Grade comparison
Why choose F24 over other FEPA sizes?
F24 is often selected as the balance point between very coarse blasting aggression and controlled industrial roughening.
Very coarse blasting
Used where maximum aggression is required for heavy scale or severe contamination removal.
Heavy-duty cleaning and preparation
Ideal for rust removal, coating prep, and coarse abrasive processing with strong productivity and good control.
Finer blasting and finishing
Better suited when the required surface profile is less aggressive or when finer finishing is preferred.
