Steel Grit G18 is a medium-sized grit that is commonly used for surface preparation, cleaning, and surface finishing in various industries such as automotive, aerospace, construction, and manufacturing. It is typically made from high-quality cast steel that has been crushed, screened, and heat-treated to increase its hardness and durability. Steel Grit G18 is suitable for applications where a medium to coarse surface profile is required, such as removing paint, rust, or corrosion from metal surfaces or preparing surfaces for coating or bonding.
