Glass beads –JGB M3– sprinkled on the surface of the painted line. It is selected by the roundness and the ratio of bead sizes with good reflection. It is the best choice for road lines in the foggy areas. JGB M3conforms to AASHTO M247 American Standard.

JGB M3 has 2 kinds:

JGB M31 conforms to AASHTO M247 Type I Standard

JGB M32 conform to AASHTO M247 Type 2 Standard

Packing: 25 kg/bag
