Prevention → Recycle → Treatment → Disposal
Our Systems allow for 100% treatment of all waste streams prior to discharge.

At Great Lakes Metal Finishing, we pride ourselves on rigorous quality control, exceptional customer service, and a superior zinc and zinc nickel coating process. Additionally, we are committed to using environmentally friendly plating practices and use a non-cyanide solution in our chromate coating process. By using this eco-friendly alternative to the cyanide solutions used by most other metal finishing companies, we can reduce our environmental impact and keep our water clean!
