Grooved Rail
Product Overview
Grooved Rails, specialized steel rails with a preformed guiding groove in the railhead, ensure anti-derailment through precise engagement between wheel flanges and the groove. They enable seamless integration with road surfaces, serving as a core component for modern trams and low-capacity rail transit systems.
Core Advantages
- Unmatched Safety Performance
Anti-Derailment Design: Wheel flanges fit into the groove, limiting lateral deviation to ≤±2mm on 25m small-radius curves – a 50% safety improvement over traditional rails.
International Standard Compliance: Meets EN 14811 and China’s Technical Specifications for Urban Rail Transit Grooved Rails, with railhead precision up to ±0.3mm. - Optimal Urban Integration
Flush Surface Design: Rails align seamlessly with roads, allowing safe passage for vehicles and pedestrians while increasing lane utilization by 40%.
Multi-Scenario Adaptability: Suitable for complex urban environments, including exclusive right-of-way sections, shared road intersections, embedded tracks, and grassed areas. - Globally Leading Technology
Domestic Technological Breakthrough: Chinese enterprises master core rolling technologies; 59R2/60R2 models outperform global first-class standards.
End-to-End Capabilities: Covers high-precision rolling (dimension fluctuation <0.15mm), flash butt welding (joint strength up to 98% of parent material), and intelligent monitoring.

FAQs
Q: What urban scenarios are suitable for grooved rails?
Ideal for complex environments requiring shared road-rail space, such as city center roads, scenic areas, and urban renewal projects, supporting flexible switching between exclusive and open right-of-way.
Q: What is a grooved rail, and how does it differ from standard rails?
A: A grooved rail (also called a “channel rail”) features a recessed groove along its top surface, designed specifically for guided movement of wheels (e.g., crane wheels, railcar wheels) with matching flanges. Unlike standard flat-bottom rails, the groove ensures precise lateral alignment, prevents derailment, and reduces friction—making it ideal for applications requiring controlled, repetitive movement.
Q: Can you provide custom grooved rail solutions (e.g., non-standard lengths)?
- Lengths (e.g., cut-to-size for specific project layouts)
- Groove dimensions (tailored to unique wheel profiles)
- Surface treatments (e.g., heat treatment, galvanization, painting).
