Heavy Rail
Heavy rail refers to steel rails >30kg/m, primarily employed in heavy-haul locomotives, power plants, railway/transportation infrastructure, subways, and urban rail networks.
Key Features of Heavy Rails
- Weight Range:38kg/m to 75kg/m（38kg,43kg,50kg,60kg,75kg）, engineered for extreme load-bearing requirements.
- Steel Grade:U71Mn – High-strength manganese steel with superior durability and fatigue resistance.
- Compliance: Meets GB2585-2007 standards for safety and performance.
Rail Specifications (GB2585-2007)

Applications of Heavy Rail
Heavy rail is widely used across transportation and industrial sectors, offering the strength and reliability required for high-load, high-frequency operations.
✅Railway Infrastructure
Used in mainline tracks, turnouts, and rail crossings, heavy rail supports long-distance travel, high-speed operation, and heavy axle load requirements.
✅Urban Transit Systems
Ideal for subways, trams, and light rail networks, it ensures smooth, low-noise performance and durability in high-traffic urban transportation systems.
✅Industrial Zones & Logistics
Deployed in ports, steel mills, and mining corridors, heavy rail handles continuous stress from freight trains and heavy machinery over long operation cycles.
How to Select the Right Heavy Rail
- Determine Load Requirements: Match rail weight (e.g., 60kg/m for mainlines) to operational demands.
- Environmental Factors: Opt for U71Mn steel in corrosive or high-impact environments.
- Compliance: Ensure adherence to GB2585-2007 for safety certifications.
- Determine Load Requirements: Match rail weight (e.g., 60kg/m for mainlines) to operational demands.
Installation & Maintenance Best Practices
- Use precision alignment tools to prevent track misalignment.
- Conduct ultrasonic testing annually to detect internal flaws.
- Apply anti-corrosion coatings in coastal or humid regions.
