Rail shoulder is cast in the concrete rail ties to fix the elastic rail clips. There are two types of rail shoulders available, the cast-in shoulder and the weld-on rail shoulder, both of which are used for the fixing of elastic rail clips.
The casting shoulders as the embedded part of the railway fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail. The cast in shoulder is made by casting from iron, such as, GB/T 1348-1988, NF EN 1563(1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293(1985) or BS EN 1563(1997).

The weld-on shoulder is used at the typical position of rail where the rail shoulder is weld on flat steel plate rather than the standard railroad tie plate. The weld-on shoulder is produced by hot forging, according to AREA standard. The materials for weld-on shoulders production can be low or mid carbon steel, based on the customer’s requirements.
The above rail shoulder design is available for almost all rail sizes, with material made from low carbon steel.
