Railway Rail Cast Iron Shoulder Used on Concrete Sleeper

Rail shoulder, also called rail iron shoulder, is primarily used for casting into concrete ties to fixate elastic rail clips. These components provide critical lateral support to the rail and ensure the clips grip effectively. Depending on structural requirements, they are categorized into Single Stem and Twin Stems designs.

Manufacturing methods include casting, weld-on applications, and hot forging. The shoulder is semi-embedded during the tie casting process, forming a durable anchor point for rail fastening systems. Common variations include Cast-in Shoulders and Weld-on Shoulders, suitable for both pre-stressed concrete ties and bi-block/twin-block concrete ties.

Operating under a certified ISO 9001 management system, the production process follows strict standards from raw materials to finished rail shoulders.
