Hot-dipped galvanized steel sheets
Hot-dipped galvanized steel sheets
There are thousands of galvanizing methods，Only hot-dip galvanizing is the most powerful!
Hot-dip galvanizing: Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to produce a zinc-iron alloy layer, thereby combining both the substrate and the coating. Hot-dip galvanizing is a process in which the steel parts are first pickled, in order to remove iron oxide from the surface of the steel parts. After pickling, they are cleaned by passing through a bath of ammonium chloride or zinc chloride in aqueous solution or a mixture of ammonium chloride and zinc chloride in aqueous solution, and then sent to a hot dip plating bath.
Hot-dipped galvanized steel sheets Advantages: uniform plating, strong adhesion, long service life.
