🛠️ 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

The manufacturing process adheres to strict quality management requirements. All processes are in accordance with ISO quality management systems, from supplier quality control to finished products.

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

Manufacturing Inspection: Quality control inspectors take sample sampling and batch testing after the manufacturing process, providing raw material certificates to control the testing process.

Physicochemical Testing: According to different requirements, we conduct corresponding physical and chemical inspections. Materials are only accepted if they strictly meet our standards.

Guidance & Coordination: We organize quality control coordination meetings and provide technical advice to external suppliers to ensure qualified products are delivered.
