Highway Safety Marking Spheres

Pavement Markings Shine in the Dark.
Essential Function for the Safety of Night-time Driving.

Some of the excellent features of glass include transparency, resistance to water and chemicals, thermal stability, and hardness. Particularly, when glass is manufactured into spherical particles, it can resist impact and make extremely stable material. Because glass contains non toxic components, and is recyclable, it is expected to be applied to many areas.
