Glass Beads

Small Beads, Great Effect

SWARCO has been manufacturing reflective glass beads for road markings since 1969. There have been drastic changes in mobility over those five decades. Having said that, the vision we had back then is more true now than ever. Ensuring safety and comfort for all road users is fundamental to every road around the world.

Each Bead is unique

The Combinations are varied and individual

There are different types of reflective glass beads. Our smallest micro glass beads only measure a few thousandths of a millimeter, while the maximum diameter is 2 millimeters. Our product range consists of five different types of beads to satisfy all requirements.

Our Glass Beads

The next generation of glass beads.

Our high-performance glass beads, SWARCO SOLIDPLUS achieve excellent retroreflection values of over 1000 mcd/m2*lx.

Even after several years of traffic exposure the required standard values get significantly exceeded. Suitable for all road marking materials.
