Brighter signs. Safer roads.
  • 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.

    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
  • Highly visible road signs indicate a curve in a mountain road.
    Road sign uniformity: what matters

    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.
