Cast-in Rail Shoulders: These are prefabricated pieces in concrete sleepers, either single or double, used to secure elastic rails within a fastening system, mainly electronic fastenings. Pre-embedded in concrete sleepers, they work together with elastic clips to fix the rails securely.
Weld-on Shoulders: Designed for special trackwork locations where standard tie plates cannot be used. Applications include switches, scales, steel structures, and maintenance facilities. Beveled for easy welding, they provide optimum lateral resistance and maximum clip-toe load for all standard rail sizes.

The two main types are Cast-in shoulders, which are pre-embedded in concrete sleepers, and Weld-on shoulders, which are used in special trackwork locations.
They are designed to fit various standards including 115RE, 136RE, UIC54, UIC60, 54E1, and 60E1.
Common materials include ductile cast iron grades such as QT500-7, QT450-10, and QT400-15, ensuring high tensile strength and durability.
Weld-on shoulders are ideal for switches, scales, steel structures, and maintenance facilities where standard tie plates are not applicable.
The production capacity is approximately 500,000 pieces per month to meet large-scale railway project demands.
Yes, the rail shoulders can be customized in terms of color and specific dimensions to meet individual railway project requirements.
