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 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.

Cast-in Rail Shoulder
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). These are semi-embedded parts cast in the concrete rail ties to fix the elastic rail clip to the base plate.

Weld-on Rail Shoulder
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 tie plate. The production method is hot forging, fabricated according to AREA standard. The steel material type can be low or medium carbon steel. These are particularly useful for switch and crossing layouts where vertical rail geometry is employed.
Frequently Asked Questions
What is the primary function of a rail shoulder?
A rail shoulder is an embedded part used in concrete rail ties to securely fix elastic rail clips, ensuring the rail stays fastened to the sleepers.
What are the differences between Cast-in and Weld-on shoulders?
Cast-in shoulders are pressed directly into concrete sleepers during manufacturing. Weld-on shoulders are forged and welded onto flat steel plates, often used for specialized track layouts.
Which international standards do your rail shoulders meet?
Our products comply with various global standards including GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, and BS EN 1563.
What materials are typically used for production?
We use high-quality ductile iron (such as QT400-15, QT450-10, and QT500-7) for cast shoulders and low to medium carbon steel for weld-on shoulders.
What is your daily production capacity for rail shoulders?
Our facility has a robust production capacity of approximately 20,000 pieces per day to meet large-scale infrastructure demands.
Can these shoulders be used for switch and crossing layouts?
Yes, weld-on shoulders are specifically designed to be cost-effective and versatile for fabrication in switch and crossing layouts where vertical rail geometry is required.
