A steel rail is a precision-rolled steel profile that establishes the running surface and structural continuity of a track, ensuring vehicles remain aligned while resisting bending, shear, and surface wear. Its geometry and metallurgy are selected to balance strength and durability under repetitive loading.
GNEE RAIL offers rails manufactured to GB, UIC, DIN536, JIS, AS1085, BS11, and AREMA/ASCE standards, including light rail, heavy rail, and crane rail series such as QU and DIN A-profiles, together with services for length customization, welding preparation, and accessory matching.
What are the dimensions of ASCE 25 rail?
The ASCE 25 features a symmetrical 'I-beam' (tee) profile, designed for light-duty rail applications. Its dimensions are as follows: head width of 38.1 mm, height of 69.85 mm, base width of 69.85 mm, and web thickness of 7.54 mm. The theoretical weight is approximately 12.4 kg per meter. This lightweight design facilitates easier transportation and installation, making it particularly suitable for medium-span bridges and temporary track setups.
ASCE 25 rails are the lightest rail type in ASCE rails, weighing 25 pounds per yard(25lb/yd). They are primarily used in low-speed applications such as light rail transit systems and industrial tracks.

- Easy Installation & Maintenance:Lightweight design reduces installation labor and equipment costs, while robust materials minimize long-term maintenance needs.
What is the difference between ASCE 25 rail and GB 22kg rail?
The main difference is their weight, standard, and typical application: ASCE 25 (25 lb/yd, approx. 12.4 kg/m) is a lighter American standard rail used for very light-duty needs, while GB 22kg rail (22 kg/m) is a Chinese standard light rail for slightly heavier, but still light-duty industrial, mining, and temporary uses, both providing stable paths but with differing load capacities.
ASCE 25 Rail (25 lb/yd)
- Standard: American Society of Civil Engineers (ASCE) standard, often used in North America.
- Weight: Approximately 25 pounds per yard, or about 12.4 kilograms per meter.
- Profile: A specific tee-shaped profile (head, web, base).
- Application: Very light-duty, such as for temporary construction, mining, or internal factory transport where loads are minimal.
GB 22kg Rail (22 kg/m)
- Standard: Chinese National Standard (GB/T 11264).
- Weight: Approximately 22 kilograms per meter.
- Profile: A standard light rail profile, often made from carbon steel.
- Application: Light-duty applications like mining railways, factory tracks, temporary construction lines, and light crane tracks where moderate loads are present.
