KLP® Mainline Sleeper

KLP® Hybrid Polymer Sleepers:
High-quality ductile polymer, reinforced with steel. Strong, stable, sustainable, recyclable.

Benefits and Features

Optimised shape: Uses up to 30% less polymer, reduced costs, ease of handling. The profiled footing offers increased lateral stability in track, profiled side walls enable solid embedment in ballast which increases the resistance against upliftment.

Stability in-track: Profiled footing and steel reinforcement provide best lateral, longitudinal and gauge stability of poylmer-based sleepers, engineered to provide required track stiffness (valuable with interspersed replacement maintenance).

Diverse application: An excellent alternative to timber, concrete, steel and polymer sleepers.

Low life-cycle cost: 50 years design life, nearly maintenance free.

Easy to install: Use same tools as for timber to machine and install, compatible with most fastening systems, no fibre content (no respiratory equipment required).

Durable and sustainable: Steel provides required strength, polymer absorbs impact and noise, excellent chemical resistance, electrically insulated, no rot or splintering, moisture and fungus resistant, excellent UV resistance.

Environmentally friendly: Made from 100% recycled polymers, no toxic content, CO2 store, can be 100% recycled

Sleeper Construction

Two steel rebars: The backbone, offers required strength and bending stiffness, contains thermal expansion to that comparable of concrete and steel

High-quality ductile polymer: Encapsulates the steel bars, dampens impact, vibration and noise.
