Applications:
l Blast cleaning: Used for blast cleaning of casting, die-casting, forging, sand removal of casting, steel plate, H type steel, steel structure.
l Rust removal: Rust removal of casting, forging, steel plate, H type steel, steel structure, descaling of forging.
l Shot blasting: Shot blasting of profile steel, ship board, steel board, and steel material.
l Shot blasting: Shot blasting of steel board, profile steel, steel structure.
l Pre-treatment: Pre-treatment of surface, steel board, profile steel, steel structure, before-painting.
Steel Grit Types:
l GP: Angular when new, this grit rapidly rounds off in use and its particularly suited descaling applications.
l GL: Although it is harder than GP steel grit, it also loses its sharp edges during shot basting and is particularly suited
to descaling and surface preparation applications.
l GH: Having maximum hardness, GH always remains angular in its operating mix. These abrasives 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).
