Our garnet

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 process

Innovative processing

Our processing technologies have been developed over 40 years to ensure customers receive industry-leading abrasive performance.

Quality check

Quality control

We systematically test and analyze our garnet against 12 performance areas and seek frequent independent third-party analysis.

Product testing

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%.
