Electric zinc galvanizing with trivalent chromate conversion (blue/white or yellow converter).  Trivalent chromate conversion with yellow converter is one of a variety of chromate conversion coatings available for use on Eberhard parts.  Chromate conversion coatings are produced on various metals through chemical or electrochemical treatment with mixtures of trivalent chromate conversion and certain other compounds.  Through these treatments, the metal surface is converted to a superficial layer containing a complex mixture of trivalent chromate conversion compounds. Thickness from 12~20micro

Optional Organic Coatings & Mechanical Coatings, a kind of non-electric zinc alloy coatings that are enviroment-friendly coating methods, coating layer thickness from 15 up to 25um, mostly zinc_aluminium coating, zinc_nickle coatings with an extra baked film layers. High anti-corrosin features, from 500 up to 2000hrs, Max 3000hrs (Real test hours)
