Steel Grit G18

Why Steel Grit G18 for Heavy-Duty Blasting

G18 is one of the coarsest grades in the steel grit range. The angular particles cut aggressively on impact, creating a pronounced surface profile essential for thick-film coatings, thermal spray applications, and metalizing. Unlike round steel shot, which peens and cleans, Steel Grit G18 fractures on impact, constantly exposing new sharp edges that maintain a high cutting rate throughout its recyclable life.

This abrasive is widely used in wheel-blast machines and high-pressure air-blast systems where rapid stripping and deep profiling are required. It is particularly effective on structural steel, tank exteriors, ship hulls, and heavy castings. The consistent particle size distribution ensures uniform surface roughness, which is critical for coating adhesion and long-term corrosion protection.

Performance and Recycling

Steel Grit G18 is a durable, recyclable abrasive. In contained blasting environments such as shot blast rooms and wheel-blast cabinets, it can be recovered, cleaned, and reused multiple times before it breaks down beyond its working size. This recyclability lowers the overall abrasive consumption cost per square meter compared to single-use mineral abrasives. Proper dust collection and air-wash separation are recommended to maintain consistent working mix and peak cleaning speed.
