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