Product Description
Rail shoulder, also known as rail iron shoulder, is a critical component cast into concrete ties to secure elastic rail clips. These components provide essential lateral support and ensure the stability of the rail tracks.
Depending on requirements, rail shoulders can be classified by shape into Single Stem or Twin Stems, and by manufacturing process into casting, weld-on, and hot forging types. Cast-in shoulders are embedded during the concrete casting process, while weld-on shoulders are used for specific rail fixations.
Quality Control System
As an ISO 9001 certified manufacturer, we adhere to a rigorous quality management system to ensure every rail shoulder meets international standards.
1
Raw Material Testing: Comprehensive inspection of chemical composition and mechanical properties before production begins.
2
Batch Inspection: Systematic sampling and batch testing during manufacturing with full material certification.
3
Rigorous Standards: Physical and chemical testing tailored to specific product requirements; materials are rejected if they do not meet strict criteria.
4
Technical Guidance: Regular coordination and technical guidance for all manufacturing stages to ensure qualified delivery.
Frequently Asked Questions (FAQ)
What is the primary function of a rail shoulder?
The rail shoulder is embedded in concrete ties to grip the elastic rail clip effectively and provide lateral support to the rail, ensuring track stability.
What are the different types of rail shoulders available?
There are two common types: Cast-in Shoulders and Weld-on Shoulders. Based on stems, they are categorized as Single Stem (for pre-stressed concrete ties) and Twin Stem (for Bi-Block or Twin Block ties).
How are rail shoulders manufactured?
They are produced using three main methods: casting, welding (weld-on), and hot forging.
Which quality standard do these products follow?
All products are manufactured in accordance with the ISO 9001 quality management system, covering raw materials to finished goods.
What material testing is performed?
We test for chemical composition, mechanical properties, and conduct physical/chemical inspections to ensure compliance with technical indicators.
What is the annual production capacity?
The facility has a production capacity of approximately 500,000 tons per year.
