360 Degree Solar Road Stud for Highway Safety and Night Visibility
360 degree solar road stud with full directional LED illumination for highway safety and night driving visibility. This heavy-duty 360-degree solar road stud is built with a circular embedded die-cast aluminum frame. It features a wrap-around array of LEDs coupled with an autonomous solar charging core, combining active LED projection with wide-angle passive retroreflection. Engineered specifically for intelligent intersections, roundabouts, and multi-directional traffic zones, it ensures that oncoming drivers from any vector receive clear visual warnings.
Technical Specifications
Product Name: 360° Tempered Glass Cat Eye Road Stud.
Body Material: Monolithic high-silica optical toughened glass (seamlessly fused, no joints).
Reflective Structure: Vacuum-coated pure silver reflective layer at the base, delivering 360° omnidirectional spherical retroreflection.
Standard Dimensions: Base diameter 100 mm, overall height 50 mm; spherical dome protrusion height 19–25 mm, subterranean embedding depth 27 mm.
Net Weight: 520–550 g per unit.
Compressive Load Rating: Standard 20 Tons; Heavy-Duty reinforced version up to 40 Tons.
Visibility Distance: ≥ 500 m on dry surfaces; ≥ 200 m on flooded pavement (where standard aluminum reflective sheets suffer major attenuation).
Reflective Colors: White, Yellow, Red, Blue, Green (fully compliant with international road marking codes).
Operational Temperature Range: -45°C to +90°C. Resists acid rain, high coastal salt spray, and de-icing chemicals.
Self-Cleaning Properties: Completely smooth, non-porous spherical dome prevents silt, mud, and oil accumulation; automatically washes clean with natural rainfall.
Installation Method: Subsurface recessed embedding; core-drilled into the pavement and backfilled with epoxy or asphaltic structural grout.
Compliance Certifications: Certified to CE, EN1463, and ASTM retroreflective performance metrics for global export.
Core Advantages
Eliminates Intersectional Blind Spots: Standard square studs only project light forward and backward, leaving cross-traffic at roundabouts or T-junctions unguided. This wrap-around configuration provides clear visibility from any angle of approach.
Snowplow-Resilient Recessed Profile: By sinking the main chassis into the pavement, only the smooth dome remains exposed. This prevents damage or dislodgement from steel snowplow blades, while the heavy anchoring claws keep the unit firmly set in place under high-speed traffic.
60-Ton Industrial-Grade Rating: Thickened monoblock aluminum molding provides compressive strength that easily outclasses standard solar studs, making it suitable for ports, distribution yards, and heavy freight corridors.
Advanced Marine Corrosion Protection: The treated aluminum alloy resists oxidation from coastal salt spray, winter melting salts, and spilled engine fluids.
Applications
Primary Layouts: High-speed highway interchanges, traffic roundabouts, crossroads, toll lanes, smart crosswalk borders, pedestrian safety zones, heavy port transit corridors, container berths, winding mountain junctions, cliffside routes, steep descent zones, and municipal routes prone to heavy snow and ice clearance operations.
Not Recommended For: Extended straight highway lane delineation (square bidirectional solar studs are more cost-effective); short-term construction zone diversions; low-budget rural pathways.
