FT. of facilities it now takes to house our present operations in Saint Louis, Microfinish has grown dramatically to meet the needs of our customers. More than 450 customers throughout the Midwest and around the nation count on Microfinish for quality metal finishing and personalized service. We supply coatings to five different automotive companies, as well as leaders in the heavy equipment, electrical, lawn care, appliance, and communication industries.

No matter if an order consists of one piece or one million pieces, each order is given the highest attention to detail and quality finish.  With our ISO 9001:2015 certification, Microfinish has expertise in every facet of finishing that our customers rely on from a metal finishing company.  Combined with years of high quality work in a variety of industries, we’re known for our on-time delivery of parts that are expertly processed with finishing, plating, and St. Louis industrial powder coating services.


Our extensive experience as a metal finishing company can be traced back to its founding in 1959.  Back then, the company’s one shop tumbled stamping to remove burrs and to smooth the surface of parts, thus improving their “Microfinish” (hence the name of the company). Microfinish developed as a complete metal finishing services company further with our entry into zinc plating and our relocation to a larger location in Berkeley. To accommodate increased customer demand for high quality finishing services, our facility has expanded from the original 4,500 square feet a total of three times.  Today the building offers 20,000 square feet which houses two automated lines and one barrel zinc plating line.

Recent Notable Milestones
