JO-MAR Industries Incorporated was established in 1985 by Richard J. Roth and former partner John Parish in Southeast Michigan. John has since retired but maintains good standing with the company. We serve and ship worldwide. JO-MAR Industries has over half a century of experience in the heat induction technology industry. Our mission is simple; efficiency. We strive to be the best, consistently improving our methods and developing new products and techniques which ultimately extend the value of your dollar. We design, repair, and build induction related pieces, which include, but are not limited to, coils, and transformers. We provide preventative maintenance programs, as well as 24-hour emergency services; we are eager to work around the clock to please our customers. We consistently serve numerous big-name recognizable corporations. JO-MAR operates primarily out of a 12,600 sq. ft. facility just outside of Detroit, in Troy, Michigan.
