Staurolite is a general-purpose mined mineral abrasive used to remove thin coatings, rust, and mill scale. Its sub-angular shape is ideal for applications where a minimal surface profile is required. Staurolite is excellent for achieving a near white finish and is commonly used for new steel applications; including storage tank & tower construction, structural & plate steel blasting, and steel fabrication.

Common Uses:

  • Manufacturing/Maintenance, bridges, blast rooms
  • Pipelines, oil refineries, rail yards, ship yards
  • Storage tanks, water towers, blast yards
