Sacrificial protection
Zinc electroplating
As specialist zinc platers, we apply zinc plating (zinc electroplating) to steel components: a sacrificial zinc coating that corrodes in preference to the steel beneath, protecting the part long after minor damage. It's a cost-effective, dimensionally accurate finish with a range of passivate colours and topcoats to suit cosmetic and performance needs.

Passivates & topcoats
A passivate is a thin conversion layer applied over the zinc to boost corrosion resistance and set the colour: clear/blue, black, or coloured. Topcoats such as Enseal 40 and JS500 add further protection and consistency. For the highest corrosion performance on fasteners and critical parts, pair zinc plating with SurTec 650 trivalent passivation (see SurTec 650 conversion coating).
