Products Description
The types of steel rails are generally classified based on the weight of each meter of steel rail. A 43kg heavy-duty rail means that the mass of each meter of rail is 43 kilograms.
According to weight, steel rails are divided into light-duty rails, heavy-duty rails, and crane type rails. Steel rails weighing 38 kilograms or more per meter are called heavy-duty rails; The 43kg steel rail is a secondary heavy rail.

Other Features
The main materials of 43kg heavy-duty steel rails include 50Mn and U71Mn. These materials have good mechanical properties and wear resistance, which can meet the needs of railway operation.
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.
