Why Upgrade to 3M™ Diamond Grade™ DG³ Sheeting?

The Difference Between High Intensity Prismatic and Diamond Grade™ Reflective Sheeting.

  • Brighter Signs, Safer Roads. During the day, and especially at night, 3M Diamond Grade DG³ Reflective Sheeting can make a difference by making signage brighter and more visible, giving drivers more time to react. Let’s compare.

    High Intensity Prismatic Sheeting meets middle-grade performance standards and AS/NZS 1906.1 Class 400. 

    Diamond Grade reflective sheeting (DG3) meets AS/NZS 1906.1 Class 1100. This highly reflective sheeting uses 100% efficient full-cube prismatic technology that reflects almost twice the amount of light back to its source as High Intensity Prismatic sheeting.
