GC Steel Grit
- Angular when new, this grit rapidly rounds off in use and is particularly suited to descaling applications.
GB Steel Grit
- Although harder than GC Steel Grit, GB also loses its sharp edges during shotblasting and is suited to descaling and surface preparation applications.
GAA Steel Grit
- Remains angular longer than GB, but has longer life than GA. Ideal in surface preparation for etching and descaling. Used in wheel and compressed air equipment.
GA Steel Grit
- Having maximum hardness, GA always remains angular in its operating mix. This steel grit shatters readily yet has a fast, effective, etching action, making it ideal for deep descaling and etched surface requirements. For use mainly with wheel and compressed air equipment.
