The galvanized coating is a piece of metal with a bath of zinc to protect it from oxidation and corrosion while improving its visual appearance. The metal parts are dipped in a bath of liquid zinc at melting temperature of 900 to 950 degrees Celsius, obtaining a galvanized. Zinc may also be adsorbed if applied as a powder and placed in a suitable furnace (sheradización). Small parts are treated in rotating drums in bulk, while for the larger parts zinc frames are used to decrease surface friction on the material. After the electrolytic bath a coating thickness is achieved.
