Black Diamond Coal Slag offers enhanced speed and cutting for superior cleaning ability. A larger number of gradations means you can be more confident in achieving your target profile. We have the product to blast through the toughest epoxies and layers of old paint, as well as the finesse to remove light rust and mill scale.  

Coal Slag is a widely used abrasive due to its profiling ability, economical price point, and availability. It is frequently used in new steel and steel maintenance applications, such as blasting of storage tanks, water towers, bridges, ships, structural and plate steel, offshore platforms, and oil field maintenance.
