Product Description

Rail shoulder, also called rail iron shoulder, is mainly used to be casted in the concrete ties to fixate elastic rail clips. According to the shape, it can be classified into Single Stem Rail Iron Shoulder and Twin Stems Rail Iron Shoulder. Besides, according to the manufacturing ways, rail shoulder can be divided into 3 types: casting rail shoulder, weld-on rail shoulder and hot forging rail shoulder.

The rail shoulder is embedded in concrete at the time of casting, it's used to grips the clip effectively and provides lateral support to rail.

The Rail shoulder is semi-embedded part cast in the concrete rail ties to fix the elastic rail clip to the base plate. There are two Common types of rail shoulders available: Cast-in Shoulder and Weld-on Shoulder, both of which are used for the fixing of elastic rail clips. One is Single Stem Iron Shoulder used in pre-stressed concrete ties and the other is Twin Stem Iron Shoulder used in Bi-Block or Twin Block concrete ties.

Quality Control System

All processes are in accordance with the requirements of ISO quality management system, from supplier quality control to finished products. We maintain a strict quality control system:

Raw Material Inspection: Before producing Rail Shoulder, we check and test chemical composition and mechanical properties.
Batch Testing: Inspectors take sample sampling and batch testing after manufacturing, providing raw material certificates.
Physical & Chemical Testing: We perform corresponding inspection based on specific requirements to ensure standards are met.
Final Coordination: We organize quality control meetings and provide technical guidance to ensure qualified products are delivered.
