergone surface galvanizing treatment. It is coated with a layer of zinc on the surface of a substrate (such as cold-rolled or hot-rolled steel plate) to improve its corrosion resistance and service life. The galvanizing process mainly includes two methods: hot-dip galvanizing (hot-dip galvanizing) and electroplating galvanizing. Among them, hot-dip galvanizing is more common, with a thicker zinc layer and stronger protection.
