Aluminium Road Stud — Die-Cast Body with Ceramic Retroreflector
Roadsidesafe aluminium road studs provide permanent, maintenance-free retroreflective lane marking for highways, airports, tunnels, bridge decks, and urban road networks across Europe, North America, Australia/NZ, Southeast Asia, and the Middle East. The die-cast aluminium body offers superior load resistance compared to plastic, while the ceramic prismatic retroreflector delivers consistent retroreflection without power or maintenance for 7–10 years.
Why Aluminium Over Plastic?
| Feature | Aluminium | Plastic |
|---|---|---|
| Load resistance | Up to 20 tons (cast iron equiv.) | Up to 5 tons |
| Body durability | Will not crack or shatter | Can crack under heavy loads |
| Best for | Highways, freight routes, airports | Low-speed urban roads |
| Snowplough resistance | Flush mount — no protrusion | May dislodge if raised |
| Retroreflector | Ceramic prismatic | Glass bead or prismatic |
Key Features
- Die-Cast Aluminium Body: Impact-resistant — withstands snowplough blades, heavy freight tyres, and daily highway traffic without cracking.
- Ceramic Prismatic Retroreflector: Retroreflection ≥ 300 mcd/lx/m² (EN1463-1 Class C2) — maintains performance in rain, mud, and fog.
- Flush or Raised Mount: Flush profile for snowplough routes; raised for standard road marking visibility.
- Epoxy or Bolt Fixing: Epoxy for asphalt; bolt-down for concrete, bridge decks, and airport taxiways.
- Colour-Coded: White (lane dividers), Yellow (centreline), Red (wrong-way), Blue (fire hydrant marker).

FAQ
Q: Can aluminium road studs be used on airport taxiways?
A: Yes. Flush-mount aluminium studs with epoxy fixing are FAA and ICAO-compatible for taxiway edge and centreline marking. Specify flush-mount in your order.
Q: What retroreflector colours are available for wrong-way marking?
A: Red retroreflectors (visible only from the wrong direction) are available for highway wrong-way driver detection marking — a requirement in many European jurisdictions.
