Steel grit types:
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.
