43kg heavy-duty steel rails are widely used for laying railway mainlines, dedicated lines, bends, and tunnels. Although it is referred to as a "heavy-duty" rail, in modern high-speed and heavy-duty railways, rails with weights of 50kg/m, 60kg/m, or even heavier are more commonly used. However, in some specific situations, such as routes with moderate speed and capacity, 43kg heavy-duty steel rails are still an economical and practical choice.
