Economic Metal Road Stud for Road Safety Applications
Ceramic Road Studs for Road Safety Applications
Ceramic road stud for highway and road marking applications, offering high wear resistance and durable performance for traffic safety. Manufactured from premium kaolin-blend mineral formulations and fired at 1300°C into an ultra-dense, vitrified glazed ceramic body. These studs are designed for high-traffic municipal intersections, providing outstanding daytime color awareness, chemical immunity, and structural stability in regions with intense solar heat or dust storms.
Body Material: Kaolin mineral composite, 1300°C high-temperature integrated vitrified ceramic with a thick glazed finish.
Profile Geometry: Convex circular dome (95% industry standard) or optional square configurations.
Standard Sizing Matrix:
4-Inch (100mm): Diameter 100 mm, Height 20–35 mm, Net Weight 350 g.
6-Inch (150mm): Diameter 150 mm, Height 45–55 mm, Net Weight 1.4 kg.
8-Inch (200mm): Diameter 200 mm, Height 65 mm, Net Weight 2.8 kg.
Compressive Load Rating: Standard models ≥ 20 Tons; premium thick-sintered models up to 25 Tons.
Reflective Profiles: Pure Glazed Plain Style: No reflective element; relies entirely on daytime high-contrast visual signaling.
Single-Sided Reflective: Inset with a PMMA micro-bead reflective lens module.
Double-Sided Reflective: Symmetrical dual-lens installation.
Visibility Distance: ≥ 200 m on dry pavements.
Standard Glaze Finishes: High-saturation White and Highway Yellow; Red, Blue, and Green available for custom orders.
Bottom Structure: Patterned with an array of raised anti-slip bonding texture dots to maximize epoxy contact area and prevent dislodgement.
Installation Method: Pavement recessed or surface mounted via high-strength road-grade epoxy adhesives.
Unmatched Glaze Weatherability: The 1300°C fired porcelain glaze is completely UV-inert. It will not yellow, fade, or degrade over a 5-to-8 year outdoor cycle—outperforming plastics which yellow in 2 years, and aluminum which oxidizes and darkens in salty environments.
Hardness & Self-Cleaning Action: Rated at Mohs Hardness 6, the surface resists traffic abrasion. The smooth glaze sheds dust, sand, and oils under standard rainfall, making it perfect for arid, dust-prone regions.
Tactile Rumble Effect: The pronounced convex dome profile creates a distinct, audible haptic rumble when tires cross over it, alerting distracted drivers to correct lane drift.
Budget-Friendly for Large Municipal Projects: Lower raw material overhead yields a highly competitive unit price compared to cast aluminum or glass studs, making it ideal for large-scale municipal tenders in developing infrastructure markets.
Primary Layouts: Rural highways, gentle mountain curves, scenic corridor lane divisions, tunnel edges, toll booth lane guidance, traffic island boundaries, roundabouts, and municipal road works across the Middle East, Southeast Asia, and Africa.
Not Recommended For: Heavy-axle industrial shipping corridors (require ≥30T cast aluminum studs); premium high-speed wet-weather highways (require 360° glass cat-eyes); routes requiring intensive steel-blade snowplow deployment.
