3M™ Diamond Grade™ DG³ Reflective Sheeting

  • To help ensure road safety, we must consistently and effectively provide drivers with critical information and visual cues—particularly at night. This starts with bright, highly retroreflective road signs. 3M™ Diamond Grade™ DG³ Reflective Sheeting uses advanced technology to meet—and exceed—the requirements for ASTM Type XI sheeting, setting the standard for sign performance.

Why ASTM Type XI Sign Sheeting?

Sheeting that meets the ASTM Type XI standard 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 it’s time to upgrade to Type XI sheeting.

  • A car’s headlights illuminate falling snow on a road at dusk.
    Low-beam Headlights Are Evolving

    Studies show that, over the years, low-beam headlights have evolved to be less glaring and deliver more light to the road. But 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 Type IV high intensity prismatic sheeting to 3M™ Diamond Grade™ DG³ Reflective Sheeting Type XI to compensate for the evolution of low-beam headlights.

  • A large highway sign is highly visible over a busy highway.
    Standardized Sheeting Ensures Sign Performance

    Signs that use the same sheeting type for both the sign background and lettering provide optimized 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.

  • Cars speed past illuminated road signs on a highway at sunset.
    Visible Signs Improve Road Safety

    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.* Type XI 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.

See why it may cost less than you think and save you money in the long run when you upgrade your signs to our 3M™ Diamond Grade™ DG³ Reflective Sheeting.

LET'S DO THE MATH.

  • Vehicle taillights speed past temporary work zones at night

    Positive guidance is no accident in work zones.

    Work zones, large events and other changes to a roadway can cause confusion and present a danger to motorists and workers.  More visible road signs with retroreflective sheeting and fluorescent colors attract the driver’s attention to recognize and respond to changes in the road.

  • Highway signs are highly reflective over a dark road at nighttime.
    Maximize Reflected Light

    3M’s 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 maximize reflected light, even on signs placed in less than optimal locations.

  • Vehicles speed past a reflective exit sign on the highway.
    Install the Brightest Full-Cube Sheeting

    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:
     

    • 27% brighter for overhead signs and signs on the left shoulder
    • 30% brighter for signs on the right shoulder
  • 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.
