Product Description

Glass beads are tiny spheres of glass that are used in paint and durable road markings to reflect light back to the   driver in dark or poor weather conditions –improving safety and visibility. The glass beads play a very important role in the road safety .During day time the white road marking material gives the sufficient visibility as a contrast to the asphalt. In the night time   contrast of the white line is not sufficient and must be improved by adding light reflective glass beads.
