Hot-dip galvanizing consists of two main stages: preparation of the surface and the galvanization itself. At the start of the galvanizing process, the surface of the unworked steel is contaminated with substances such as rust and calamine, produced by oxidation, and other materials such as oil, paint and other residues from previous work. To remove these substances, chemical degreasing and pickling processes are used.
