TR57 Rail
Product Overview
115RE (TR57) rail Designed specifically for high-intensity railway networks, it has become the core choice for heavy-haul freight and industrial rails with its excellent load-bearing capacity and ultra-long durability. Compliant with the American AREMA standards, it is suitable for harsh scenarios with an axle load of ≥25t. It is widely used in heavy-haul main lines, industrial plants, and hub stations, and is a rail solution that balances “heavy-haul performance + long-term stability”.
Performance Highlights
🔹 Superior Wear Resistance: With a rail head hardness of 280-320 HB, it resists wear from heavy-duty freight wheel sets, extending the service life by 20-25% compared to standard grades and is suitable for high-frequency freight lines.
🔹 Enhanced Corrosion Resistance: Optional hot-dip galvanizing/epoxy coating is available for corrosive environments such as humid areas, coastal regions, and mining zones, prolonging the service life of port/mining rails.
🔹 Heavy-Load Adaptability: Supports an axle load of ≥25t, meeting the long-term stable operation requirements for heavy-load transportation of coal, ore, containers, etc.
