What is the Dimensions of a 75kg heavy rail

GB 75 kg/m heavy rail is one of the GB standard heavy rails, designed to withstand high wheel loads and long-term operation of heavy trains.

Produced strictly according to GB standards, the GB 75 kg rail has a rail height of approximately 172 mm, a head width of 75 mm, a web width of 16 mm, a base width of 150 mm, and a foot thickness of about 20 mm. This thickened and widened cross-section provides significant advantages in longitudinal bending strength and fatigue resistance while enhancing lateral track stability, making it ideal for high-speed railways, heavy-load mainlines, and frequently operated railway lines.

The unit weight of the 75 kg rail is 75 kg per meter, with standard lengths of 12 m, 18 m, or continuous welded rails. During construction and operation, the rails are used in conjunction with , rail clips, and bolt systems to form a complete railway fastening system, ensuring rail positioning accuracy and gauge stability, while effectively absorbing impacts and vibrations from passing trains, thereby extending the service life of sleepers and the track system.

In practical applications, 75 kg heavy rails can be cut, drilled, end-face ground, or treated for corrosion resistance to meet different railway engineering and industrial track requirements. Their high load capacity and durability make them widely used in high-speed rail, freight mainlines, and heavy-duty industrial tracks.
