Product Description

Rail shoulder, also known as rail iron shoulder, is a critical component cast into concrete ties to fixate elastic rail clips. These components are essential for maintaining track stability and alignment.

◈

Classification by Shape: Available in Single Stem Rail Iron Shoulder and Twin Stems Rail Iron Shoulder.

◈

Manufacturing Methods: Produced via casting, weld-on, or hot forging techniques to meet various technical requirements.

◈

Functional Design: Embedded directly into concrete during casting to grip clips effectively and provide lateral rail support.

Commonly utilized types include Cast-in Shoulders and Weld-on Shoulders. Single Stem variants are typically applied in pre-stressed concrete ties, while Twin Stem variants are designed for Bi-Block or Twin Block concrete ties.

Quality Assurance System

Our production follows strict ISO 9001 standards to ensure every rail shoulder meets international safety and durability requirements:

✔

Raw Material Inspection: Comprehensive testing of chemical composition and mechanical properties before production begins.

✔

Batch Testing: Systematic sampling and testing throughout the manufacturing process with full certification tracking.
