Introduction and application 
Steel rail, also called rail track, steel track, is the main component of railway track. Its function is to guide the wheels of the locomotive, bear the great pressure of the wheel, and keep the stability of railway transportation. The rail must provide continuous, smooth and minimum rolling surfaces for the wheels. In electrified railway or automatic block section, rail can also be used as an orbital circuit.
 
The steel rail in china are divided into Crane rail, Heavy rail and light rail. 

Regarding heavy rail, there are 38kg, 43kg, 50kg, 60kg and 75kg. 

The Heavy rail is mainly used for the laying of temporary transportation lines and light locomotive lines for tunnel, seaport, factories and construction sites.
