JGB M1 glass beads are used in high-quality reflective road marking paints, conform to BS 6088 British Standard. JGB M1 is selected base on the reflection, roundness and the ratio of bead sizes, suitable to use in the foggy areas and/or the bad weather areas having restricted vision.

JGB M1 has 2 kinds:

JGB M11 conforms to BS 6088A Bristish Standard

JGB M12 conforms to BS 6088B Bristish Standard

Packing: 25kg/bag
