Heavy steel rail is widely used in modern railway infrastructure where high axle loads, long service life, and stable operation are required. These heavy-duty rails are commonly used in China’s domestic and international railway projects, including high-speed railways, heavy-haul freight lines, and demanding industrial tracks.
Glory Steel Work supplies heavy steel rails with standard profiles from 38kg to 75kg, manufactured in accordance with GB 2585-2007. Our rails are produced using proven steel grades such as U71Mn and U75V, providing reliable strength, wear resistance, and consistent performance under heavy-duty service conditions.

The performance of heavy steel rails is significantly influenced by the quality of the material. Glory Steel Work offers rails made of the well-known U71Mn and U75V steel grades in railway engineering. We can also offer custom steel grades to satisfy particular project requirements for clients with particular needs.
🔹 U71Mn
Excellent toughness, wear resistance, and cost-effective performance for long-term operation make it suitable for heavy-haul freight routes and ordinary railway lines.
🔹 U75V
Designed for high-speed and high-stress railway systems, with enhanced strength and fatigue resistance, making it ideal for applications that demand superior dimensional stability and extended service life.
High-Speed Railways：60kg and 75kg heavy steel rails made with U75V steel deliver stable performance, long service life, and reliable safety for high-speed passenger lines.
Heavy-Haul Freight Lines：50kg and 60kg rails in U71Mn steel provide high load capacity and strong wear resistance for continuous heavy-haul freight transport.
Urban & Regional Transit：38kg and 43kg rails are commonly used in metro and regional rail systems, where consistent performance and standardized profiles are required.
Industrial Tracks：Heavy railway rails are widely applied in ports, steel plants, mining areas, and logistics yards, offering durability under high loads and harsh conditions.
