GB 60kg rail is a heavy-haul railway track material conforming to China's national standard GB2585-2007, with a unit weight of 60.64kg/m. It is made of high-carbon manganese steel (50Mn/U71Mn), featuring both high strength and anti-fatigue properties. It is specially designed for scenarios subject to dynamic load impact of locomotives and high-frequency rolling, and is applicable to national railway trunk lines, subways and industrial transportation lines.

Key Features and Advantages of GB 60kg Rail
- Structurally, the 60kg rail features a large head and base (head width 75mm, base width 150mm, height 176mm), effectively distributing wheel pressure and minimizing stress concentration on sleepers and base plates, thereby extending the service life of the entire track system.
- The U71Mn steel used in GB 60kg rail is a medium-to-high carbon manganese steel, known for its hardness and superior wear resistance. After heat treatment, the head surface hardness reaches 260–300 HBW, making it suitable for high-speed and heavy-load train operations.
| Steel Grade | C(%) | Si | Mn | Cr | V | P | S | Tensile Strength (Rm/MPa) |
| U71Mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | ≤0.035 | ≤0.030 | ≥880 |
- GB 60kg rail has excellent weldability and compatibility with various railway fastening systems.
In addition to the GB 60kg rail, GNEE RAIL also supplies various heavy and crane rail types such as P43, P50, U71Mn QU80, and U75V QU100, along with matching rail clips, bolts, base plates, rubber pads, and technical installation support services.
