TB 50kg rails are manufactured in strict accordance with the Chinese railway industry standard TB/T 2344. Compared to standard rails, TB 50kg rails feature a superior profile design, stricter tolerance control, and higher fatigue resistance. They are suitable for high-intensity, heavy-haul transportation.
