Road marking glass beads

short description:

Glass beads are used in zebra crossings, double yellow lines and night reflective devices of traffic signs.

Glass beads surface type reflective glass beads and mixed reflective glass beads, surface type reflective glass beads is in the road marking construction coating is not dry, a certain amount of glass beads in the marking surface, by the effect of glass beads themselves force, part of the line into the marking coating, thus enhancing the reflective effect of the road marking. Inner reflective glass beads are suitable for road marking reflective coating, its main use is to use glass beads spherical reflective characteristics, improve the reflective performance of road marking coating. Make the line signs more eye-catching, thus improving the safety of drivers driving at night.
