Railway Fasteners Customized Surface QT500-7 Railway Shoulder
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.
This type of rail shoulder is produced by hot forging, used together with clip bolt and special rail clip to fix the rail. The material can be low carbon steel and mid carbon steel, according to our customers' requirement.
