Alluvial Garnet

Alluvial Garnet


Alluvial Garnet has a sub-angular shape, hardness, and high bulk density, making it ideal for quickly removing thin to medium thickness coatings, mill scale, and rust. This lower-dusting abrasive naturally has low chloride levels, reducing surface contamination.

Common Uses:

  • Manufacturing/Maintenance
  • Bridges, pipelines, oil refineries, rail yards
  • Ship yards, storage tanks, water towers
  • Blast Rooms/Blast Yards
