The JIS 22kg rail, manufactured under JIS E 1101-2001, weighs 22.3kg per meter. It provides a practical solution for small-scale material handling systems and auxiliary rail lines. Available in 55Q or Q235 steel, it balances cost and performance, making it suitable for workshops, warehouse lines, and mine tunnels.The rail's manageable size and stable quality make it a preferred option for light industrial track systems where space and budget are limited.

Specification of JIS 22kg Steel Rail
The JIS 22kg steel rail employs a classic I-beam cross-section comprising three critical components:
- Rail Head (50.80mm width): As the direct wheel contact surface, its precision-profiled contour ensures smooth rolling contact while optimizing friction characteristics for reduced wear.
- Web (10.72mm thickness): Functioning as the structural backbone, this vertical section withstands vertical compression forces and lateral shear stresses during vehicle operation.
- Base (93.66mm width): Engineered to distribute loads efficiently to the foundation, this broad platform delivers uncompromised system stability under dynamic loading conditions.

What is the difference between JIS 22KG Rail and GB 22KG Steel Rail in standards and profiles?
The first and most important difference lies in the standard systems and profile control. JIS rails follow Japanese Industrial Standards (JIS E series), while GB rails follow China National Standards (GB/T). Even when the weight per meter is the same, head width, web thickness, and foot width may differ slightly, which directly affects the compatibility with sleepers, baseplates, and clips.
Typical dimensional comparison (reference values):
| Standard | Rail Type | Height (mm) | Head Width (mm) | Foot Width (mm) | Weight (kg/m) |
|---|---|---|---|---|---|
| JIS | JIS 22KG Rail | ~93 | ~50 | ~93 | 22.3 |
| GB/T | GB 22KG Steel Rail | 93.66 | 50.8 | 93.66 | 22.3 |
Although these dimensions are close, fastening systems are usually designed around specific profiles, so mixed installation without checking drawings may lead to poor rail seat contact or uneven load transfer. In international mining and industrial projects, GNEE RAILWAY RAILWAY normally confirms profile drawings and fastening interfaces before recommending interchangeability.
As a professional rail fastener supplier, GNEE RAILWAY RAILWAY 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.
