🛠️ Product Description
A rail shoulder is a pre-inserted item in the concrete sleepers, used to fix the elastic rail clips (mainly e-clips) within the fastening system. We produce two primary types: cast-in shoulders and weld-on shoulders.
Casting Rail Shoulders
Cast-in shoulders are made from cast iron and are pre-embedded in concrete sleepers. Available materials include M.C.I. (malleable iron) and S.G.C.I. (spheroid graphite iron). We also offer QT600-3, QT700-2, ZG25, ZG35, and ZG45.
Standards: GB/T 1348-1988, NF EN 1563, ISO1038, DIN 1693, JIS G5502, KS D 4302, GOST 7293, or BS EN 1563.
Weld-on Shoulder
Made by hot forging, these are used where standard sleepers are impractical. They are welded onto flat steel base plates to fabricate rail retaining units on steel ties and base plates, typically following AREMA standards. Suitable for Pandrol style clips (30lbs to 113lbs).
Special Rail Shoulder
Produced by hot forging, these are used with rail clip bolts and special clips for fastening rails using low or mid-carbon steels.
