GMA Blast Garnet

High Performance Garnet Abrasive

GMA garnet abrasive is a high performance blasting abrasive that delivers the most efficient and cost-effective surface preparation on new steel surfaces, light rust or thin coatings.

GMA garnet abrasive is ideally suited for surface preparation in the fabrication industry:

  • Construction of chemical plants, power stations, mining and processing equipment, gas and sewerage plants, desalination and industrial plants.
  • Construction in the building industry and structural steel.
  • Construction and maintenance of containers and tanks, tank trucks and rail tanks, as well as wagons and coaches.
  • Stone building facades and monuments.
  • Stainless Steel.
Unique and Cost-Saving Advantages

Superior cleaning rate – up to twice the performance of conventional abrasives, with more grains per volume (typical 28 million grains per kg) of active abrasive particles impacting the surface at the rate of 20-25m2 per hour.

Low consumption rate of 7-10kg/m2 is easily achieved. GMA garnet is recyclable up to 6-8 times (depending on the application) due to its superior toughness and low friability (7.5-8.0 Mohs). It is possible to reduce garnet consumption by 70% via recycling.

SA3 white metal is effortlessly achieved. The shape and size of the grains ensure an even surface profile of 45-55 microns at 100psi at the blast nozzle.
