Road Marking Glass Microspheres


Road Marking Glass Microspheres 1) Product Function
  Glass Beads for Road Marking or also called Reflective Glass Beads improve the road marking line contrary reflection function. When driving at night, the lamp shines on the marking line with glass bead in it, the ray of lamp is reflected back parallely. So the driver can look at the road clearly and drive safely at night.
