The rail shoulder is a pre-placed metal component before the concrete sleeper is poured. It is mainly used to fix the elastic rail clips and railway track on the railway foundation. Rail shoulders are semi-embedded parts, which are mainly divided into two categories: embedded rail shoulders and welded rail shoulders, both of which are used to fix rail clips for railway fastening system.
Both the embedded rail shoulder and the welded rail shoulder are used to fix the rail by working with E rail clips.
In some places, standard railway sleepers cannot be used. The rails in these places cannot use the standard rai tie plate. At this time, the welded shoulder can be flexibly welded to the non-standard rai tie plate.
In addition, the shoulder can also be used for Pandrol rail fastening systems ranging from 30lbs to 113lbs.
1. When using E clip railway fastening systems to fix the rail, the railway shoulder welded to the rail sleeper firmly connects the sleeper and the rail.
2. The standard railway shoulder is generally poured in concrete sleepers. Generally, a more flexible welded railway shoulder is used at turnouts or railway crossings.
3. The welded railway shoulder is flexible and convenient to install, and can be welded in a relatively flexible position. It has very good economic benefits for the special situation in railway construction.
4. The standard embedded railway shoulder guarantees the normal transportation of the railway. The welded railway shoulder is flexible and convenient. Together, the two completed the railway fixing system.

Railway shoulder is usually made by hot forging, usually using low carbon steel or medium carbon steel as raw materials.
The rail shoulder produced by Kingrail Parts can meet various standards: UIC, AREMA, GB, NF EN 1563 (1997), DIN, JIS or BS. We can also produce rail shoulders according to customer drawings or samples.
