3M Reflectivity Levels
In daylight, the three sheeting grades look nearly identical. At night, under headlights, the difference is dramatic. The photo above shows engineer grade on the left, high intensity prismatic in the center, and diamond grade on the right.
Which grade you need depends on the sign and where it’s going:
Engineer Grade Prismatic (ASTM Type I)
Our lowest-cost option. Best for parking lots, private property, and low-speed areas.
High Intensity Prismatic (ASTM Type IV)
The most common choice for public roadway signs, and a significant step up in nighttime brightness.
Diamond Grade DG³ (ASTM Type XI)
The brightest sheeting 3M makes. Typically specified for high-speed roads, overhead and guide signs, and high-risk intersections.
If your sign is going on a public right-of-way, check your agency’s specification — most call out an ASTM type or a 3M series number directly.

Outsmart the Dark with 3M Diamond Grade DG3 Reflective Sheeting
Using science to turn black spots into bright spots. Black spots are places where the number of crashes is higher than average. Often the reason for black spots is the physical configuration of the road or intersection, such as:
• Sharp corners in a straight road, concealing oncoming traffic
• Hills or winding roads that limit visibility ahead
• Hidden junctions and intersections
• Poor or concealed warning signs
