Zinc adhesion and zinc layer thickness
1. When the thickness of the plated part is 3-4 mm, the amount of zinc adhesion should be less than 460 g/m, that is, the average thickness of the zinc layer is not less than 65 μm.
2. When the thickness of the plated part is more than 4 mm, the amount of zinc adhered should not be less than 610 g/m, that is, the average thickness of the zinc layer is not less than 86 μm.
3. Coating uniformity: The galvanized layer is substantially uniformly etched five times without iron by using a copper sulfate solution.
4. Adhesion of the coating; the zinc layer of the plated part should be firmly bonded to the base metal and have sufficient adhesion strength, and it does not fall off after the hammering test, and does not protrude.
