Steel grit

Description

Steel Angular Grit is produced by crushing specifically heat treated shot pellets.  Service characteristics depend upon hardness selection.  GH Steel Grit:  With maximum hardness, stays angular in the mix, does not shatter readily and has a fast, effective, etching action.  Ideal for deep descaling and etched surface requirements.  For use mainly with compressed air equipment.

Application

Ideal for aggressive cleaning applications. Typical applications include preparation of metal surfaces prior to subsequent coating, surface profiling prior to rubber bonding and lining, removal of sand from castings, descaling of bars and strips etc. Industry users include blast/paint contractors, container manufacturers, ship builders, pipeline manufacturers, plant maintenance and steel fabricators.

Advantages of using steel grit

  • The angular nature of steel grit produces an etched surface on metal for superior adhesion of paint, epoxy, enamel, rubber and other coatings.
  • A ton of slag (copper or platinum) generates approximately 28kg of dust, whilst steel abrasive emits a fraction of that, lowering the maintenance requirements of filtration systems when used in blasting rooms that are fitted with extraction systems.
