High-Volume Expendable Abrasive for Outdoor Blasting

Coal slag is the most cost-effective expendable abrasive for large-scale outdoor blasting operations. A byproduct of coal-fired power plants, this angular media delivers excellent cutting speed at a fraction of the cost of garnet or aluminum oxide. Ideal for jobs where media recovery is impractical — bridges, tanks, ships, and structural steel in the field.
