Cost-effective Blast Cleaning
GMA Garnet™ abrasive is more cost-effective over other abrasives. Compare the cost of your abrasives by using the GMA Calculator or Contact Us to assist you in achieving quality results at lower costs.
Blast cleaning using GMA Garnet™ provides significantly lower dust emissions due to its inherent material toughness and rapid settling (high specific gravity). This ensures minimum disruption and danger to adjoining operations and improves operator visibility and safety.
Very fast cutting is achieved with speed, large number and shape of grains impacting on the surface. The acceleration and speed of a grain in an air stream is a function of the inertia and hence the size of the grain. Smaller grains accelerate much more readily and impart higher impact energy to surfaces resulting in a superior cleaning rate – usually twice the m2/hr of conventional abrasives.
The unique grain size enables many more active grains impacting the surface and greatly reduces abrasive consumption.
Superior Surface Quality
GMA Garnet™ grains clean deep into the cavities and pitted areas down to the bare metal, thoroughly removing all rust, soluble salts and other contaminations. The blasted surface is free of embedment and rogue peaks and troughs. SA3 White Metal is effortlessly achieved. A surface profile of 50 – 75 microns* is also easily achieved along with a much greater number of peaks per unit area.
Improved Health & Safety and the Environment
GMA Garnet™ is non-toxic with no silicosis hazard or risk of contamination from leachable heavy metals or radioactive substances. Disposal volumes are greatly reduced as a result of lower consumption and recyclability.
GMA Garnet™ is suitable for multiple usages and can be recycled 5 times or more* without losing its superior cutting ability. Special garnet recycling systems are available upon request. These add up to natural, clean and cost effective blasting.
