Sustainable KLP® Hybrid Polymer SleepersKLP® Hybrid Polymer Sleepers are a sustainable and maintenance free alternative for wooden or concrete sleepers, turnout sleepers and bridge sleepers. The sleeper is manufactured from a high quality, ductile polymer with steel bars encased, which provides both high strength & high impact resistance properties as well as excellent damping characteristics. The expected lifespan of the sleepers is more than 50 years, thus representing a good investment with low Life Cycle Costs. KLP® Hybrid Polymer Sleepers furthermore contribute to substantial vibration and sound reduction. The German Federal Railway Authority (Eisenbahn-Bundesamt) has already approved the use of different types of KLP® Hybrid Polymer Sleepers for operational testing. Lankhorst has supplied hybrid polymer sleepers to several projects in The Netherlands, France, Austria, Germany, Switzerland, Malaysia and Sweden.
