What is Light steel rail?
Light steel rail refers to lighter-weight steel tracks, typically weighing 30 kg per meter or less, used for temporary, low-load, or specialized transport in places like mines, construction sites, factories, and forestry, offering benefits like lower cost, easier handling, and quick installation compared to heavy rail. Common types are designated by their weight (e.g., P8, P12, P18, P24) and made from durable materials like Q235 or 55Q steel.
GB 22kg rail vs JIS 22kg steel rail
GB 22kg rail and JIS 22kg rail are often dimensionally identical and interchangeable for light industrial or mining use, complying with China's GB/T 11264 and Japan's JIS E 1101 standards, respectively, but always verify specific dimensions and material grades for critical applications, as bolt hole spacing might differ slightly, requiring specific fishplates, though material standards (like Q235B, U50Mn) can be similar for matching performance.
Key Similarities
- Dimensional Match: The cross-sectional profiles (head, web, base dimensions) for 22kg/m rails under GB and JIS standards are often identical, making them interchangeable in many cases.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Light Rail | 8 KG/M | 65 | 25 | 54 | 7 | 8.42 |
| 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 | |
| 30 KG/M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
JIS 22kg steel rail

Key Differences & Considerations
- Standards: GB refers to Chinese National Standards (GB/T 11264), while JIS refers to Japanese Industrial Standards (JIS E 1101).
- Accessories: While the rails themselves match, fishplates (rail joints) and bolts might have different hole patterns (e.g., bolt hole spacing), requiring specific matching accessories for each standard, say some sources.
- Material Grades: Both standards offer various steel grades (e.g., Q235B, 55Q, manganese steels like U50Mn) with different strengths and wear resistance, so ensure material properties align for performance.
