About Us




J.L. DI-COAT CO. derived from an established family business bought in 1980 as a metal finishing business. In 1990 the second generation stepped in and took control.

In the years following, the new management went after chromate conversion and resin impregnation lines to grow the company. Later, also adding ELECTROPOLISHING OF stainless steel to our product line.

Also in the following years, J.L. DI-COAT sought and achieved 9001-2000 ISO certification. Also achieved was a hexavalent free conversion coating called trivalent chromate. And along with that ROHS was achieved. The third generation is already working and looking forward to continuing the business.

We run fully machined parts with care. All parts are handled by hand and inspected that  way. Turn around time is as needed. We can turn around parts same day if needed. We pride ourselves on quality and service. That's what we have to offer and we do it to detail.
