Product Overview
The REFLECT-IT SG Road Stud is an advanced 360-degree reflective guidance system designed for complex road geometries where vehicle approach angles frequently change. Unlike traditional uni-directional markers, the SG model reflects light from all angles, making it the premier choice for enhancing safety on curved roads, winding mountain routes, and intricate junction layouts.
Constructed from high-performance tempered optical glass, the SG Road Stud provides a level of durability and consistent retro-reflectivity that plastic alternatives cannot match. It is engineered to withstand the most demanding environmental conditions and heavy traffic volumes whilst remaining slip-proof for all road users. This "all-round" visibility ensures that drivers receive continuous visual cues regardless of their line of sight or the road's curvature.
With a service life exceeding ten years and a robust resistance to physical impact and chemical degradation, the SG Road Stud offers infrastructure managers a low-maintenance, high-impact solution for modern transport networks. It represents a vital component in reducing accidents in areas where standard delineation may be insufficient.
Key Benefits
- 360-Degree Coverage: Provides omni-directional reflectivity, ensuring reliable visibility for drivers approaching from any angle or navigating tight bends.
- Exceptional Load Bearing: Engineered to withstand compressive forces of over 60 tonnes (588 kN), making it suitable for the heaviest transit routes.
- Slip-Proof Design: The tempered glass body is designed with safety in mind, providing a slip-resistant surface for vehicles and cyclists.
- Maintainable Performance: The solid glass construction resists the scratching and dulling that affects plastic studs, maintaining high-intensity reflection for over 10 years.
- Versatile Geometry: Specifically developed to reinforce guidance in areas with complex geometry where traditional markers fall short.
Applications
The SG Road Stud excels in environments requiring multi-angle visual reinforcement:
- Curved Roads & Bends: Providing continuous guidance through turns where headlights hit markers at varying angles.
- Complex Junctions & Roundabouts: Assisting drivers in navigating changing lanes and exit points with 360-degree feedback.
- Mountain & Winding Routes: Enhancing safety on roads with frequent changes in elevation and direction.
- Junction Aprons: Marking boundaries in areas where vehicles may approach from multiple side-roads.

The REFLECT-IT Advantage
Universal Guidance for Safer Infrastructure
The SG Road Stud is a testament to the engineering philosophy of the REFLECT-IT range, providing superior optical performance where legacy systems fail. By offering 360-degree reflection, it eliminates "dark spots" on the road network:
- Adaptive Visibility: Light is returned to the driver regardless of the vehicle's approach angle, providing a constant stream of information.
- Enhanced Geometry Perception: Drivers can better perceive the true shape of a curve or junction well in advance, allowing for safer speed adjustments.
- Reduced Maintenance Burdens: The high load rating and tempered glass finish ensure the studs remain functional and bright long after plastic versions have failed.
Sustainability & Environmental Considerations
Sustainability is built into the long-term performance of the SG series:
- Resource Efficiency: The 10+ year service life means significantly fewer units are manufactured, transported, and installed over the life of the road.
- Low Impact Materials: Tempered glass is a durable, non-toxic material that does not shed microplastics into the surrounding environment.
- Operational Safety: Reliable delineation reduces the likelihood of accidents, which in turn reduces the environmental and economic costs of road incidents.
Installation & Maintenance
Designed for professional installation and minimal lifelong intervention:
- Installation: Recommended fixing using high-strength, styrene-free injection resins into a prepared 102mm cavity.
- Self-Cleaning Action: The rounded glass dome is designed to shed water and road debris through natural rainfall and passing traffic turbulence.
- Durability: Designed to survive repeated heavy vehicle crossovers without loss of structural or optical integrity.
