Product Description

Rail shoulder, also known as a rail iron shoulder, is a vital component cast into concrete ties to fixate elastic rail clips. Based on design, they are categorized into Single Stem and Twin Stem variants. Manufacturing methods include casting, weld-on, and hot forging processes.

Embedded during the casting of concrete rail ties, these shoulders effectively grip the clip and provide essential lateral support to the rail structure. We provide two primary types of rail shoulders: Cast-in Shoulders and Weld-on Shoulders.

Single Stem Iron Shoulder: Typically utilized in pre-stressed concrete ties.
Twin Stem Iron Shoulder: Optimized for Bi-Block or Twin Block concrete ties.

Quality Control Process

1

Raw Material Inspection: Before production, all raw materials are tested for chemical composition and mechanical properties. Batch numbers are strictly tracked.

2

Batch Sampling: Inspectors perform sampling and testing during and after the manufacturing process to ensure consistent quality.

3

Physical & Chemical Testing: Specialized inspections are conducted based on specific product requirements. Non-compliant materials are strictly rejected.

4

Technical Coordination: We maintain strict quality management through coordination meetings and technical guidance to ensure only qualified products reach the customer.
