Sheeting that meets the AS/NZS 1906.1 Class 1100 is a highly retroreflective sheeting that uses microprismatic cube-corner elements to better reflect the headlights of newer vehicles, compared to the lower ASTM types. It provides greater luminescence for older drivers and, because it’s designed to be effective at wider angles than standard sign sheeting, it helps truck drivers see road signs at greater distances.
Let’s take a closer look at the reasons why it’s time to upgrade to Class 1100 sheeting.
Studies show that, over the years, low-beam headlights have evolved to be less glaring and deliver more light to the road. However, this means they deliver less light to overhead traffic signs and signs on the shoulders of the road. This makes sign performance more important than ever. Upgrade your traffic sign specification from Class 400 high intensity prismatic sheeting to 3M™ Diamond Grade™ DG³ Reflective Sheeting Class 1100 to compensate for the evolution of low-beam headlights.
Signs that use the same sheeting type for both the sign background and lettering provide optimised performance, deliver consistent contrast, and improve legibility by reducing haloing and glare. All of these factors add up to help your signs perform consistently and efficiently and deliver optimum retroreflectivity in a range of conditions.
According to one study, brighter sign sheeting helped reduce the number of crashes by 25-46% (over a three- to six-year period) in locations where the more reflective sheeting was installed.* Class 1100 sheeting is brighter, more reflective and more conspicuous than standard beaded sheeting (or…than lower grade sheeting). This helps drivers see and react to road signs sooner and with greater confidence.

Work zones, large events, and other changes to a roadway can confuse and present a danger to motorists and workers. More visible road signs with retroreflective sheeting and fluorescent colours attract the driver’s attention to recognise and respond to changes in the road.
Our full-cube retroreflective technology is more efficient and reflects more light than the conventional truncated cubes used in many Type IV and Type IX sheeting products. DG³ Reflective Sheeting uses 100% active-area retroreflectors that maximise reflected light, even on signs placed in less than optimal locations.
When installed at the optimal angle, 3M™ Diamond Grade™ DG³ Reflective Sheeting outperforms the competition by delivering the highest luminance to the driver across important sign viewing scenarios:
Help drivers get the information they need to interpret their surroundings and make critical decisions when they need it most. Fabricate signs with sheeting oriented to our recommended 0-degree or 90-degree angles to consistently deliver messages more quickly, effectively, and safely.
This demonstration shows how 3M's microprismatic fluorescent sheeting can significantly improve critical sign visibility during nighttime conditions. The larger cone of retroreflection illustrates how drivers of both large and small vehicles are better served by Diamond Grade DG³ sheeting.
