Glass Bead

Dear Sirs,

Glass bead is a unique and popular air blasting media widely used for cleaning,conditioning or peening metallic surface.
1-1. Bigger beads clean slower,produce higher peening intensities,
remove larger contaminants, produce higher surface roughness and brighter finishes.
1-2. Smaller beads clean faster,produce lower peening intensities,
removes smaller contaminants,produce lower surface roughness and more matte finish.
