What is the Main Application of GB/T Standard 22KG Mining Rail?
Jan 19, 2026
The China 22KG Light Rail Railway Track refers to a specific type of steel rail designed according to Chinese standards, weighing 22 kilograms per meter. It belongs to the category of light rails, which are generally used for low-speed, light-load railway systems such as mining tracks, industrial railways, agricultural rail lines, and light-duty transport systems.GNEE RAIL offers China Standard 22 kg/m (P22) light steel rail built to GB11264-2012 or GB11264-89 standards.

| 9 KG/M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |
| 12 KG/M | 69.85 | 38.1 | 69.85 | 7.54 | 12.2 | |
| 15 KG/M | 79.37 | 42.86 | 79.37 | 8.33 | 15.2 | |
| 18 KG/M | 80 | 40 | 80 | 10 | 18.06 | |
| 22 KG/M | 93.66 | 50.8 | 93.66 | 10.72 | 22.3 | |
| 24 KG/M | 107 | 51 | 90 | 10.9 | 24.46 | |

What is the Main Application of GB/T Standard 22KG Mining Rail?
A steel rail used in industrial and mining transport is a hot-rolled carbon steel profile designed to guide small rolling stock and safely transmit wheel loads to sleepers and the supporting ground structure. Compared with heavy mainline railway rails, light rails focus more on installation flexibility, cost efficiency, and adaptability to narrow spaces. GB/T Standard 22KG mining rail is one of the most widely used light rail sections in mining and industrial logistics systems, offering a practical balance between load capacity and ease of handling.
Why Is GB/T 22KG Rail Widely Used in Underground Mining Transport?
The primary application of GB/T 22kg mining rail is underground mine haulage systems, where mine cars or small battery locomotives transport coal, ore, and materials between working faces and shafts. In these environments, track layouts are frequently adjusted as mining advances, so rails must be easy to transport, cut, and reinstall.
GB/T 22kg rail has a nominal weight of about 22.3 kg per meter, which allows manual handling in confined tunnels while still providing sufficient bending strength for typical mine car axle loads. Its relatively compact section height also reduces the excavation size required for track installation, helping control tunneling costs.
Typical Underground Applications
| Application Area | Operational Characteristics | Why 22kg Rail Is Suitable |
|---|---|---|
| Coal mine galleries | Narrow tunnels, frequent relocation | Lightweight, easy installation |
| Metal ore mines | Medium wheel loads, tight curves | Adequate strength and flexibility |
| Auxiliary tunnels | Temporary or semi-permanent tracks | Low cost, reusable rails |
In such systems, GNEE RAIL not only supplies the rail itself but also provides matching fishplates and bolts designed for frequent assembly and disassembly, helping mines reduce downtime during track relocation.
Is GB/T 22KG Rail Suitable for Temporary and Portable Track Systems?
Another important application of GB/T 22kg mining rail is in temporary and portable rail track systems, commonly used in construction sites, tunnel projects, and short-term material transport operations. These tracks are frequently dismantled and reused, so durability, straightness retention, and joint reliability are critical.
Compared with lighter sections such as 12kg or 15kg rails, 22kg rail provides better resistance to bending and joint loosening when tracks are repeatedly assembled and dismantled. At the same time, it remains significantly easier to handle than heavy rails such as 38kg or 50kg sections.
Comparison of Light Rails for Temporary Tracks
| Rail Type | Weight (kg/m) | Structural Stability | Reusability |
|---|---|---|---|
| 15kg rail | ≈15.2 | Moderate | Good |
| 22kg rail | ≈22.3 | High | Very good |
| 30kg rail | ≈30.1 | Very high | Lower handling efficiency |
For contractors who frequently relocate track lines, GNEE RAIL can provide pre-drilled rail ends, customized joint bars, and modular fastening sets to improve installation efficiency and extend rail service life.
