Media for Blasting and Cleaning - Steel Grit

Steel grit from Composition Materials is available in four grades of hardness. This aggressive media is suitable for blasting and stripping foundry metals and steel.

Steel grit also effectively creates an etching on hard metals for improved adhesion of coatings such as enamel, paints, rubber, and epoxy.

Applications include blasting bridges, removal of flashing, metal parts, rail car reconditioning, and forging industry applications.
