Glass Beads Description

High reflective glass beads, also known as retroreflective glass beads, are small spherical beads that are used in road markings to enhance visibility and improve safety.

The main purpose of using high reflective glass beads in road markings is to increase the visibility of road signs, lane markings, and other pavement markings, especially during nighttime and wet conditions.
