Zinc coating with colorless RoHS compliance passivation Zinc coating with colorless chromate passivation Zinc coating with colorful chromate passivation Zinc coating with no additional treatment The type of passivation is determined according to the required characteristics, and is divided into groups: Type The Zinc coating on the steel does not last shiny for long, and so a further thick layer coating is added, called passivation. There are different passivation colors: shiny blue- white, colorful-yellow, black and olive green. The coating is made according to demand, where the distribution is as follows: Our Zinc coating is carried out according to:ĪSTM B-633 ELECTRODEPOSITED COATINGS OF ZINC ON IRON AND STEEL. The Zinc coating provides a smooth look as well as good anti-corrosive protection. The rust not only harms the aesthetically smooth look, but also its mechanic needs. Iron metals rust relative quickly, even in a non-corrosive environment. ![]()
