National standard U75V fatigue-resistant heavy rail is a railway track material with specific properties and standards.

GB heavy rails with high quality welding performance refer to heavy rails that meet national standards and have good welding performance.

GB QU70 indoor crane track is a track that complies with national standards and is specially used for indoor crane operation.

GB extra heavy crane rail QU120 is a special crane rail that meets national standards.

GB heat-treated QU crane rails refer to QU series crane rails that have been heat-treated and meet Chinese national standards. QU series crane rails include QU70, QU80, QU100, QU120 and other specifications.

The ultra-high strength and fatigue-resistant 75kg/m national standard heavy rail is a high-performance rail specially used for railway tracks.

GB heavy rail refers to heavy steel rail that meets China's national standards. It is mainly used for railway track laying, and can bear the high load and frequent impact of train operation. It is a core component of railway infrastructure.

The advantages of GB heavy rails are their high strength and high wear resistance. Compared with ordinary rails, they can withstand greater train axle weights and higher operating speeds, significantly extending their service life.

The rail design of GB crane rails conforms to ergonomics and crane operation principles, which helps to reduce vibration transmission during crane operation, reduce the impact on plant structures and surrounding equipment, and create a relatively stable working environment for operators.

QU70 GB crane track is a type of track commonly used for large cranes, mainly used for large projects, dock lifting containers, etc.
