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 stripping become visible at night. This
phenomenon is called retro-reflection. SWARCO has been
manufacturing highly retro-reflective glass beads for almost 30
years now. ISO 9001:2000-certified production processes and pure
raw materials ensure that SWARCO glass micro-spheres are very
consistent with regard to their chemical and physical
properties. |
