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. Steel Grit Types: GP: Angular when new, this grit rapidly rounds off in use and its particularly suited descaling applications. 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. 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). Mainly used with compressed air equipment Packing Types:  Braided bag packing, flexible container packing, stock packing, paper bag packing, barrel packing Application Devices:   Steel grit is mainly used for the following equipments including rotary barrel shot blasting machine, rubber bedrail type shot blasting Machine, car type shot blasting machine, table type shot blasting machine , hook &pendent-chain & step-by-step shot blasting machine, hook type shot blast machine ,roller path type shot blasting machine and steel plate pretreatment production line, steel tube inside and outside shot blasting machine, plank spring ,round spring, crank shaft, connecting rod shot peening machine, aluminum alloy, zinc alloy, stainless steel professional sand surface machine, cylinder block(cylinder cover) professional machine, engineer machinery, automobile industry, motorcy
