What Is GB Standard 24KG Light Steel Rail?
Light steel rail refers to a category of railway rail products with relatively low unit weight per meter, typically ranging from 8kg/m to 30kg/m. These rails are designed for light-load transportation systems rather than heavy-duty mainline railways. Among them, the GB Standard 24KG Light Steel Rail is one of the most widely used specifications in industrial railways, mining rail systems, and temporary track installations.
A 24kg rail means the rail weighs 24 kilograms per meter, which provides an ideal balance between structural strength and installation flexibility. Compared with heavier rails, 24kg light steel rails are easier to transport, faster to install, and more cost-efficient, especially for short-distance or internal transportation systems.
Key Dimensions of GB 24KG Light Steel Rail
| Parameter | Value |
|---|---|
| Weight | 24 kg/m |
| Rail Height | 107 mm |
| Head Width | 51 mm |
| Web Thickness | 10 mm |
| Base Width | 92 mm |
| Standard Length | 6m / 9m / 12m (customizable) |
These dimensions follow Chinese GB railway standards, ensuring consistent mechanical performance and compatibility with matching fasteners and sleepers.
Chemical Composition (Typical)
| Element | Content (%) |
|---|---|
| Carbon (C) | 0.50 – 0.60 |
| Manganese (Mn) | 0.60 – 0.90 |
| Silicon (Si) | ≤0.40 |
| Phosphorus (P) | ≤0.040 |
| Sulfur (S) | ≤0.040 |
This composition provides sufficient hardness and wear resistance while maintaining good weldability, which is critical for rail joints and on-site modifications.
Typical Applications of 24KG Light Steel Rail
The GB 24kg rail is commonly used in:
Mining rail systems
Industrial plant railways
Brick factories and cement plants
Harbor internal transportation
Temporary construction rail tracks
Compared with heavier rails like 38kg or 50kg, the 24kg rail is more economical for low-speed, light-load environments.
Comparison with Other Light Rails
| Rail Type | Weight (kg/m) | Typical Application |
|---|---|---|
| 15kg Rail | 15 | Light carts, temporary tracks |
| 24kg Rail | 24 | Industrial & mining transport |
| 30kg Rail | 30 | Medium-load industrial railways |
The 24kg rail stands out as the most versatile choice in light rail categories.
