What does JIS stand for?
It is Japan's national standard system that specifies the technical requirements, testing methods, dimensions, tolerances, and quality control rules for industrial products, including steel, railway materials, machinery, and construction products. In the steel and railway industry, JIS standards are widely used for steel rails, rail fasteners, baseplates, fishplates, bolts, and structural steels, ensuring consistent quality and interchangeability in engineering projects.
In railway applications, JIS standards such as JIS E (railway engineering) and JIS G (ferrous materials) define the performance and manufacturing requirements for track components. GNEE RAIL supplies JIS-compliant steel rails and complete railway fastening systems, and also supports GB, EN/UIC, BS, DIN, and AREMA standards to meet the needs of international railway, metro, mining, and crane rail projects.

Specifications of JIS Standard Steel Rails
- JIS E 1101: (Main types 50N, 60N, 70N, 37KG, 50KG,etc) is the most core standard, which specifies the rails that are mainly used for carrying heavier loads in railway main lines, branch lines, station lines, special lines for factories and mines.
- CR73/ CR100: Specially used in factories, warehouses, wharves and other places of the bridge, gantry crane running rail.
- JIS E1103: (Main models 9kg, 12kg, 15kg, 22kg, 30kg,etc) Used in underground mines, ground narrow-gauge transport, small transport vehicles inside factories, temporary rails and other light-loaded, low-speed transport scenarios

Interchangeability Between GB 22kg Rail and JIS 22kg Rail
In some international projects, clients may encounter 22kg/m light rails under both China's National Standard (GB/T 11264) and Japan's Industrial Standard (JIS E 1101). Our comparison shows that the 22kg rails under these two standards have identical cross-sectional dimensions, including:
- Head Width
- Base Width
- Rail Height
- Web Thickness
| 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 | |
Therefore, in most application scenarios, GB 22kg mining rails and JIS E 22kg rails can be fundamentally interchanged, especially suitable for the following situations:
- Requiring more flexible procurement alternatives
- Coordinating multi-national supply chains
- Temporary maintenance or partial replacement scenarios
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.
