Product Introduction

 1  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 parallelly. So the driver can look at the road clearly and drive safely at night.

 2  Reflective glass beads as the necessary material for the road marking line/ traffic paint, mainly used for road marking line,denoter, and identification for the guardrail out line.
