Commitment to achieving the best possible traffic safety outcomes starts with 3M™ Diamond Grade™ DG³ Sheeting. It provides brightness and visibility with the highest optical efficiency of 3M's sheeting products by returning more light to drivers in a range of vehicle types.
3M’s “full-cube” retroreflective technology greatly increases the visibility of road signs for drivers across a range of vehicle types and sign geometries. These performance improvements are enabled by “100% active area” full cube retroreflectors that result in higher efficiency sheeting as compared to conventional retroreflective sheeting. Even signs in the most disadvantaged locations perform better with Diamond Grade DG³ sheeting.
58% Retroreflection efficiency (29% + 29%) is ideal for large and small vehicles. Increasing the overall total retroreflective efficiency serves the greatest segment of nighttime drivers of all vehicle types.²
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 maximise reflected light, even on signs placed in less than optimal locations.
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.

Watch our demonstration videos to see for yourself the advantages of choosing Diamond Grade DG³ reflective sign sheeting.
This demonstration shows how 3M's microprismatic fluorescent sheeting can significantly improve critical sign visibility during nighttime conditions. The larger cone of retroreflection illustrates how drivers of both large and small vehicles are better served by Diamond Grade DG³ sheeting.

With its life expectancy of 12 years, Diamond Grade DG³ provides protection longer than 3M's lower-grade sign sheeting.
Brighter signs give drivers more time to react. During the day, and especially at night, DG³ Reflective Sheeting can make a difference by making signage brighter and more visible as compared to our High Intensity Prismatic sheeting, giving drivers more time to react.
Brighter sheeting is more visible to drivers and has been shown to increase safety by helping cut nighttime accidents by 25 to 46 percent.¹
"With the highest brightness and retroreflectivity ratings in the industry, Diamond Grade DG³ can safely lower installed road lighting costs by up to $150,000 per km, and annual lighting maintenance by up to $15,000 per km."

With its life expectancy of 12 years, it provides protection longer than lower-grade sign sheeting. It may also require less maintenance and reduce energy expenses.
Brighter Signs, Safer Roads. During the day, and especially at night, 3M Diamond Grade DG³ reflective sign sheeting can make a difference by making signage brighter and more visible, giving drivers more time to react.
High Intensity Prismatic Sheeting meets middle grade performance standards and EN 12899-1 Class RA2. This reflective sign sheeting uses polycarbonate cube corner technology and is often used for reflective traffic and road signs.
Diamond Grade reflective sheeting DG³ meets Class RA3 and R3B of DIN 67520 and Class R3C-UK of UK National Annex to EN 12899-1. This highly reflective sign sheeting uses efficient full-cube prismatic technology that reflects more light back to its source than High Intensity Prismatic sheeting.
According to one study, over a three to six-year period, crash numbers dropped by 25 to 46 percent where brighter signs, like those with DG³ reflective sign sheeting, were installed.²
Road Signs can make a difference during the day, and especially at night, by using 3M™ Diamond™ Grade DG3 Reflective Sheeting.
Significantly brighter signs are manufactured with 3M’s Full Cube Technology. This represents optimal performance in retroreflective technology, with optic elements that are nearly 100% efficient, resulting in sign sheeting that returns almost 60% of available light. Signs are noticeably brighter and more legible at a greater distance. 12-year life expectancy backed by our 3M warranty.
Full cube technology reflect light at broad observations angle, helping drivers in all vehicle sizes see your sign.
