Tag: hot-dip galvanizing

Hot-dip galvanizing and zinc galvanizing are both effective methods of metal preservation, they are widely used in the production of raised floor accessories like pedestals, stringers. Difference in principle Hot-dip galvanizing is a chemical treatment that belongs to the electrochemical reaction. Zinc ingot is melted at a high temperature, with some auxiliary materials inserted. Then metal structures are immersed in a galvanizing bath so that a zinc layer is attached to them. Zinc galvanizing refers to electroplating, it is a physical process. Zinc salt solution is electrolyzed, so that a zinc layer is attached to metal structures. Difference in parameter After the process of hot-dip galvanizing is completed, when steel thickness is not less than 5mm, the average zinc layer weight is not less than 610g/sqm; when steel thickness is less than 5mm, the average zinc layer weight is not less than 460g/sqm. Zinc layer thickness of zinc galvanizing is
