What’s steel rail?

 1. What’s steel rail?

Steel rails are the load-bearing and guiding elements in a railway or crane track. The train rail profile is an asymmetrical I-beam with a wide flat bottom that fits on the railroad track. Steel rail profiles consist of a head at the top. The web supports the head and is comparatively thinner. At the base of the component is the foot that rests on the track.

Wheels rest on top of the rail, with wheel flanges extending downwards on the insides of the rails. The devices are produced in fixed lengths with end-to-end joints creating a continuous surface. One method of linking the sections is bolting them together using fish plates.

2. Application

Steel rails are employed in a broad spectrum of transportation functions, outlined by the following categories:

Mass transit—passenger railways, underground rail, trams.

Freight and logistics—bulk material transport.

Cranes, fixed track lifting equipment, for short haul and high load transport.

3. Types

There is light rail and heavy rail. Light rail and heavy rail are classified by the weight per meter of rail. The light rail weighs below 30kg/m, while the heavy rail above 30kg/m. Light rail usually include 8kg, 15kg, 18kg, 22kg, etc. Heavy rail includes 38kg, 43kg, and so on.

What is the crane rail? As its name suggested, the crane rail is used in the crane railway. The crane rail has its own material, dimensions, standard, and sizes. Normally, crane rail with a thicker web.

4. Specification

Different countries have different demands for the profiles and materials of steel rail, like DIN, EN, YB GB, JIS, ASTM, etc.

5. Material

The steel rail is made of steel alloy, which contains various chemical components. Why? The iron is not stable enough to sustain the train or crane. The addition of chemical components, like Mn, improves the chemical or physical performance of the final products.
