15kg rail is a light steel rail manufactured to the GB standard, designed for low to medium load rail systems. It is widely used in industrial transport lines, mining tracks, yard railways, and temporary rail layouts.
Compared with lighter rail sections, the 15kg rail offers better strength and stability while keeping installation simple and cost-efficient. It works well with steel or wooden sleepers and suits short-distance hauling, trolley systems, and light-duty rail vehicles.
The table below outlines the standard dimensions of the 15kg rail, a lightweight rail section commonly used in mining tracks, tourist and scenic railways, and internal factory transport lines.
| Type of Rail | Standard | Dimensions mm | Steel Grade | Mass M | |||
| Height | Base Width | Head Width | Web Thickness | kg/m | |||
| 15kg | GB/T 11264-2012 | 79.37 | 79.37 | 42.86 | 8.33 | Q235B, 55Q | 15,2 |
The 15kg rail is offered in Q235B and 55Q steel. Q235B suits standard light-duty lines with lower impact, while 55Q provides higher strength and wear resistance for mining and frequent-use tracks.

We supply 15kg rails directly from our own stock, with standard 6m and 10m lengths ready for dispatch. Keeping inventory on hand allows us to support urgent project schedules and reduce lead times—especially for mining sites, industrial transport lines, and temporary rail systems where downtime is not an option.
Each 15kg rail is produced to GB/T 11264 standards and inspected before shipment to ensure consistent dimensions and material quality. With flexible order quantities and customization support, we make it easy to source reliable light rails without overpaying or waiting weeks for production.
For export shipments, 15kg rails are packed and loaded to maximize container space while ensuring safe transport. Standard 6m and 10m rail lengths can be loaded into both 20ft and 40ft containers using optimized stacking methods. Each bundle is securely strapped and protected at the ends to prevent movement, bending, or surface damage during ocean and inland transport. With extensive export experience, we ensure smooth container loading and reliable delivery to mining and industrial projects worldwide.
Send us your project details, required length, material grade, and quantity. Our team will get back to you quickly with pricing, lead time, and technical support—so you can move forward with confidence.
