Product Description
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 rail way fastening system are pressed in concrete sleeper and work together with the E clip to fasten the rail.

Types of Rail Shoulder
The Rail shoulder is a semi-embedded part cast in concrete rail ties to fix the elastic rail clip to the base plate. There are two common types of rail shoulders available: Cast-in Shoulder and Weld-on Shoulder.
Cast-in Rail Shoulder
Cast in shoulders are made from iron casting, following standards such as GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, KS D 4302, GOST 7293, or BS EN 1563.

Weld-on Rail Shoulder
Weld-on shoulders are used where the shoulder is welded on flat steel plates instead of standard tie plates. These are produced via hot forging and fabricated according to AREA standards. They are particularly cost-effective for switch and crossing layouts where vertical rail geometry is employed.
Frequently Asked Questions
What is the main function of a rail shoulder?
The rail shoulder is used to fix elastic rail clips to the base plate or concrete ties, ensuring the rail remains securely fastened within the railway system.
What is the difference between cast-in and weld-on shoulders?
Cast-in shoulders are embedded directly into concrete sleepers during casting, while weld-on shoulders are welded onto steel plates or sleepers, offering flexibility for switch and crossing layouts.
Which materials are commonly used for rail shoulders?
Common materials include ductile iron grades such as QT400-15, QT450-10, and QT500-7, as well as low or medium carbon steel for forged weld-on types.
What standards do your rail shoulders comply with?
Our products meet various international standards including GB/T 1348, ISO1038, DIN 1693, JIS G5502, and BS EN 1563.
Can weld-on shoulders be used for specific custom designs?
Yes, the ability to weld them in specific positions makes them highly useful and cost-effective for custom switch layouts and vertical rail geometry.
What is the typical production capacity for these components?
The production facility has a capacity of approximately 20,000 pieces per day to meet large-scale infrastructure demands.
