GB heavy rail is a heavy rail that complies with China's national standard (GB). It is mainly used for important lines such as trunk railways, heavy-load railways and high-speed railways. Its rail type is usually more than 50 kilograms per meter.

QU70 is a crane rail with a height of 120mm, a bottom width of 120mm, a head width of 70mm, a waist thickness of 28mm, and a theoretical weight of 52.77kg/m.

QU70 rail is a crane rail with a rail height of 120mm, a bottom width of 120mm, a head width of 70mm, a waist thickness of 28mm, and a theoretical weight of 52.8kg/m.

Crane rails are mainly used for laying crane trolley and trolley tracks, and are suitable for gantry cranes in large projects, container hoisting at docks, and other places.

GB/T 2585 is the current national standard for hot-rolled rails for railways. P38 38kg rails are one of the specifications of rails.

QU70 rails are crane rails that comply with the national standard YB/T5055. They are mainly used for laying crane trolley and car tracks.

Crane QU70 track is a type of track commonly used in cranes, with certain high hardness characteristics

Heavy rail steel has high tensile strength and yield strength, and can withstand the huge weight of the train and the dynamic load generated during operation, ensuring that the track will not be excessively deformed or broken during long-term use.

GB heavy-duty railway rails are mainly used in national trunk railways, heavy-duty railways, high-speed railways, and subway lines in urban rail transit.
