Product Introduction
As a highly reliable industrial component, the GB QU series rails can effectively resist the overturning moment during crane operation and ensure the safety of equipment operation through reasonable cross-sectional inertia moment design.
The GB QU series high-hardness crane rails are rails specially used for crane operation. The manufacturing process usually includes heating the steel billets that meet the requirements, rolling them into shape through multiple rolling processes, and then performing heat treatments such as quenching and tempering to further improve the hardness, strength and wear resistance of the rails. Finally, surface treatments such as shot peening are performed to improve surface finish and residual compressive stress, and enhance fatigue resistance and corrosion resistance.

Product Application
QU series crane rails are mainly used for crane rail laying in large-scale projects, docks, factories and other places. Especially in some occasions where heavy objects need to be lifted frequently and the bearing capacity and wear resistance of the rails are required to be high, QU series high-hardness crane rails can better meet the use requirements.
GNEE RAIL is a leading exporter of crane rails in China. We focus on the production and international trade of GB QU series high-hardness crane rails. Relying on the advantages of China's steel industry, the company strictly produces QU70, QU80, QU100, QU120 and other high-specification crane rails in accordance with the national standard YB/T 5055. It adopts a fully automatic rolling production line equipped with ultrasonic flaw detection and dimensional accuracy detection systems. The products have passed ISO9001 quality management system certification.
