Cast Steel angular grit is produced by crushing speciﬁcally heat treated shot pellets. It's behaviour characteristics in service are dependent upon the hardness selection of GC, GB, GAA or GA grit.
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.
