📝 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

Pre-Production Inspection: Before producing Rail Shoulder, we will check and test the raw materials. We require suppliers to provide production batch number, chemical composition, mechanical properties and other testing indicators.

Manufacturing Monitoring: Our quality control inspectors take sample sampling and batch testing after the process of manufacturing Rail Shoulder, and provide raw material certificate and other means to control the testing process.

Physical & Chemical Testing: According to the different requirements of Rail Shoulder, we make the corresponding physical and chemical testing and inspection. If the results do not meet our requirements, we will refuse to accept the materials.

Final Coordination: For semi-finished products and external suppliers, we often organize quality control coordination meetings and provide technical advice and guidance to ensure qualified products are delivered prior to shipment.
