Steel Rails are the key parts of the rail track laid in two parallel lines to provide a continuous, steady and level surface for the runnings of trains. Heavier train and fast speed requires higher requirements to withstand stresses, so they are produced from high carbon steel (carbon -0.6 % to 0.8 %, manganese 0.8%-1.3 %, silicon 0.1 % -0.5 %, sulphur and phosphorus0.03 % maximum each, and aluminum 0.015 % maximum).
What is the height of a 60 kg rail?
A 60 kg rail weighs around 60 kg per meter (e.g., 60.6 kg/m) and typically comes in standard lengths of 12 to 25 meters (approx. 39 to 82 feet), though custom lengths are often available for specific project needs, designed for heavy-haul and high-speed railways.
Key Specifications (GB Standard Example)
- Weight: ~60.6 kg/m
- Rail Height: 176 mm (approx. 6.9 inches)
- Head Width: 73 mm (approx. 2.9 inches)
- Bottom Width (Base): 150 mm (approx. 5.9 inches)
- Web Thickness: 16.5 mm (approx. 0.65 inches)
Common Lengths
- Standard lengths often cited: 12m, 12.5m, 18m, 25m.
- Can be produced to meet specific project requirements.
Usage
- A heavy-haul rail section used in main line railways.
- Suitable for high-speed rail (up to 160 km/h) and high traffic density (around 60 GMT).
Chinese Standard GB 60KG Rail
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.

JIS 60kg Rail
The JIS 60kg rail, weighing 60.8kg per meter, is one of the most robust models in the JIS range. Built to JIS E 1101-2001 standards and manufactured from U71Mn steel, it delivers superior strength, fatigue resistance, and long-term performance. Suitable for high-speed rail lines, busy freight corridors, and mainline infrastructure, this rail ensures long-term safety and durability in demanding transit networks.
Rail Specification
| Height: 174mm | Base Width: 145mm |
| Head Width: 65mm | Web Thickness: 16.5 mm |
| Length: 6m-24m | Material: U71Mn |
| Weight: 60.8kg/m | Standard: JIS E 1101-2001 |
Chinese Standard GB 60KG Rail vs JIS 60kg Rail
Chinese GB 60kg rail (GB2585-2007) and Japanese JIS 60kg rail (JIS E1101) are both heavy-duty 60 kg/m rails, often using similar high-carbon steel (U71Mn), but differ slightly in profile dimensions (height, width, thickness) and specific material grades (e.g., GB uses U71MnG/U75V, JIS uses U71Mn), with GB rails optimized for China's high-speed lines and JIS for Japanese industrial needs, though they can be cross-compatible in some applications.
Dimensions (Approximate):
JIS 60kg: Height ~174mm, Head Width ~65mm, Web Thickness ~16.5mm, Bottom Width ~145mm.
GB 60kg: Similar heavy-haul profile, often with slight variations in dimensions, focusing on high strength and fatigue resistance.
Application:
GB 60kg is for China's high-speed & heavy-haul lines; JIS 60kg is for heavy industry and main lines in Japan, known for excellent mechanical properties.
Compatibility: JIS 60kg rails are noted as being compatible with Chinese GB 2585 standards, allowing for some interchangeability.
