3M™ Marker Series 590
Depressible Reflecting Roadstud
Introduced by 3M in 2007, the 3M Marker Series 590 Depressible Roadstud combines the superior brightness of microprismatic sheeting with all the strength and durability of a depressible roadstud. Reflects 7 times more light back to the driver than is required for a glass beaded roadstud in a straight-on geometry situation.
Application/suitability
The 590 depressible roadstud has been designed to slot neatly into any of the current UK approved metal bases. It’s therefore easy to replace a worn or missing glass beaded depressible stud with a more reflective one - no need for extra tooling or training.
Effective Performance Life
The reflective elements are covered with a self healing protective polyurethane resin coating. This creates a tough barrier which protects against scratches, abrasions and spray from the road. The rubber body is specially formulated to withstand years of exposure in the toughest climates.
Product Construction/Specification
The 3M 590 incorporates reflective lenses made of 3M Diamond Grade™ DG3 reflective sheeting. These are covered with 3M’s self healing protective polyurethane resin coating. The rubber body is specially formulated to resist weathering caused by ozone, ultraviolet rays, sunlight and rapid changes in temperature.
Application Surface
The 590 roadstud is compatible with all current UK Department of Transport approved metal bases. They are therefore suitable for replacing worn studs where the metal housing is already installed, or on new roads where the approved metal housing is sourced separately.
