What does sandblasting do, and what is glass beading?
Sandblasting etches the surface of the metal, creating a solid mechanical bond adhesion during the curing process. It also cleanses the metal. We use very fine angular aluminum oxide media because it gives the best results for powder coating adhesion. Picture in your mind that they type of etch this media leaves behind would be similar to sharp peaks (hills) and valleys. Glass beading uses a round glass media that pocks the surface other than impinging the surface. This kind of media is used more for aesthetic purposes than functional uses. Glass bead media does not provide the best anchor tooth for best powder coating adhesion. Glass beading a surface (especially aluminum) reflects the light to your eyes better, and makes metal appear whiter or brighter.
