Abstract: A galvanization system comprising an alkaline galvanization bath, a positive electrode, and a negative electrode is provided. The alkaline galvanization bath comprises galvanizing solution including about 7 to about 60 g/l of Zn, about 70 to about 200 g/l of alkali hydroxide and about 0.01 to about 5 g/l of additives. The positive electrode is insoluble in the galvanizing solution, having an opposed surface to an object which is supposed to be set in the alkaline galvanization bath and galvanized. The opposed surface of the positive electrode is formed in a rectangular pattern having a side equal to or less than 30 mm or in a circular pattern having a diameter equal to or less than 30 mm. The galvanization system can produce a galvanization membrane of excellent appearance.

The alkaline galvanization bath comprises galvanizing solution including about 7 to about 60 g/l of Zn, about 70 to about 200 g/l of alkali hydroxide and about 0.01 to about 5 g/l of additives. The positive electrode is insoluble in the galvanizing solution, having an opposed surface to an object which is supposed to be set in the alkaline galvanization bath and galvanized. The opposed surface of the positive electrode is formed in a polygonal pattern having a side equal to or less than 30 mm, which connects arbitrary two apexes of the pattern, in a polygonal pattern having a vertical line equal to or less than 30 mm, drawn between an arbitrary apex and an arbitrary side of the pattern, or in a circular pattern having a diameter equal to or less than 30 mm. The galvanization system can produce a galvanization membrane of excellent appearance.
