Performance at GMA
At GMA, performance means more than speed — it’s ensuring our garnet abrasives deliver exceptional results on every job.
We are committed to reliably delivering products engineered to add value with industry-leading speed, surface quality, consumption, and reduced environmental and safety risks. GMA Garnet™ gives you the performance edge you need every day on the job.
The GMA advantage
GMA Garnet™ is a natural mineral that outperforms other abrasives due to its unique hardness, toughness, density, and angularity. When used with the recommended equipment, it enables high productivity and lower abrasive consumption.
World-class abrasive development
Innovative processing
Our processing technologies have been developed over 40 years to ensure customers receive industry-leading abrasive performance.
Quality control
We systematically test and analyze our garnet against 12 performance areas and seek frequent independent third-party analysis.
Product testing
Leading independent suppliers continually test our products in-field against performance benchmarks, ensuring maximum customer benefit.
Next-generation engineered blends
For over 40 years, we have led innovation in industrial garnet by maximizing its natural performance advantages.
GMA’s engineered blend abrasives range is made from a distinct combination of coarse and fine garnet grains (in some cases, both alluvial and hard crushed rock garnet) engineered for specific purposes — not just to meet traditional mesh sizes. The high performance and reduced abrasive consumption often lead to total project savings of up to 30%.
Unlock performance with our technical expertise
GMA’s technical specialists are from the abrasive blasting and waterjet cutting industries and have extensive knowledge in maximizing productivity onsite.
We strive to help customers achieve higher productivity and lower abrasive consumption to save on overall project or job costs. From selecting the right products to ongoing education and support, our team is here to assist.
