The iron shoulder is cast in the concrete ties for fixation of elastic rail clips. Our rail cast iron shoulders include M.C.I. shoulder manufactured from pearlitic malleable iron and S.G.C.I. shoulder manufactured 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.
