What is the standard size of a GB 60kg rail
Sep 29, 2025
Chinese standards defined standards for light rail, heavy rail, and crane rail for railways in China. The light rail is less than or equal to 30kg/m. The heavy rail is more than 30kg/m.
The GB 60 kg heavy rail is a typical heavy rail type specified by the Chinese National Standard (GB 2585-2007), indicating its theoretical weight is approximately 60 kg/m.

Different steel mills are allowed minor tolerances during production, but the overall dimensional range strictly complies with the GB 2585-2007 standard. GNEE RAIL can provide customization services according to customer requirements.Send your special customization requirements to GNEE.
The GB 60 kg heavy rail belongs to the "heavy rail" series, featuring a large cross-section and high strength. It is commonly used in high-speed railways, mainline mixed passenger and freight traffic, heavy-haul freight lines, and port dedicated lines – all scenarios requiring high stability. Its wider rail base and rail head design enhance bending resistance and fatigue performance, enabling it to withstand heavy axle loads and high-frequency impacts.
GNEE RAIL routinely supplies various rail specifications conforming to international standards such as GB, UIC, and AREMA, including models like 43 kg, 50 kg, 60 kg, 75 kg, as well as UIC54, UIC60, AREMA 115RE, and 132RE. We can provide customized processing services based on customer needs, including fixed-length cutting, drilling, end grinding, and anti-corrosion coatings, meeting the diverse requirements of railway construction and industrial tracks in different countries.
