ASTM A653 Standard Hot Dipped Galvanized Coil , Good Mechanical
Property
Hot-dip galvanizing is the reaction of molten metal with an iron
substrate to produce an alloy layer, thereby combining the
substrate and the plating layer. Hot-dip galvanizing is to pickle
iron and steel parts first. In order to remove iron oxide on the
surface of iron and steel parts, after pickling, it is cleaned in
an ammonium chloride or zinc chloride aqueous solution or a mixed
solution of ammonium chloride and zinc chloride.And then sent to
the hot-dip plating bath. Hot-dip galvanizing has the advantages of
uniform coating, strong adhesion and long service life.
