Comparing 3M™ Type IV and Type XI sheeting

Differences between High Intensity Prismatic and Diamond Grade™ reflective sheeting

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

    High Intensity Prismatic Sheeting meets middle grade performance standards and ASTM D4956 Type IV. This reflective sheeting uses polycarbonate cube corner technology and is often used for reflective traffic and road signs.

  • Diamond Grade DG³

    Diamond Grade DG³ reflective sheeting meets ASTM D4956 Type XI. 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.

  • *Warranty on fluorescent color is up to 10 years and may vary by location. Check with your 3M representative for complete warranty information.
