Electrolytic Rack Plating

For components up to 3 meters in length

Electrolytic rack zinc plating is ideally suited for larger and/or more delicate components, such as sheet metal parts, racks, tubes, and strips. At Wilbo, this process is carried out in a fully automated plating line based on an advanced alkaline process bath.

This technique — available at only a limited number of companies in the Netherlands — ensures excellent coating thickness distribution and results in a clean, uniform, and high-quality finish.

After plating, components are passivated as standard to enhance corrosion resistance. Within our rack plating line, we offer various passivation options, including blue (clear), thick layer (dickschicht), and black finishes. All passivations comply with the RoHS directive and are free of harmful hexavalent chromium. In addition, cobalt-free alternatives are available.

For additional protection and functionality, components can be treated with an optional topcoat. This further improves corrosion resistance and reduces the coefficient of friction, contributing to enhanced performance in application.

Fixcoat®: Black (Cr³⁺) zinc plating with exceptional corrosion resistance

A recent innovation within our portfolio is the Fixcoat® treatment. Applied after zinc plating and black passivation (Cr³⁺), this process provides exceptionally high corrosion resistance without the drawbacks of traditional systems, such as droplet formation.

With performance exceeding 720 hours in a neutral salt spray test, Fixcoat® offers a full-fledged alternative to zinc-iron and zinc-nickel coatings.
