Product Introduction

Plain Surface Cast Iron 5.6 Grade Rail Shoulders are essential components cast directly into concrete ties to facilitate the secure fixation of Elastic Rail Clips. These shoulders are precision-engineered from high-quality materials including pearlitic malleable iron (M.C.I. Inserts) and spheroid graphite iron (S.G.C.I. Inserts).

We provide two primary configurations: Single Stem Iron Shoulders, typically utilized in pre-stressed concrete ties, and Twin Stem Iron Shoulders, which are standard for Bi-Block or Twin Block concrete tie systems. These accessories are tailored for specific rail sections to ensure optimal elastic clip toe loading and long-term track integrity.
