Great Lakes Metal Finishing, Inc has developed a proprietary olive drab chromating process that removes the inherent iridescent appearance from the olive drab finish. The process produces an even, matte finish, which is required for military operations. The olive grab chromate was developed to match olive drab paint, thus greatly reducing the cost for an olive drab finish.

The olive drab chromate is rated for a minimum of 96 hours to white corrosion, however many of our in-house results have far surpassed that level.

How do we meet customer’s expectations?

Great Lakes Metal Finishing, Inc strives to give our customers exactly what their parts need and even exceed their expectations. The majority of the work performed at GLMF is plated to a customer’s individual zinc or zinc nickel plating specifications. No matter the plating thickness, bake cycle, chromate, or salt spray requirement, GLMF will deliver exactly what is required to meet the specification callout. If you do not know what is needed for your part, we will collaborate with you to find the appropriate zinc nickel or zinc electroplating that is necessary.

How do we ensure plating specifications are met?

GLMF performs on-site daily testing of our cleaners, acids, plating tanks, passivates, and chromates to ensure they are all in compliance with ideal operating parameters. To ensure your parts are getting the proper plating deposit for every job, our operators complete online thickness checks using one of our x-ray machines. In addition to online checks, all parts pass through our quality department for a final inspection of appearance and thickness. This final step helps to ensure proper plating specifications were met.
