Steel Grit

Steel Grit is a general-purpose manufactured abrasive used to remove thick coatings, heavy rust, and mill scale. It's fully angular shape cleans by aggressively cutting away at the surface leaving a uniform surface profile. Steel Grit is most commonly used in abrasive blasting rooms and mobile steel grit recycling systems and is frequently used for bridge, wind tower, and ship and railcar manufacturing and maintenance.

STEEL GRIT complies to SAE specification J1993 and J444 as well as IS 4606 of 1983.
