3M™ Diamond Grade™ DG³ Reflective Sign Sheeting

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.

Outsmart the dark.

Maximum Total Reflected Light

DG³ sheeting has twice the brightness of 3M's lower-grade sign sheeting.

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.

Fluorescent Technology Demonstration

See how the fluorescent technology of DG³ sheeting is transformed from invisible light to visible light.
Stop Sign Visibility Demonstration

Elevated seating positions result in a higher angle relative to headlights. In this demonstration, you'll see how elevated seating positions impact sign visibility and how higher-performing sign sheeting can help.
Laser Light Demonstration

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.
Sign Sheeting Performance Comparison

The demonstration in this video shows how 3M DG³ Reflective Sheeting compares to Engineer Grade sheeting and High Intensity Prismatic Sheeting.

Additional Benefits of 3M™ Diamond Grade™ DG³

With its life expectancy of 12 years, Diamond Grade DG³ provides protection longer than 3M's lower-grade sign sheeting.

Increased reactivity time for drivers

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.*

Can help reduce lighting costs

"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."

Long-lasting and less maintenance cost

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.
