Sieve Mesh size, which indicates the number of openings per linear inch, or in microns (µm), which measures the particle diameter. 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.

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. Understanding Grit Size Standards The blasting grit size chart operates on a numerical system that can appear counterintuitive to the uninitiated.
Conversely, fine grit produces a shallow, satin finish that is ideal for cosmetic applications where a smooth, non-reflective surface is required but heavy corrosion protection is not. The chart provides the starting point, but the operator must adjust the air supply and machine settings to match the specific grade being used.

Environmental and Safety Considerations. Using a coarse grit at low pressure will result in inefficient cutting, while using fine grit at high pressure can over-clean and warp thin sheet metal.
