Our Glass Beads for Road Marking use the window glass, and the color is white and clean; reflective micro glass beads will give good performance when used on marking line, the roundness is more than 80%, to promise the reflectivity. Glass beads for road marking are widely used on city road lines, highway pavement, and Guardrail outlines.
With many years of experience in the manufacturing of reflective road paint beads, We have mature solutions of glass beads for paint, such as Inter-mix glass beads, Drop-on glass beads, High index reflective glass beads. The national standard of GT, BS6088, EN1424/1423, and AASHTO guarantee our glass beads’ quality for road marking.
