BEADS FOR EVERY REFLECTIVE NEED

Road marking visibility at night can only be achieved by the application of tiny glass beads on to the surface and incorporated within road marking materials. These beads ( Safety Marking Spheres ) are manufactured in a full range of sizes and offer life and durability to thermoplastic road markings.

BEAD GRADATION

Glass beads are graded in precise size ranges to optimize reflective performance throughout the life of the line. As markings wear under traffic flow, some spheres are dislodged allowing previously covered spheres to become exposed and act as reflective elements.

DEGREE OF EMBEDMENT

Maximum reflectivity of individual glass spheres occurs when the optinmum degree of embedment is achieved. This occurs when 60% of the bead is below the surface of the pavement marking material and 40% is above.

ROUNDNESS

Optimum retro – reflection requires true round spheres. Non round spheres do not reflect light efficiently but scatter it in random directions. Strict quality control is necessary to ensure correct amounts of true round spheres.
