Glass beads are widely used in road marking systems to improve visibility, especially at night. Their spherical shape and optical properties allow them to reflect vehicle headlights back toward the driver, creating retroreflection.

Size: Glass beads are available in various sizes, typically from 125 to 710 micrometers, depending on the application.

Composition: Mainly silica-based, with the composition influencing transparency, durability, and optical performance.

Surface Quality: Smooth, clean, and well-formed beads provide better light reflection and consistent performance.

Retroreflection: By directing light back toward its source, glass beads make road markings more visible in low-light conditions.

Glass beads are commonly used for roads, highways, runways, and other transportation surfaces, where clear nighttime visibility is essential.
