Coarse grit creates a deep, rugged profile known as a "tooth," which provides a strong mechanical bond for protective coatings like epoxy or zinc. Fine Grit (80–120 Mesh): Used for final cleaning and light surface refinement, suitable for achieving a smooth finish on delicate substrates or preparing surfaces for high-gloss paints.

While grit (such as aluminum oxide or silicon carbide) has sharp edges that cut into the surface for aggressive cleaning, steel shot relies on deformation to create a peened, hardened surface. Therefore, a 60-grit product is significantly coarser and more aggressive than an 80-grit product.
Impact on Surface Profile Surface profile is the texture or roughness left on a substrate after blasting, and it is directly dictated by the blasting grit size chart. Softer materials, like brass or soft metals, require a harder grit (such as chilled iron or copper slag) to maintain cutting efficiency without disintegrating too quickly.

The grit size chart must be cross-referenced with the material compatibility chart to avoid using a grit that shatters prematurely or damages the substrate through excessive aggression. Coarse Grit (10–30 Mesh): Reserved for heavy-duty operations such as stripping thick rust, mill scale, or old industrial coatings from steel beams and structural metal.
