Glass Beads

Throughout the world, roads are much safer today due to the use of small, spherically shaped glass beads which are added to the freshly striped highway lines as they are applied. Only with glass beads the stripings become visible at night. This phenomenon is called retroreflection.

SWARCO has been manufacturing these highly retroreflective glass beads for almost 40 years. Swarco's quality management system and pure raw materials ensure that SWARCO glass microspheres are very consistent with regard to their chemical and physical properties.
