7. 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 shto 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.
8. Steel Grit Application:
(1)Blast cleaning of cast steel grit:Used for blast cleaning of casting, die casting, forging, sand removal of casting, steel plate, H type steel, steel pipes, other steel structure.
(2)Rust removal of cast steel grit:Rust removal of casting, forging, steel plate, H type steel, steel structure, descaling of forging.
(3)Shot blasting of cast steel grit:Shot blasting of profile steel, ship board, steel board, steel material.
(4)Shot blasting of cast steel:Shot blasting of steel board, profile steel, steel structure.
(5)Pre-treatment of cast steel grit:Pre-treatment of surface, steel board, profile steel, steel structure, before painting.
