Product Description

Standard:GB,ASTM,EN,JIS

The cross-sectional shape of the rail is made of the I-shaped cross section with the best bending resistance, the track head, the waist and the bottom of the rail. In order to make the rails better from all aspects of the force to ensure the necessary strength conditions, the rail should have sufficient height, the head and bottom should have sufficient area and height, the waist and the bottom should not be too thin.

Application Scope

The rail is the main component of the railway track. Its function is to guide the wheels of the locomotive forward, bear the enormous pressure of the wheel, and passed to the sleeper. The rails must provide a continuous, smooth and resistant rolling surface for the wheels. In the electrified railway or automatic block section, the rail can also be used as a track circuit.
