This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
