Product Description
A rail shoulder is a pre-inserted item in the concrete sleepers, no matter for single stem type or twin stem type, used to fix the elastic rail clips, mainly e-clips, within the fastening system. We are capable of producing two types of rail shoulders for rail clips: cast in shoulder and weld-on shoulder.
Casting Rail Shoulders
Cast in Shoulder is made by casting from iron, and such shoulder is used by being pre-embedded in the concrete sleepers and works with the elastic clip to fasten the rail. Material types include M.C.I. shoulder by malleable iron and S.G.C.I. shoulder by spheroid graphite iron. Additional materials available: QT600-3, QT700-2, ZG25, ZG35, ZG45, etc.
Standard: 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).
Weld-on Shoulder
Weld-on shoulder is made by hot forging, used where standard sleepers are unable to be easily used. They are welded onto flat steel base plates to fabricate rail retaining units on both steel ties and base plates, typically according to AREMA standards. Suitable for Pandrol style clips from 30lbs to 113lbs.
Special Rail Shoulder
Produced by hot forging for use with rail clip bolts and special rail clips, utilizing low or mid carbon steels.

Frequently Asked Questions
What are the primary functions of a rail shoulder?
A rail shoulder is pre-embedded in concrete sleepers to secure elastic rail clips (like e-clips), ensuring the rail stays firmly attached to the fastening system.
What materials are used for cast-in rail shoulders?
They are typically made from iron, including Malleable Cast Iron (M.C.I.) and Spheroid Graphite Cast Iron (S.G.C.I.), such as QT500, QT600, and QT700 grades.
When should a weld-on shoulder be used instead of a cast-in one?
Weld-on shoulders are used where standard concrete sleepers are not suitable, allowing the shoulders to be welded directly onto flat steel base plates or steel ties.
Can you provide components that meet international railway standards?
Yes, our products comply with major global standards including EN 1563, UIC 813, BS 5892, and AREMA standards.
What components make up a complete railway wheel set?
A standard wheel set consists of two wheels, one axle, and two bearings. It may also include gears or brake discs depending on the vehicle's technical requirements.
Do you support customized material requirements?
Absolutely. Beyond standard QT iron, we can produce components using ZG25, ZG35, ZG45, and other low or mid-carbon steels as per project specifications.
