Zinc Plating
Services
Professional electroplating solutions delivering superior corrosion resistance and dimensional precision for automotive, industrial, and aerospace components. Compliant with RoHS, ASTM B633, and ISO 2081.
Our controlled electrodeposition process ensures uniform zinc coating thickness across complex geometries and tight-tolerance components.
Pre-Treatment & Cleaning
Parts are degreased, acid-pickled, and activated to remove oxide layers and contaminants for maximum adhesion.
Electrodeposition Bath
Parts immersed in zinc sulfate or zinc chloride electrolyte bath with controlled current density and temperature.
Chromate Passivation
Optional trivalent chromate passivation enhances corrosion protection with clear, yellow, or black finish options.
Inspection & QC
100% visual inspection with XRF thickness measurement, adhesion testing, and salt spray verification.
Our zinc plating process meets or exceeds international standards for coating quality and performance.
A selection of completed zinc plating projects delivered to our customers across automotive, industrial, and hardware sectors. Every part ships with full CoC and XRF report.
