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.
