What is GB Standard 24kg rail?
In simple terms, a GB Standard 24kg rail is a type of light steel rail, manufactured according to the Chinese national railway standard GB/T 11264-2012, and it typically weighs 24.46 kilograms per meter. This balanced weight category places it between ultra-light rails (such as 15kg or 18kg rails) and heavier industrial rails (such as 30kg), offering a perfect blend of strength, ease of installation, and cost-performance for many applications.
Key Technical Specifications of 24KG Rail
Below is a concise overview of the GB Standard 24kg rail basic dimensions and typical grade:
| Parameter | Value |
|---|---|
| Standard | GB/T 11264-2012 |
| Weight | 24.46 kg/m |
| Rail Height | 107 mm |
| Base Width | 92 mm |
| Head Width | 51 mm |
| Web Thickness | 10.9 mm |
| Typical Material Grades | Q235B or 55Q |
| Standard Lengths | 6m, 8m, 10m, 12m, or custom |
Note: Individual projects may specify specific tolerances, hole locations, or weld zones, and these customizations can be provided by a reliable rail manufacturer.
Why This Rail Profile Matters
The I-shaped cross section provides excellent bending resistance and distributes wheel loads efficiently, ensuring stable and long-lasting rails under moderate loads. Such design fundamentals explain why 24kg rails are a widely accepted solution in various track systems.
Typical Applications of GB Standard 24KG Rail
The versatility of GB Standard 24kg rail makes it suitable for many practical settings, including:
Mining Transportation Systems: Ideal for underground mine tracks, ore cart lines, and hopper feed spurs.
Industrial & Factory Tracks: Used in workshops, logistics yards, and material-handling corridors.
Light Crane Runways: Suitable for light overhead cranes and gantry cranes.
Temporary Construction Line: For tunnelling work, site transport, and short-term installations.
Port & Yard Lines: Used in port shunting and material transfer zones.
Tourist or Recreational Rails: Mini-rail or park transport lines with light loads.
Materials and Mechanical Characteristics
Typically made from Q235B (good weldability and ductility) or 55Q (higher strength and wear resistance), 24kg rails are robust enough for repeated loading cycles while offering cost-competitive performance.
Understanding what GB Standard 24kg rail is and why it's widely used helps buyers and engineers choose the right rail solution for their project environment, whether it's a mine, factory, or temporary track. With a balanced weight and reliable material properties, this rail type continues to be a trusted choice in light to medium duty rail systems.
