Steel Grit Types:

GP: Angular when new, this grit rapidly rounds off in use and its particularly suited descaling applications.

GL: Although harder then GP steel grit, also loses its sharp edges during shot basting and is particularly suited to descaling and

surface preparation applications.

 GH: Having maximum hardness, GH always remains angular in its operating mix. These abrasive are particularly effective in

surface treatment processes and produce a uniform, etched finish, GH angular grit should only be used in wheel machines where working requirements take precedence over cost price considerations (for example with rolling mill cylinders or when a special finish is needed). For use mainly with compressed air equipment

Applications:

Blast cleaning: Used for blast cleaning of casting, die-casting, forging, sand removal of casting, steel plate, H type steel, steel

structure.
 Rust removal: Rust removal of casting, forging, steel plate, H type steel, steel structure, descaling of forging.
 Shot blasting: Shot blasting of profile steel, ship board, steel board, and steel material.
 Shot blasting: Shot blasting of steel board, profile steel, steel structure.
 Pre-treatment: Pre-treatment of surface, steel board, profile steel, steel structure, before-painting.
