galvanic plating zinc coating
Owing to their resistance and anodic protection of steel against corrosion followed by the subsequent passivation (chromate treatment), the zinc coats are able to provide a quality anticorrosive surface finish of products with highly decorative appearance maintained.
Zinc coats are chromate treated using agents providing iridescent colour shades:
- blue chromate (without 6-valence chrome)
- thick-layer passivation (without 6-valence chrome)
- yellow chromate
- black chromate
The precipitated zinc layers shall conform to the customer’s requirements and comply with ČSN EN ISO 2081; layer thickness is ranging from 5 to 20 μm.
We use ZINKOGAL slightly acid zinc coating bath and ZINKOGAL alkali cyanide-free bath.
