What are the specifications of GB/T Standard 22KG Mining Rail?
Jan 19, 2026
The 22kg light steel rail is a high-performance solution designed for medium-to-heavy-duty industrial and mining applications. Compliant with GB/T 11264-2012 standards, it is available in two premium materials: Q235 low-carbon steel for general durability and 55Q high-carbon steel for extreme wear resistance. With a weight of 22.3kg/m and robust dimensions (93.66mm height/base), this rail excels in mining haulage, railway sidings, and heavy equipment transport, offering superior load-bearing capacity and long-term reliability.
What are the specifications of GB/T Standard 22KG Mining Rail?
Under the Chinese light rail standard GB/T 11264 (formerly GB11264-89), the 22kg rail refers to the nominal mass of approximately 22.3 kg per meter, and the section geometry is optimized to balance bending strength and ease of installation in narrow mining tunnels and industrial yards.
| 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 | |
This geometry provides sufficient vertical stiffness for mine haulage while keeping the rail light enough for manual handling during installation. The symmetrical head and base also allow easier alignment on timber sleepers, steel sleepers, or concrete slabs, which is common in mining transport systems.
Compared with heavier railway rails such as UIC54 (54.43 kg/m) or AREMA 115RE (56.9 kg/m) used on freight and passenger lines, GB/T 22kg rail is designed for lower axle loads but higher operational flexibility, which is essential in mines where track layout changes frequently with production progress.

How Does GB/T 22KG Rail Compare with Other International Light Rail Standards?
Mining and industrial rail projects often involve equipment sourced from different countries, making cross-standard comparison important. GB/T 22kg rail is functionally similar to several international light rail sections used in industrial transport systems.
Comparison of Typical Light Rail Standards
| Standard | Rail Type | Weight (kg/m) | Height (mm) | Typical Applications |
|---|---|---|---|---|
| GB/T | 22kg | 22.3 | 93.66 | Mining haulage, factories, ports |
| JIS | 22kg | 22.3 | 93.66 | Industrial tracks, depots |
| DIN | A55 | 31.8 | 65 | Crane and light transport systems |
| ASTM/ASCE | ASCE30 | 14.9 | 79.4 | Temporary and narrow-gauge tracks |
From a structural perspective, GB/T 22kg and JIS 22kg rails are highly similar and often interchangeable in industrial rail layouts when fastening systems are compatible. However, DIN crane rails such as A55 or A65 have wider bases and thicker webs, optimized for crane wheel loads rather than rolling mine carts. Therefore, selection must consider not only rail weight but also vehicle wheel profile and fastening design.
As a professional rail fastener supplier, GNEE RAIL can provide different standard steel rail such as GB,American, BS, UIC, DIN, JIS, Australian and South Africa which used in railway lines, cranes and coal mining.
