Alluvial Pink Garnet SGA20/40

Garnet is a kind of natural chemical inert non-metallic mineral. Because of its hardness, high density, non-toxic, low dust and other characteristics, it is often widely used in industrial sandblasting, including oil & gas pipeline, ship hull, bridges, steel rust removal, etc.

Alluvial Pink Garnet SGA20/40 is produced by repeated collision and friction under the action of water for a long time in a natural state. Its surface has a certain smoothness.

Coarse grains are suitable for heavily rusted surfaces. 20/40 mesh garnet can effectively remove the rust and coatings of ship hull, bridge steel frame and marine industry. Large particles ensure sandblasting efficiency and cleaning results.

Due to its high density with stronger impact force, garnet can better clean the metal surface. It also can be reusable many times and is an ideal substitute for other sand blasting media.
