Steel Grit

We have G10, G12, G14, G16, G18, G25, G40, G50, G80, G120, almost all the types of steel grits.

Steel grit is mainly used for the following shot blasting and sand blasting equipment including rotary barrel shot blasting machine, hook type shot blasting machine, pedrail type shot blasting machine, roller type shot blasting machine, table type shot blasting machine, P& F Shot Blasting Machine, trolley type shot blasting machine, abrator equipment, shot peening machine, sandblasting room, steel material pretreatment production line, H steel shot blasting machine, I beam shot blasting machine.

GP: The This grit is angular when it is new. It will be rapidly rounds off in use and its particularly suited descaling applications.
GL: Although it is harder then GP steel grit, it will also lose its sharp edges during shto basting and is particularly suited to descaling and surface preparation applications.
GH: Having maximum hardness, GH grit 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). For use mainly with compressed air equipment.
