Products Description
50kg steel rail is a heavy rail commonly used in railway construction. Its standard model is named after its weight of 50 kg per meter. This type of rail is mainly laid on the main railway line and bears the weight of the train and the impact force during operation. Due to its excellent wear resistance and bending resistance, 50kg rail plays an important role in railway transportation.
Specifications
- Rail height: usually 152 mm, this height design can provide good stability and load-bearing capacity.
- Rail bottom width: generally 132 mm, the bottom width is crucial to the lateral stability of the rail.
- Rail head width: the standard width is 70 mm, and the rail head part bears the direct pressure of the train wheelset.
- Rail waist thickness: usually 15.5 mm or more to ensure sufficient strength and rigidity.
- Length: The standard length of the rail is usually 12.5 meters, which is convenient for transportation and on-site laying.
