🛠️ 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 is used to grip the clip effectively and provides lateral support to the rail. The rail shoulder 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 the Single Stem Iron Shoulder used in pre-stressed concrete ties, and the other is the 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 systems. From supplier quality control to finished products, standard procedures are strictly followed.
1
Pre-production Inspection: Before producing Rail Shoulders, raw materials are checked and tested. Suppliers must provide production batch numbers, chemical composition, mechanical properties, and other indicators.
2
Batch Testing: Quality control inspectors perform sample sampling and batch testing after the manufacturing process, providing material certificates to control the testing process.
3
Physical & Chemical Testing: Corresponding tests are conducted based on specific requirements. Materials that do not meet strict standards are rejected.
4
Technical Guidance: Regular quality coordination meetings and technical guidance are provided to ensure that qualified products are delivered to customers.
❓ Frequently Asked Questions
What are the primary functions of a rail shoulder?
A rail shoulder is primarily used to be cast into concrete ties to fixate elastic rail clips and provide essential lateral support to the rail.
How are rail shoulders classified by shape?
They are generally classified into Single Stem Rail Iron Shoulders and Twin Stems Rail Iron Shoulders, depending on the type of concrete tie used.
What manufacturing methods are used for these shoulders?
Rail shoulders are manufactured through three main methods: casting, welding (weld-on), and hot forging.
Which type of shoulder is used for Bi-Block concrete ties?
The Twin Stem Iron Shoulder is specifically designed for use in Bi-Block or Twin Block concrete ties.
How do you ensure the quality of the raw materials?
We require suppliers to provide chemical composition and mechanical property indicators, and we perform independent physical and chemical testing before production begins.
Are the products certified for international standards?
Yes, the production process follows ISO 9001/2008 standards to ensure consistent high quality and safety in rail infrastructure.
