Manufacturer of metal and abrasive products. Selection includes metallic, pressure blast and sandblast abrasives, counterweights, grit, shot, scrap metal and alox. In March of 1982, General Metal and Abrasive Company was incorporated to service the metal working industry in recovery and reclamation of steel abrasives; cast steel shot, grit & cut wire shot. Our primary customers performed abrasive blasting for surface cleaning and/or preparation & shot peening. Working out of a 10,000-square-foot building in Detroit, the company quickly earned a reputation for providing exceptional customer service, effective cost saving along with offering top quality products. Continued growth created a need for additional space. In March 1986, General Metal and Abrasive Company moved into a new 26,000-square-foot facility on 4.5 acres in Romulus, Michigan. Close to two major interstate highways, the new location also offered room for additional expansion. In 1989, the company installed a new production line to recycle and recover Brown Fused Aluminum Oxide. Soon after, the current management team assumed ownership of the company and the name was changed officially to GMA Industries in recognition of its continued diversification. As business activity increased, the company built a 10,000-square-foot addition to the existing plant structure to warehouse both raw and finished product. In 2011, another 12,000 square feet of warehouse and processing space was secured close by. In 2003, GMA Industries entered into a business relationship with Ervin Industries, representing a new and unique abrasive media called NU-SOFT Steel Shot, which allowed the blast cleaning of soft, delicate parts without worry of damaging the surface, changing the surface profile or harming threaded or machined surfaces. This business relationship with Ervin Industries was expanded in 2012 when GMA Industries was named the Southeast Michigan Distributor for Ervin’s Amasteel Cast Steel Shot & Grit and Amacast Cast Stainless Steel Shot. In 2004, GMA began producing our own Virgin Brown Fused Aluminum Oxide. This product is called V-Blast, the “V” standing for “Virgin” and goes along with our R-blast, the “R” standing for “remanufactured.” Today, GMA is one of the industry’s leading manufacturer and distributor of Virgin and Remanufactured Abrasives and offers a wide assortment of abrasives for shot blasting, shot peening, surface cleaning and preparation.From raw material through finished production, the GMA Quality Control Program ensures that GMA products meet or exceed industry standards and customer expectations. A Quality Control Manager is on duty at all times in our testing laboratory, where random samples of product are collected and tested throughout production. Every step of the process is monitored to ensure the product is clean, sized according to specifications, packaged neatly and labeled properly.

Since 1982, GMA has been an innovator in the recovery of abrasive media, offering economical and environmentally sound options. GMA Industries has developed a recycling and reuse process for abrasives that not ONLY helps protect the environment, but also provides significant cost-savings for customers. GMA Industries is the ONLY abrasive media source to offer a Full Abrasive Recycling Service for both Virgin and Recycled Materials.GMA Industries’ Vacuum Acquisition Service Program (VASP) can be beneficial even to the smallest of companies.
