Industry knowledge

The SKL clip rail fastening system is widely used for both ballasted tracks and concrete sleepers. Known for its reliable operation, minimal wear, and low maintenance requirements, the SKL system provides a high-elasticity solution for conventional and heavy-load railways due to its high toe load, dynamic fatigue strength, and resistance to rail creep.
