24kg rail is a medium-duty steel rail type specified under GB/T 11264-2012, with a nominal weight of 24.46 kg/m. It is intended for low-speed, medium-load track systems where durability and cost control matter. Typical uses include underground mine haulage, surface mining lines, factory and workshop railways, and temporary or auxiliary tracks.
The rail profile provides stable wheel guidance while keeping material consumption reasonable. Available in Q235B or 55Q steel, the 24kg rail suits projects that require dependable performance without moving to heavier rail sections.
The following table lists the standard cross-section dimensions of the 24kg rail defined by GB/T 11264-2012. These measurements control wheel contact, load transfer, and track stability in medium-load applications. Engineers and buyers use them to confirm compatibility with mine cars, fastening systems, and existing track layouts before selection or installation.

The 24kg rail supports medium-duty mine traffic without the cost and handling burden of heavier sections. It fits ore cars, service trolleys, and small locomotives used on daily haulage lines. Many sites choose it when 18kg feels light and heavier rails add no real benefit.
This rail profile keeps wheels aligned on straight runs and shallow curves. It performs well on jointed track with standard fasteners and fishplates. Operators see fewer alignment issues on uneven ground and less corrective work during routine maintenance.
The 24kg rail works across underground and surface areas with changing layouts. Crews cut, drill, and adjust it on site as mining faces move. This flexibility helps projects extend track length or reconfigure routes without replacing the entire line.
GlorySteelWork supplies 24kg rails for mining and light industrial projects with stable production and flexible order support. We work with project-based quantities, from small trial orders to long-term supply, and keep lead times predictable.
We offer Q235B and 55Q rail options, along with length cutting, drilling, and related rail accessories. Customers can source rails and matching components together, which simplifies procurement and reduces coordination on site.
Our team works closely with overseas buyers on specifications, packing, and export documents. With experience in mining rail shipments, we focus on delivering rails that match site requirements.
We ensure safe and efficient shipping of 24kg rails with protective packaging and precise loading. Depending on the length and quantity, we use forklifts or cranes for loading, ensuring stability during transport.
For export shipments, we typically use 20GP/40GP containers. The 6-meter rails fit perfectly into a 20-foot container, while longer lengths (8m or 10m) are loaded into 40-foot containers. We offer customized packing options to meet specific project requirements.
