Carbon-Steel-Grit
Carbon Steel Grit is a general-purpose manufactured abrasive used to remove thick coatings, heavy rust, and mill scale. It’s angular shape cleans by aggressively cutting away at the surface leaving a uniform surface profile. Carbon Steel Grit’s high bulk density, low friability, consistent sizing, and low dust levels provide superior production rates. Carbon 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.

RECYCLABILITY

The low friability of Carbon Steel Grit allows it to be recycled hundreds of times. Unlike mineral or slag abrasives, Carbon Steel Grit will not completely shatter when it hits a surface, keeping its relative size. Recycling Carbon Steel Grit increases profitability by reducing abrasive consumption, and shipping, cleanup, and disposal costs.

INCREASED PRODUCTION

Carbon Steel Grit’s higher bulk density and high hardness results in more energy being transferred to the work surface than mineral or slag abrasives, easily removing thick coatings, heavy rust, and mill scale. Carbon Steel Grit’s uniform particle size provides consistent coverage and surface finish, increasing production rates.

LOW DUSTING

Carbon Steel Grit’s durability and low friability produce lower dust levels than most mineral or slag abrasives. Low dust levels improve the operator’s visibility of the work surface, increasing production rates. Lower dust levels also reduce cleanup costs on the job site.
