QU Crane Rail
Qu Crane Rail Supplier - Customized for Cranes
Qu crane rail refers to heavy-duty, hot-rolled crane rails complying with YB/T 5055-2014, designed for industrial and port applications with load capacities up to 500 tons, featuring flat-bottomed profiles (e.g., QU70, QU100), high-strength materials U71Mn (880 MPa tensile), and compatibility with Chinese crane systems while offering cost-effective alternatives to DIN 536 or EN 13674-1 standards.
Model Variants
QU Series: QU70, QU80, QU100, QU120 (QU denotes rail head width in mm).
Custom Lengths: Available in standard 12-meter segments or project-specific dimensions (e.g., container-friendly 11.5 m).
