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. It is a 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 Process

1

Raw Material Inspection: Before producing Rail Shoulder, we check and test the raw materials for chemical composition and mechanical properties.

2

Batch Testing: Quality control inspectors take sample sampling and batch testing after manufacturing to ensure standard compliance.

3

Physical & Chemical Analysis: We conduct rigorous testing. If results do not meet standard requirements, materials are strictly refused.

4

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

Frequently Asked Questions

What is the primary function of a rail shoulder?

The rail shoulder is primarily cast into concrete ties to fixate elastic rail clips, providing essential lateral support to the rail and ensuring stability.

What are the different types of rail shoulders available?

There are three main manufacturing types: casting rail shoulders, weld-on rail shoulders, and hot forging rail shoulders. They also come in single stem or twin stem designs.

Can the rail shoulders be customized?

Yes, we provide customized rail shoulders based on specific drawings, dimensions, and technical requirements to fit different rail systems.

How do you ensure the quality of the rail shoulders?

All processes follow ISO 9001 standards. We perform rigorous raw material testing, batch sampling, and physical-chemical inspections before shipping.

What is the difference between single and twin stem shoulders?

Single stem iron shoulders are typically used in pre-stressed concrete ties, while twin stem iron shoulders are designed for Bi-Block or Twin Block concrete ties.
