Types of surface treatment of stainless steel screws: eco black zinc, Dacromet, sandblasting, polishing, electrophoresis, gold plating, passivation, vacuum plating and so on.

Environmental Black Zinc process: degreasing – cleaning – weak acid etching – electro-galvanizing – cleaning – passivation – cleaning -lacquer.

Dacromet’s surface treatment process is: organic solvent degreasing – mechanical blasting – spraying – baking – secondary spraying – baking – drying.
