Hot-dip galvanizing is coated with a layer of zinc.The substrate used in hot-dip galvanizing is cold-rolled, and the zinc plating on the cold-rolled sheet is called galvanizing. Ordinary hot-dip galvanizing is 80 grams. 140 and 275 are high zinc layers, and the purpose of hot-dip galvanizing is to prevent the steel from rusting.
