The hot-dip galvanized steel plate water tank has a thick and dense pure zinc layer covering the surface of steel, which can isolate the iron substrate from contact with corrosive solutions and protect the steel substrate from corrosion. It is a process where zinc is in a liquid state and undergoes complex physical and chemical processes to coat steel with a thick pure zinc layer, which also generates a zinc iron alloy layer. This plating method has the corrosion resistance characteristics of electrogalvanizing, and due to its zinc iron alloy layer. It also has strong corrosion resistance that cannot be compared to electrogalvanizing. Therefore, this plating method is suitable for strong corrosive environments such as strong acid and alkali mist.

Due to the excellent ductility of zinc, its alloy layer adheres to the steel base, so hot-dip galvanized parts can be formed through cold stamping, rolling, wire drawing, bending, etc. without damaging the coating; After hot-dip galvanizing of steel structural components, it is equivalent to annealing treatment, which can change the mechanical properties of the steel substrate, stress during forming and welding of steel components, and has a good effect on turning and processing of steel structural components. The surface of the hot-dip galvanized parts is bright and beautiful.
