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 ASTM D4956 Type IV. This reflective sheeting uses polycarbonate cube-corner technology and is often used for reflective traffic and road signs.
Diamond Grade reflective sheeting (DG3) 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.
According to one study, over a three to six-year period, crash numbers dropped by 25 to 46 per cent where brighter signs, like those with DG³ sheeting, were installed.¹
Help improve the visibility and effectiveness of traffic signs.
Full cube technology reflect light at broad observations angle, helping drivers in all vehicle sizes see your sign.
