60 kg/m Heavy Rail/ P60 Rail
Quick summary
60 kg/m (P60) heavy rail manufactured to GB/T 2585-2021 standards. Engineered to combine ride smoothness for high-speed service with durability for heavy freight. Suitable for welded high-speed tracks, heavy-haul mainlines and demanding industrial applications.
Product Highlights
Rail profile: 60 kg/m (P60) with optimized 60N head profile (7-segment arc) to reduce wheel–rail contact stress and grinding frequency.
Theoretical unit weight: 60.64 kg/m (production tolerance ±0.16 kg/m).
Manufacturing tolerances: Section ±0.5 mm; cut-length ±20 mm; hole position ±1 mm.
Bolt hole diameter: 31 mm (standard spacing 600 mm).
Operating temperature range: -40 °C to +60 °C (special steels available for extreme climates).
Key Points
High load capacity — Wide base (150 mm) and thick web (16.5 mm) disperse wheel loads effectively. Designed for axle loads ≥ 25 t (safe operating range 20–50 t).
Wear and fatigue resistance — Head quenching and tempering produce a hard, wear-resistant surface (330–380 HBW); alloying and heat treatment extend service life by 30%–50% (U75V can offer 2–3× life in heavy/high-speed service).
Precision manufacturing — Section tolerances within ±0.5 mm and straightness ≤ 0.3 mm/m for stable, smooth high-speed running.
Flexible lengths and processing — Standard 12.5 m / 25 m; customizable continuous rails up to 100 m for welded high-speed track. Accurately drilled bolt holes and saw-cut ends for easy installation.
Full quality assurance — Vacuum-degassed steelmaking, online heat treatment, 100% ultrasonic inspection, drop-weight impact testing and metallographic analysis; ISO 9001 certified.
Technical Specifications

Performance & Advantages
Outstanding load-bearing capacity — Wide foot and reinforced web reduce stress concentration and increase track stability under heavy axle loads.
Superior wear and fatigue resistance — Optimized alloy content and heat treatment reduce head wear and delay fatigue crack propagation.
High manufacturing accuracy — Tight dimensional control and straightness improve ride quality and reduce track maintenance.
Wide applicability — Designed for high-speed lines (≥200 km/h, up to 350 km/h), heavy-haul corridors, busy mainlines and industrial rail systems (ports, plants, warehouses).
