Product Description

Glass Bead is a unique abrasive that is widely used in processes such asGlass beads for metal surface cleaning and polishing by shot blasting or peening. It is mainly used in sand blasting equipment.

 

Glass beads are made from high quality cullet crushed and sorted. In manufacturing, the cullet is fused into a ball and annealed to eliminate internal stress and prevent breakage



Glass Beads For Road making:
Transparent spherical glass particle, used to provide night visibility for road markings by reflecting the incident headlight beams of a vehicle towards the driver.
Reflecting glass play a crucial role in maintaining visibility of motorist for driving under dim light or bad weather. They are widely used in highway and airport runway and other pavement transportation systems such as zebra crossing in urban traffic road,cut off line,double amber line road marking etc as reflective materials.
