Galvanization Definition:Hot-dipped galvanization What Produces a layer of Zn on the surface which is not continuous with steel metallurgically. Steel is dipped into the molten bath of Zinc @460ºC for achieving the coat. Steel is made the cathode in the electrolytic cell there by forming the coating by Electroplating process. The surface finish is not smooth, dull finish.
