Description
Railroad rail, also known as the railroad track or railway track, is the main part of a railroad. Its function is to provide a continuous, smooth, and least resistance rolling surface for the trains to move forward. Most modern railways use continuous welded track (CWR) to make trains travel faster with less friction. The railroad rail is bearing great pressure when trains pass by. The pressure is transferred to the sleeper, ballast, and underlying subgrade. Railway fasteners keep rails in their place to make a safe running. Railroad rails are applied in high-speed tracks, light transport, heavy load tracks, trams, subways, factories, mining tracks, hauling tracks in forested areas, and other industrial fields. In the electrified railway or automatic block section, the rail can also be used as a track circuit.
Each country in the world has its standards for the production of rails, and the classification methods are not the same. In China, railroad rail is typed into light rail, heavy rail, and crane rail according to the weight of kg per meter.
12KG Light Rail
12kg light steel rail is widely used for mining industry, engineering machinery,factory, plant and so on.
