Bead Blast

Definition and Function

Bead Blast is a surface treatment process in which glass beads or similar spherical media are propelled at high speed onto the surface of metals or other materials, creating a uniform fine texture and matte finish.
Removes surface oxides, burrs, and minor scratches.
Improves surface adhesion for subsequent coatings, anodizing, or painting.
Enhances wear resistance and tactile feel.
Provides a uniform matte or matte bead-textured appearance.

Colors

Matte Silver-Gray

The blasting itself does not alter the base material color; the surface usually appears uniform matte silver-gray or the original material color with a matte finish.

Different colors can be achieved through subsequent treatments, such as anodizing, chemical coloring, or painting.
