Blue chromated

The blue chromate is the protection of zinc coated surface and has the significant importance for its use in aggressive conditions. This protection (blue chromate) is made by chemical treatment of excluded elements of zinc in solutions containing the compound of chrome. By this process of direct chemical reaction is created conversion layer with many of interesting conditions possible to use in a wide range of technical uses.

Conditions of blue chromated steel strip:

• improve the surface design
• improve the corrosion protection of zinc-coated steel strip
• improve the antifinger protection
• improve the adhesion of further implemented paint or coating
