Light steel rails
Light steel rails are an essential component of many industrial and mining transportation systems. Unlike heavy-duty mainline railway rails, light steel rails are designed for lower axle loads, controlled speeds, and shorter transportation distances, where flexibility, cost efficiency, and ease of installation are critical. Among these products, GB Standard 24KG Light Steel Rail has become one of the most widely adopted specifications across global industrial projects.
The term "24kg rail" refers to the nominal weight of the rail per meter, which is approximately 24 kilograms. This weight category places the rail in the middle range of light steel rails, offering a balance between mechanical strength and practical handling. Manufactured in accordance with Chinese GB railway standards, the 24kg light steel rail ensures consistent dimensions, stable mechanical performance, and compatibility with a wide range of rail fasteners and sleepers.
Basic Dimensions of GB Standard 24KG Light Steel Rail
| Parameter | Specification |
|---|---|
| Standard | GB/T 11264 |
| Weight | 24 kg/m |
| Rail Height | 107 mm |
| Head Width | 51 mm |
| Base Width | 92 mm |
| Web Thickness | 10–11 mm |
| Standard Lengths | 6 m, 9 m, 12 m (custom available) |
These standardized dimensions are crucial for ensuring smooth wheel-rail contact, minimizing vibration, and maintaining long-term track stability in industrial environments.
Typical Material and Chemical Composition
| Element | Typical 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 |
The carefully controlled chemical composition gives the 24kg light steel rail adequate hardness for wear resistance while maintaining good toughness and weldability, which is especially important for industrial rail tracks that may require on-site cutting or welding.
Why 24KG Light Steel Rail Is Widely Used
In industrial and mining rail systems, rails are subjected to repetitive loading rather than extreme axle loads or high speeds. The GB standard 24kg rail is engineered to meet exactly these conditions. Compared with lighter rails, it offers better resistance to deformation and longer service life. Compared with heavier rails, it significantly reduces material cost, installation difficulty, and foundation requirements.
Because of this balance, GB Standard 24KG Light Steel Rail is widely used in mining transport, factory internal railways, construction site logistics, ports, warehouses, and temporary rail tracks.
As an experienced railway material manufacturer and exporter, GNEE STEEL supplies GB standard 24kg light steel rails with strict quality control and complete technical documentation. In addition to rails, GNEE STEEL provides a full range of rail fasteners, fishplates, bolts, clips, and sleepers, allowing customers to source complete rail systems from one reliable supplier.
