The GB Standard 60kg rail (made of U71Mn / U75V) is one of the most widely used heavy-duty rails in China. It is extensively applied in high-speed railways, heavy-load mainline tracks, and industrial transport lines. Its high strength, wear resistance, and good toughness allow it to endure long-term, high-frequency train loads while maintaining track stability and safety.

Application of 60KG Rails
Heavy-Haul Railway Lines
GB 60kg rails are widely used on national trunk railway lines, particularly on heavy-haul freight lines for transporting coal, ore, and other bulk materials. Its strong bending resistance and fatigue durability make it an ideal choice for long-distance, high-load rail operations.
Port Crane Rail Runways
In port terminals, GB 60kg rails are widely adopted for gantry crane runways and container handling systems. Its wide base and robust profile allow it to withstand repetitive lifting loads and frequent trolley movements. Compatible with various rail clamp systems, ensuring long-lasting performance in demanding marine environments.
Industrial & Mining Railways
In steel plants and open-pit mining zones, GB 60kg rails are used for internal industrial railways, handling raw material shuttling and heavy-duty mining carts. It performs well under harsh conditions and minimizes maintenance requirements. GNEE RAIL suppor custom cutting, drilling, and bending available upon your request.
Crane Track Systems (Industrial Use)
In large industrial areas such as manufacturing plants and shipbuilding bases, overhead and gantry cranes often adopt 60kg steel rails as running tracks to bear the horizontal movement load of equipment. This type of steel rail, when used in conjunction with various rail clamps, base plates, and base systems, can be quickly installed on concrete foundations or steel structure foundations.
Temporary & Project-Based Rail Use
In hydropower station construction, tunnel projects, or large-scale infrastructure development, 60kg steel rails are often used for laying temporary tracks, facilitating the transportation of materials or the sliding of equipment. Due to their strong reusability and stable gauge, they are the preferred construction track profiles for project contractors.
Urban Rail Transit Systems
Although urban light rail systems mostly use light rails, in certain heavy-load sections (such as depot areas, track replacement zones on main lines, or heavy vehicle maintenance areas), GB 60kg steel rails are also selected to enhance load-bearing capacity and durability. This type of steel rail is compatible with the standard line structure of urban rail transit and has excellent system adaptability.
GNEE RAIL provides full supporting services, including rail processing, customized lengths, 45° mitre cuts, welding, and matched rail clips, fish plates, bolts, and rubber pads, ensuring each rail achieves optimal performance during installation and operation.
In addition to U71Mn and U75V materials, GNEE RAIL also offers P43, P50, P75 series heavy rails and QU series crane rails, meeting diverse customer requirements in railway transportation and industrial track applications.
