Hot Zinc Galvanizing Versus Electroplated Zinc





Dear Sirs:

We would appreciate your advice on the following:

Thanks in advance,

Corrosion resistance of zinc is directly related to its thickness. Since it will be difficult to reach 80 microns thickness with electroplating, it is not possible to solve your problem. Hot dip zinc plating creates intermetallic compounds between steel and zinc layer. This layer is very brittle and easy to break if you deform the material after plating. That is the reason why electroplating is preferred for deformed steel sheet materials.

Good Luck

Hot dip, zinc coatings generally provide superior rust protection. Normally, the hot dip process has a thicker coating, than electro. The heavier the coating, the more protection. It may be difficult to electro galvanize 80 microns.
