Steel Grit
Steel Grit is an angular metallic abrasive media designed for aggressive cleaning, descaling, surface profiling, and coating preparation. Its sharp-edged particles provide high cutting power and create an anchor profile suitable for paint, coating, and industrial surface treatment applications.
Product Overview
Steel Grit is produced by crushing high-quality steel shot into angular particles and heat treating it to achieve consistent hardness and durability.
Its angular shape makes it suitable for removing rust, scale, old coating, sand, and other surface contaminants from metal components. It is widely used where a strong surface profile is required before coating or painting.
Strong Cutting Power
Angular particles provide effective rust, scale, and coating removal.
Surface Profile
Creates anchor profile for coating and painting applications.
High Efficiency
Effective cleaning performance for heavy-duty industrial use.
Reliable Performance
Consistent quality and durability for continuous blasting operations.
