Diamond Grade (DG) Reflective Signs
Our premium, ultra-bright option for high-speed highways and critical safety zones. Engineered with full-cube microprismatic technology (Type XI), these signs deliver 12-year all-weather durability and ASTM D4956/MUTCD compliance. Ideal for interstate guides, overhead signage, school zones, and pedestrian crossings.
Diamond Grade (DG) Reflective Signs: The Ultimate in Road Safety
When visibility is non-negotiable, Diamond Grade (DG - Type XI) is the only choice. As the highest performing reflective sheeting on the market, Diamond Grade is specifically engineered for high-speed highways, complex intersections, and critical safety zones where every second of reaction time matters.
Using full-cube prismatic technology, Diamond Grade returns nearly double the light of High Intensity Prismatic (HIP), making it visible from extreme distances and wide angles.
Why Diamond Grade (Type XI) is the Global Safety Leader
In Canada, specifically for 400-series highways and high-speed rural routes, Diamond Grade is the gold standard. It provides the highest "conspicuity" (the ability to be noticed) in all lighting and weather conditions.
-
Technology: Full-Cube Prismatic (State-of-the-art efficiency).
-
Reflectivity: Ultra-high performance (approx. 500–600+ candelas).
-
Visibility Range: Effective up to 1,500+ feet.
-
Service Life: 12 years of outdoor durability.
-
Compliance: Exceeds ASTM D4956 Type XI and all MTO (Ministry of Transportation) highway requirements.
Primary Applications for Diamond Grade (Type XI) Signage
Because Diamond Grade (Type XI) is the highest performance level available, it is specifically reserved for environments where visibility is a direct factor in life-safety. In Canada, its use is standard for:
-
Highways & Interstates: Overhead guide signs and exit markers.
-
High-Speed Rural Roads: Sharp curve warnings and intersection alerts.
-
Critical Safety Areas: School zones and pedestrian crossings (often using Fluorescent Yellow-Green).
-
Complex Work Zones: Large construction markers for night-time visibility.
⚠️ Pro Tip: While Diamond Grade offers the highest performance for highways and high-risk zones, it may be more than what is required for private property or standard city streets. If you are looking for the best "value-for-money" material for municipal roads, explore our High Intensity Prismatic (HIP) Signs, which offer excellent durability at a mid-range price. For private parking lots, residential complexes, or indoor warehouse use, our Engineer Grade (EG) Signs provide the most affordable, high-quality reflective option to keep your project on budget.
