Plain Inserts / Casting Iron Rail Shoulder In Concrete Sleepers
General Introduction of Railway Iron Shoulders
Inserts/Iron Shoulders are cast in the concrete ties for fixation of Elastic Rail Clips. Our Iron Shoulders are
manufactured from pearlitic malleable iron and spheroid graphite iron. We offer two types of Iron Shoulders:
Single Stem Iron Shoulders mostly used in pre-stressed concrete ties, and Twin Stem Iron Shoulders
commonly used in Bi-Block or Twin Block concrete ties.
