Chinese Standard 38kg Heavy Steel Rail

38kg heavy steel rail is a type of rail commonly used in railway systems, with a unit weight of 38 kg per meter. Due to its large load-bearing capacity and high strength, 38kg heavy rail is usually used to carry heavy loads, long-term operation, and high-frequency transportation needs, especially for heavy-duty railways, freight railways, and some high-speed railway systems.

The unit weight of 38kg rail refers to the weight of 38 kg per meter of rail. Compared with lighter rails (such as 22kg or 30kg rails), 38kg rails are more suitable for railway systems that carry heavier loads and larger traffic flows.

38kg rails are usually made of high-strength alloy steel or carbon steel, and undergo special heat treatment processes to enhance their strength, wear resistance, and corrosion resistance. Common materials include high-quality carbon steel or alloy steel, which can provide long-term service life in various environments.

Parameters of 38kg Heavy Rail

Structural features
 

1.Rail cross-section design:

38kg rails usually adopt a wide rail head and bottom design to enhance the stability of the rails. The rail head is wider and can withstand more pressure from trains to avoid deformation caused by excessive pressure.

2.Hardness and wear resistance:

In order to increase the service life of the rails, 38kg rails are usually subjected to special heat treatment to make their surface hardness higher and have stronger wear resistance and corrosion resistance. This ensures that the rails are not easily damaged under long-term and frequent use.

3.Roadbed combination:

38kg rails are usually used with concrete roadbeds or gravel roadbeds. This roadbed can effectively support the rails, disperse the pressure exerted on the track when the vehicle passes, and improve the stability and comfort of the track.
