G10 / G12 Steel Grit is a coarse steel grit abrasive series designed for heavy-duty blasting and aggressive surface preparation. With large particle size, sharp angular shape and strong cutting power, G10 and G12 steel grit can effectively remove heavy rust, thick oxide scale, mill scale, old coatings and severe surface contamination from metal surfaces.
G10 steel grit is a very coarse steel grit size with stronger impact force and deeper surface profiling ability. It is suitable for extremely heavy-duty cleaning applications, such as large steel structures, thick steel plates, heavy castings, shipbuilding components and workpieces requiring a deep anchor profile before protective coating.
G12 steel grit is also a coarse steel grit abrasive used for heavy-duty blasting and surface preparation. Compared with G10, it provides strong cutting performance with slightly more controlled surface profiling, making it suitable for large steel structures, bridge components, shipbuilding, tank manufacturing, heavy castings and industrial surfaces that require effective rust removal and coating preparation.
G10 / G12 Steel Grit is widely used in steel fabrication, foundries, shipbuilding, bridge construction, tank manufacturing, machinery manufacturing and heavy industrial surface treatment. These steel grit sizes are recommended for applications requiring powerful cleaning performance, deep surface roughness and strong mechanical adhesion before painting, anti-corrosion coating or protective coating.
Steel grit is produced by melting high-quality steel, atomizing it into steel shot, crushing the shot into angular particles, and then screening and heat-treating the material according to required hardness and size.
During production, the steel grit is classified by sieve analysis and inspected for chemical composition, hardness, density and particle size distribution. This helps ensure stable cutting performance and consistent surface roughness during blasting.

G10 / G12 Steel Grit has a coarse particle size and sharp angular shape, providing strong cutting power for heavy-duty blasting. It can effectively remove heavy rust, thick mill scale, oxide scale, old coatings and severe surface contamination from steel surfaces.
Compared with finer steel grit, G10 and G12 can create a deeper surface profile on metal surfaces. This helps improve mechanical adhesion between the substrate and protective coating, making them suitable for anti-corrosion coating, heavy-duty painting and surface preparation before coating.
G10 / G12 Steel Grit is suitable for large and heavy metal workpieces that require fast and aggressive surface cleaning. It helps improve blasting efficiency on large steel structures, thick steel plates, heavy castings, shipbuilding parts, bridge components and industrial equipment.
For workpieces with heavy rust, thick oxide scale, old coating layers or strong surface contamination, G10 and G12 steel grit provide more aggressive cleaning performance than medium or fine grit sizes. They are especially suitable for demanding surface preparation projects.G10 / G12 Steel Grit is widely used for heavy-duty blasting, aggressive surface preparation and deep surface profiling. With coarse particle size and strong cutting power, these steel grit sizes are suitable for applications that require powerful rust removal, thick scale removal and surface preparation before protective coating.

G12 steel grit is a coarse angular abrasive used for heavy-duty blasting and strong surface preparation. It provides aggressive cutting action and is suitable for removing heavy rust, thick oxide scale, old coatings, mill scale and strong surface contamination.
G12 steel grit is commonly used for steel structures, shipbuilding, thick steel plates, large castings, heavy machinery parts and metal surfaces that require a rough surface profile before painting or protective coating.
G12 steel grit can create a deep and rough surface profile because of its coarse particle size and sharp angular shape. Compared with steel shot, steel grit produces a stronger cutting effect and a rougher anchor pattern, which helps improve coating adhesion.
It is suitable for heavy surface preparation, especially when the workpiece needs strong cleaning power and a rough surface before anti-corrosion coating, painting or further processing.
