    Productivity

    High productivity

    Achieve your specified surface profile faster than alternate abrasives.

    Costs

    Low consumption

    Complete the job with far less abrasive, reducing costs in abrasive purchase, transport, and disposal.

    High Peak Density

    High peak density

    Generate higher peak density over alternate abrasives for unmatched coating adhesion and integrity.

    Surface quality

    Low embedment

    60% of the average slag-blasted surface is embedded with residual abrasive. Garnet results in minimal embedment.

    Hazard mask

    Low dust

    GMA Garnet™ offers the closest thing to dustless blasting, drastically improving operator visibility and reducing site contamination.

    Safety

    Low safety risk

    Garnet is an inert mineral with little to no heavy metals creating worker risks or environmental hazards.

    CASE STUDY

    A week's work in one day with GMA NewSteel™

    When project timelines tightened, a leading industrial coatings contractor unlocked 71% more productivity than waste slag — at 15% less cost.

    Fabrication

    GMA Garnet™ is ideally suited to structural steel fabrication yards where new construction and maintenance projects require hard mill scale removal. GMA NewSteel™ is the fastest cleaning mineral abrasive on the market for removing mill scale.
    • Exceptional surface cleanliness with minimal abrasive embedment, for better corrosion resistance and substrate integrity
    • High blasting and cleaning efficiency, leading to low abrasive consumption, minimizing usage and maximizing recycling.
    • Very low dust emissions, reducing risk to surrounding sensitive equipment
    • With the right equipment GMA Garnet™ can provide a high level of reusability through recycling onsite
    • GMA Garnet™ is an inert, sustainable natural mineral, with little to no recordable heavy metals and worker hazard risks

    Powder Coating

    GMA’s finer grade garnet abrasives such as GMA NewSteel™ and GMA PrecisionBlast™ are uniquely positioned for the powder coating industry, able to produce the ideal exceptionally clean surface, with uniform profile and peak density, allowing for maximum coating adhesion and integrity.
    • Exceptional surface cleanliness with minimal abrasive embedment allows for better corrosion resistance and substrate integrity
    • Creates the required surface profile with consistent peak density for stronger coating adhesion
    • High blasting and cleaning efficiency, leading to low abrasive consumption
    • Very low dust emissions, reducing risk to workers and contamination to surrounding areas

    Precast Concrete

    Perfect concrete finishing starts with GMA Garnet™. The unique blasting technique used on concrete to produce the desired texture and to expose the aggregate beneath for an architectural decorative finish is achieved via a cost effective blend of GMA Garnet™ and pyroxene.
    • Very low dust emissions, allowing for productive efficiency in projects and reducing emissions in the surrounding environment
    • High blasting efficiency, leading to lower abrasive consumption reducing blasting time and abrasive disposal
    • Waste management and garnet recycling: With the right equipment GMA can provide a high level of reusability through recycling onsite
    • GMA Garnet™ is an inert, sustainable natural mineral with little to no recordable heavy metals or worker risks & hazards.
