Glass Beads Powder
Glass Granule is an angular, iron-free, reusable blasting medium for stainless steel and aluminum. The angular shape of glass particles is more abrasive to blasted surfaces than glass beads because they are not as hard, so glass particles are not as aggressive as aluminum oxide.

– Pressure blast systems
– Injection blast cabinets
– Cleaning metallic surfaces with removal of material (abrasive effect)
– Removing rust and scale from metallic surfaces
– Removing tempering colour
Surface finishing:
– Creating a matt finish on surfaces
– Producing specific visual effects
Other:
– Roughening metallic surfaces
– Creating a matt finish on glass
– Deburring
– Processing very hard components
