Our Premium Metal Finishing Services

Zinc Nickel Plating

Our zinc nickel plating offers superior and reliable corrosion resistance, with performance exceeding 700 hours to red rust in salt spray testing.

Trivalent Chromate (Clear or Black)

Trivalent chromate plating compliments base zinc nickel plating by offering a sealing option that adds hundreds of hours to the performance of zinc nickel plating. While clear chromate is the most commonly requested option, we also offer black chromate when reflectivity is a concern.

Internal Testing and Validation

We have the ability to validate our performance internally with salt spray corrosion testing as well as measurement of zinc and alloy content via X-ray fluorescence. These internal capabilities allow us to certify our processes to both industry and OE-specific requirements.
