About Us

Driven by innovation. Engineered to perform.

GMA has a proud history of delivering unmatched performance and reliability to our customers, continually pushing the boundaries of industrial garnet abrasives.

Our commitment to excellence

Over the past 40 years, we have driven innovation in industrial garnet to better serve our customers in the abrasive blasting and waterjet cutting industries.

Since being founded in 1983 in Port Gregory — a small coastal town in Western Australia — we have grown to be the only industrial garnet supplier to manage the complete supply chain from the source to processing, international distribution, and recycling. We have a long history of sustainable mining and continue to invest in research and development, focusing on energy-efficient processing and reductions in landfill.

The spirit of innovation has driven a focus on delivering industry-leading performance and reliability for our customers. Our geologists, plant engineers, and lab technicians pursue new concepts and apply new processes and technologies to provide the best-performing, most reliable abrasives. On the ground, our team of sales and technical experts work closely with customers and industry bodies to address their priorities and challenges.

Having organizations rely on GMA is a responsibility we don’t take lightly. As we forge ahead, GMA will continue to push the boundaries of what is possible.
