Steel Grit Selection:

GP steel grit : External form is round and shaped with steel water, owns fine elasticity and the strength of fatigue resistance as a result of fine heat treatment, applied in all aspects, special hardness steel shot applied in strengthening treatment.

GL steel grit : Although harder than GP steel grit, GL also loses its sharp edges during shot blasting and is particularly suited to descaling and surface preparation applications.

GH steel grit : 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 use mainly with compressed air blasting equipment.
