...reflecting roads

We have produced and developed high-quality glass beads for over 160 years and for the last 15 years we have also used ceramic material.

Our quality management to DIN ISO 9001 has been approved for years.

SiLibeads glass beads have been used as reflecting beads in road markings for more than 40 years. The beam from the vehicle lights are reflected back through the glass beads to the driver. There are different categories for road marking requirements. We are specialized using our high quality glass beads type II for wet marking.


The range of sizes of our SiLibeads Type S beads reaches from 0.4mm up to ca. 1.5mm, if required even larger.

The most important advantages of SiLibeads Glass Beads Type S are:

  • High roundness, if required ≥ 95%
  • Smooth and flawless surface and therefore high retro-reflection
  • Neglectable air inclusions
  • All individual sizes to customer specification 0.4-2.0mm
  • More than 40 years of manufacturing experience
  • CE-marking upon request
  • Large storage in Europa
