The 12kg rail, also known as a 12kg/m light mining rail, is a lightweight steel rail manufactured to the Chinese national standard GB/T 11264-2012. Designed for temporary tracks, mining transport, and light industrial applications, it offers a practical, cost-effective solution for short-distance rail systems and low-load operations.
Constructed from high-quality Q235B steel, the 12kg rail features a stable cross-section, optimized head and web dimensions, and precise tolerances to ensure reliable performance and long service life. Its compact size and low unit weight make installation fast and maintenance simple, while compatibility with standard fishplates and fasteners ensures secure track connections.
The 12kg rail features a standardized cross-section designed to meet the requirements of light mining rail systems. The following dimensions are manufactured in accordance with GB/T 11264-2012, ensuring consistent geometry and reliable track alignment.
| Type of Rail | Standard | Dimensions mm | Steel Grade | Mass M | |||
| Height | Base Width | Head Width | Web Thickness | kg/m | |||
| 12kg | GB/T 11264-2012 | 69.85 | 69.85 | 38.1 | 7.54 | Q235B | 12.2 |
The material selection of the 12kg rail focuses on balanced strength, formability, and weldability for light-duty applications. The table below lists the standard steel grade used for this rail type, along with its key mechanical properties and Chemical Composition.
