Great Lakes Metal Finishing

Great Lakes Metal Finishing, Inc offers both trivalent black and hexavalent black chromate as two of our many options for zinc plating services. GLMF's tight tolerance metal finishing work can accommodate individual zinc or zinc nickel plating specifications. We can achieve the desired plating thickness, bake cycle, chromate, or salt spray requirement for automotive, industrial, military olive drab, and appliance applications. Our quality olive drab metal coating sets us apart from most metal finishing companies. We also offer trivalent yellow, hexavalent yellow and trivalent clear metal coatings. Our unique trivalent yellow passivate is ideal for our customers who require their products to be ultraviolet (UV) stable as our coatings do not contain dye.
