U71Mn QU80 GB Crane Steel Rail

U71Mn QU80 crane rails are medium-duty, heavy-duty rails that comply with the Chinese national standard (GB/T 2585). They are widely used in bridge cranes, gantry cranes, and port loading and unloading systems.

Made from high-manganese steel U71Mn, these rails offer excellent wear and impact resistance, maintaining excellent stability and service life in high-frequency start-stop and heavy-load operating environments.

not only provides QU80 national standard crane rails, but also crane rails in various specifications, including QU70, QU100, and QU120, along with supporting rail clamps, rail pads, bolts, and fishplates, to meet the installation needs of various lifting equipment.

QU80 crane rails have cross-sectional dimensions of 80mm head width, 130mm rail height, 130mm base width, and 28mm waist thickness. The unit weight per meter is approximately 63.69kg. This rail type contains 1.1%–1.3% manganese in its chemical composition, ensuring high toughness even under severe impact. Through hot rolling and finishing processes, the U71Mn QU80 rail achieves exceptional dimensional accuracy and surface quality, fully complying with Chinese national standards. It undergoes multiple non-destructive testing to ensure safety.

QU80 crane rails are widely used in medium-load applications, such as bridge crane rails in factory workshops, gantry crane rails at container terminals, and operating rails for mining equipment. Their superior mechanical properties ensure stable gauge and smooth operation in diverse environments.

All U71Mn QU80 national standard crane rails are coated with anti-rust oil before leaving the factory and packaged using wire lashing or steel palletized packaging to prevent deformation and corrosion during transportation. GNEE RAIL offers a variety of international shipping methods, including full container load (FCL), bulk cargo, and rail transport, flexibly meeting customer delivery and cost control requirements and ensuring the safe and rapid arrival of products.
