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 for all production stages:

Before producing Rail Shoulder, we check and test raw materials, requiring production batch numbers, chemical composition, and mechanical properties.

Our quality control inspectors perform sample sampling and batch testing after manufacturing, providing raw material certificates to control the process.

Physical and chemical testing is conducted according to specific requirements. Materials are only accepted if they meet strict standards.

We organize quality control coordination meetings and provide technical guidance to ensure qualified products are delivered to customers.

Frequently Asked Questions

Q1: What is the primary function of a rail shoulder?

The rail shoulder is used to fixate elastic rail clips and provide lateral support to the rail by being cast into concrete ties.

Q2: What are the main types of rail shoulders based on manufacturing?

Rail shoulders are generally divided into three manufacturing types: casting rail shoulders, weld-on rail shoulders, and hot forging rail shoulders.

Q3: What is the difference between Single Stem and Twin Stem shoulders?

Single Stem Iron Shoulders are typically used in pre-stressed concrete ties, while Twin Stem Iron Shoulders are used in Bi-Block or Twin Block concrete ties.

Q4: What certifications do your rail shoulders meet?

The products and processes are ISO 9001 certified, ensuring high-quality management and standardized production procedures.

Q5: How is the quality of the raw materials verified?

Suppliers must provide batch numbers, chemical composition, and mechanical properties, which are then tested and checked by inspectors before production begins.

Q6: How are the products packaged for transport?

Rail shoulders are typically packaged in bundles using steel wire rods to ensure stability and safety during transit.
