The iron
shoulder is pre-inserted in the concrete tie. There are M.C.I. shoulder
manufactured from malleable iron and S.G.C.I. shoulder manufactured from malleable
iron and S.G.C.I. shoulder from spheroid graphite iron. We offer two types of
iron shoulders. One is Single Stem Iron Shoulder used in pre-stressed concrete
ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block
concrete ties.

We can
also provide Weld-on shoulder is used for the typical position of rail. This
rail cast iron shoulder is welded on flat steel plate instead of the standard
tie plate and is produced according to AREA standard. Designed for use with E
style elastic rail clips, the weld on shoulder fastening allows customers to
fabricate rail retaining units on both steel sleepers and steel base plates.

We are a
leading rail shoulder manufacturer in China. We can also make other rail
fastenings such as railway screw, plastic dowel, rail pad, railway insulator,
rail fish bolt, railway base plate, rail anchor, railway shoulder, rail bolt,
flat and spring washer, fastening system of E type/SKL type/KP type/Nabla type
