SWARCO DURALUX

The next generation of glass beads

Our guiding principle

As a premium reflective glass-bead product, SWARCO DURALUX is particularly durable, simple to apply, and ensures increased road safety thanks to its exceptional retroreflection.

Our vision

SWARCO DURALUX sets the economical and technical benchmark worldwide for the next generation of reflective glass beads, with maximum performance in wet and dry conditions.

Our values

Innovation, Sustainability, Reliability

Our motto

SWARCO DURALUX                                                                                                             The next generation of glass beads

The unique glass formulation combined with a state of the art beading process SWARCO DURALUX is the result of many years of research and development – an innovation from the SWARCO Road Marking Systems Division’s Competence Center for Glass Technology and Marking Systems.

Excellent retroreflection

Higher retroreflection means lower accident risk

The study “Investigation of longitudinal pavement marking retro reflectivity and safety” (Carlson, Park & Kang, 2013) verifies that every 100 mcd /m²*lx increase in retroreflection reduces the risk of accidents by up to 8.6 percent.


The SWARCO DURALUX bead brings the results of this study to the road. Thanks to its excellent retroreflectivity, this bead substantially increases road safety and can save lives. Particularly at night and in foggy or rainy weather, road markings can be
seen much more clearly – precisely when they are most important to road users! The reflectivity (RL value) of SWARCO DURALUX is outstanding.

The chart proves impressively that the reflectivity of SWARCO DURALUX beads far surpasses even the strictest requirements of EN 1436 Class R5 over a period of 28 months. A first measurement was carried out one month after marking with SWARCO DURALUX beads. Further tests were performed after eight months, 14 months, and 28 months. They show clearly that the SWARCO DURALUX bead still has excellent retroreflection values even after several winters.

Very durable

SWARCO DURALUX

SWARCO DURALUX impresses also in the abrasion test. This test was conducted on a rotating machine with three different bead types under identical conditions.


SWARCO DURALUX beads are not only more durable than standard and high- index beads, but also measurably more durable. SWARCO DURALUX beads therefore
not only increase the safety of road users over a longer period, but also offer clear economic benefits.


The test also shows that SWARCO DURALUX beads have practically no defects, flaking, or signs of wear. All factors that underline the exceptional durability of
SWARCO DURALUX beads. They are far tougher than other bead types.

Roadmarking professionals can be certain that they will achieve the required values, and sustainably increase road safety thanks to the higher retro reflection.
