Diamond Grade Type IV Reflective Sheeting
Red & White High-Performance Prismatic Film for Critical Road Safety Applications
In modern traffic management, visibility is not optional - it is essential.
Diamond Grade Type IV Reflective Sheeting is engineered to deliver superior retroreflectivity, long-distance visibility, and long-term outdoor durability.
At DINGFEI Reflective Material, we supply high-quality Diamond Grade Type IV reflective sheeting in Red and White, widely used in regulatory, warning, and safety marking systems worldwide.
What is Diamond Grade Type IV Reflective Sheeting?
Diamond Grade Type IV is a high-intensity microprismatic reflective film designed for permanent traffic signs and critical safety applications.
Compared with engineering-grade reflective film, Type IV provides:
- Higher brightness
- Longer detection distance
- Wider entrance and observation angles
- Stronger weather resistance
- Longer outdoor service life
It ensures that road signs remain visible at night, in rain, and under low-light conditions.
White Diamond Grade Reflective Sheeting
The Foundation of Regulatory and Guide Signs
Main Applications of White Diamond Grade Sheeting:
White reflective film is the base color for most traffic signs. It provides maximum light return and high contrast when printed or overlaid.
It is commonly used for:
- Highway guide signs
- Directional signs
- Speed limit signs
- Informational road signs
- Construction temporary signs
- Parking and facility signs
White diamond grade sheeting ensures excellent clarity when combined with black, green, blue, or red overlays.
Why White is Critical
White offers:
- Highest overall reflectivity
- Clean background contrast
- Long-distance readability
- Stable color performance under UV exposure
For high-speed highways and urban traffic systems, white diamond grade film is the most commonly specified material for permanent signage.
Red Diamond Grade Reflective Sheeting
High-Impact Visibility for Warning & Prohibition Signs
Main Applications of Red Diamond Grade Sheeting:
Red is internationally recognized as a color of prohibition and danger. It must deliver strong brightness and stable chromaticity.
Red diamond grade sheeting is widely used for:
- STOP signs
- No Entry signs
- Yield signs
- Prohibition signs
- Hazard warning borders
- Emergency signage
Why Red Requires High Performance
Red pigments naturally reflect less light than white.
Therefore, a high-grade prismatic structure is essential to:
- Maintain strong nighttime brightness
- Meet international traffic standards
- Ensure consistent color under headlight illumination
- Provide long-distance detection
Diamond Grade Type IV ensures red signs remain highly visible even in complex lighting environments.
