Sharper by Design
Steel Grit
Nupon Steel Grit delivers aggressive cutting action for fast, effective surface preparation. Its angular grains are engineered to strip coatings, remove scale, and create strong anchor profiles — giving your projects the sharp edge they demand.
Nupon Steel Grit is an angular, high-carbon abrasive designed for aggressive cutting action and reliable surface profiling. Produced by crushing quenched steel shot, its sharp edges make it ideal for removing scale, rust, paint, and tough coatings.
To match different blasting requirements, Nupon offers three grit types:
GP (Steel Grit – Angular & General Purpose): Gradually rounds during use, offering balanced cleaning and durability.
GL (Steel Grit – Long Life): Retains angular shape longer for consistent cutting performance and extended recyclability.
GH (Steel Grit – High Hardness): Maintains sharp edges and maximum aggressiveness, ideal for tough surfaces and strong profiling.
With controlled hardness, accurate grading, and recyclable durability, Nupon Steel Grit ensures superior efficiency and surface results for industries that demand performance.
