The rail shoulder, also known as the railway shoulder, is mainly used for pouring in the concrete sleeper to fix the elastic rail clip. We mainly produce two types of rail shoulders for rail clips: cast in shoulders and welded on shoulders.
Kingrail Parts can produce various rail screw dowels according to UIC, AREMA, GB, NF EN 1563(1997), DIN, JIS, BS and other standards.
Our Rail Anchors:
1. Cast-in Rail shoulder
As the embedded part of the rail fastening system, the casting-in shoulder is pressed into the concrete sleeper and assembled with E-type rail clip to fix the rail. Our raw material for casting-in rail shoulder is cast 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).
Application: UIC54, UIC60, 115RE,, 50kg rail, 60kg rail, BS80lbs, BS100lbs, etc.

2. Weld-on Rail Shoulder
In some places, standard railway sleepers cannot be used. Railways in these places cannot use standard tie plates. At this time, weld-on rail shoulder can be flexibly welded to non-standard non-standard rai tie plate. It is particularly useful and cost-effective in this case.
According to the AREMA standard, the weld-on rail shoulder is made by hot forging. The production material of weld-on rail shoulder can be low carbon or medium carbon steel.
3. Hot Forged Rail Shoulder
Hot forged rail shoulders are made by hot forging, and used with low carbon steel or medium carbon steel materials together with rail clip bolts and special rail clip to fix the track.
