Steel rails, also known as railway rails and rail tracks, are the main components of railway tracks. Its function is to guide the wheels of the locomotive, bear the huge pressure of the wheels, and maintain the stability of railway transportation. The rails must provide a continuous, smooth and minimal rolling surface for the wheels. Rails can also be used as track circuits in electrified railways or automatic blocking sections.

my country's rails are divided into crane rails, heavy rails and light rails.
Heavy rails are 38kg, 43kg, 50kg, 60kg and 75kg. Also known as P38 rail, P43 rail, P50 rail, P60 rail, P75 rail.
Heavy rail is mainly used for the laying of temporary transportation lines and light locomotive lines in tunnels, seaports, factories and construction sites.
