NOKIN 8 glass beads aluminum road studs work on the principle of spherical retroreflection: when a beam of light hits the retroreflective optical system, it is reflected back to its starting point, regardless of the direction from which the beam hits the reflector.
The shape of the glass beads is precisely calculated by a computer to achieve the best reflection effect. The back of the glass element is coated with a high-reflectivity silver mirror layer and multiple special protective layers.
Because the reflector is subject to great mechanical stress from the vehicle, its surface must be as strong and durable as possible. Glass is the best material to withstand such loads.
Depending on the application, the glass beads can be embedded in a variety of plastics. These plastics have their own unique properties and are very suitable for outdoor use.
The combination of glass beads and high-quality aluminum materials makes it an extremely long product life, which is unmatched by other technologies.
International studies have shown that cat eye road studs are the best way for drivers to discern the direction of the lane in dark or bad weather conditions. They appeal to three different human senses because they are visible, audible, and can be felt due to the bumpy effect caused by driving. When visibility is low, motorway cat eye road studs provide you with the best lane guidance. 85% of driving information comes from visibility. Visibility affects reaction time. The better the visibility, the quicker you can spot obstacles. NOKIN road stud reflectors provide the best visibility.
What do the reflective road studs of different colors mean on the road?
-White reflective lane markers: mark the lanes or the middle of the road.
-Red reflective lane markers: mark the left edge of the road.
-Motorway reflective lane markers: mark the central reservation of a dual carriageway or motorway.
-Green reflective lane markers: mark the edge of the main carriageway at lay-bys and slip roads.
-Green/yellow reflective lane markers: indicate temporary adjustments to lane layouts, e.g. where road works are taking place.
