Product Description
A rail shoulder is a pre-inserted item in concrete sleepers, available in single or twin stem types, used to fix 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
Made from cast iron, these are pre-embedded in concrete sleepers. Materials include M.C.I. (malleable iron) and S.G.C.I. (spheroid graphite iron). Other available materials include QT600-3, QT700-2, ZG25, ZG35, and ZG45.
Standards: GB/T 1348, NF EN 1563, ISO1038, DIN 1693, JIS G5502, KS D 4302, GOST 7293.
Weld-on & Special Shoulders
Weld-on shoulders are manufactured via hot forging. They are ideal for locations where standard sleepers cannot be used, allowing shoulders to be welded onto flat steel base plates (AREMA standard). Special shoulders are also produced via hot forging for use with rail clip bolts and low/mid carbon steel clips.
