Shot blasting is an industrial surface treatment process that utilizes high-velocity propelled metallic particles, often called "shot," to clean, profile, and smooth metal surfaces by removing contaminants like rust, old paint, casting residues, and other debris, effectively preparing them for further finishing like coating or painting, while also enhancing the adhesion of these applied materials; this process is commonly used in industries like automotive, aerospace, shipbuilding, and construction due to its ability to improve the durability and lifespan of metal components by creating a clean, uniform surface texture through the forceful impact of the abrasive media against the material.
