Here is a standard specification for an Aluminium Road Stud, commonly used in road safety infrastructure for lane marking, night visibility, and traffic guidance.
✅ SPECIFICATION OF ALUMINIUM ROAD STUD
1. Product Description:
Aluminium road studs are retro-reflective markers used on roads to guide drivers by providing enhanced visibility, especially at night or in poor weather. Made from cast aluminium, they are known for their durability, load-bearing capacity, and weather resistance.
2. Application Areas:
-
Centerline and edge line markings on highways
-
Sharp curves, bridges, and flyovers
-
Toll plazas, pedestrian crossings, and intersections
-
Parking lots and private roads
