Safer Road / Manhole cover

Safer Road
Safer Road

This is a manhole cover that can indicate the road safety problems. Since the color of the manhole cover and support is similar to the road, when the manhole cover is lost or misplaced, drivers can’t accurately observe it. So, the angle of the contact surface between the manhole cover and the support is expanded. Applying red fluorescent paint on the outer wall of the manhole cover and the inner wall of the support. The paint is red during the day and easy to recognize, showing fluorescence at night to ensure driving safety. This design can warn people timely, reducing the human inspection. No need to place safety cones successively either.
