Grit & Shot Blasting

Grit & Shot Blasting is a surface treatment process widely used to clean, strengthen, or polish metal surfaces. It involves propelling abrasive materials such as steel grit or steel shots at high velocity to remove contaminants, rust, or scale, preparing the surface for coating or finishing applications.

At SAI ASSOCIATES, we use advanced blasting equipment and high-quality abrasives to achieve consistent surface finish standards for a variety of industrial components.

Key Features

High Surface Cleanliness

Removes rust, scale, paint, and contaminants to achieve SA 2.5 – SA 3 surface standards.

Improved Coating Adhesion

Enhances coating bonding for longer-lasting paint and corrosion resistance.

Precision & Uniformity

Ensures even blasting results and consistent surface roughness for all components.
