Looking for strong & resilient rail road sleepers? KLP® Polymer Sleepers are a sustainable solution!

Polymer sleepers for your railroad track

Are you wondering how KLP® Hybrid Polymer Sleepers can make your railroad more sustainable, and allow you to reduce Rail Sleeper Life Cycle Management Costs? The KLP® Hybrid Polymer Sleepers, produced from recycled plastics, offers excellent damping properties, as well as optimum bending stiffness. Moreover, the KLP® Hybrid Polymer Sleeper has low thermal expansion thanks to its combination of polymer and steel rod inserts. Furthermore, the KLP® Hybrid Polymer Sleepers will keep these properties during its expected service life of over 50 years. 

The KLP® Hybrid Polymer Sleepers offer outstanding service in a range of rail applications, including:


Polymer sleepers with high bending stiffness & low thermal expansion 

The sustainable KLP® Hybrid Polymer Sleeper is manufactured from a high quality, ductile plastic with encased steel reinforcement bars, providing both high strength properties and low thermal expansion. The polymer railroad sleeper’s excellent damping characteristics contribute to substantial vibration and sound reduction.


Polymer Sleepers with Low Life Cycle Costs

The KLP® Hybrid Polymer Sleeper is virtually maintenance free. With an expected service life of more than 50 years and low Life Cycle Costs, KLP® is an outstanding investment compared to timber sleepers where the lifespan of untreated oak sleepers is limited to roughly 8-12 years.


Polymer sleepers & sustainability

Lankhorst KLP® Hybrid Polymer Sleepers were first introduced in early 2006. The ban on creosote and restricted availability of hardwood were the main drivers for Lankhorst to develop a polymer sleeper manufactured from 100% recycled plastics as a sustainable and maintenance free alternative to timber sleepers. Since their introduction, Lankhorst has supplied Hybrid Polymer Sleepers to several rail operators in Europe, North America, South-East Asia, Australia and New Zealand region.
