Fibre-reinforced foam urethane (FFU) sleepers for switches, crossings, and special trackwork applications. FFU combines the machinability of timber with the durability of synthetic materials, enabling complex geometries for turnouts and S&C layouts that recycled plastic sleepers cannot achieve.
Glass fibre-reinforced polyurethane foam (FFU)
Approximately 700–750 kg/m³
Comparable to high-grade tropical hardwood
Less than 1% by weight
-40°C to +60°C continuous
All standard screw-spike and clip systems
Industries and operations where this product is used.
Railway sleepers (ties) are the foundation of rail track structure, distributing loads from rails to the ballast bed. Lankhorst Engineered Products manufactures recycled plastic railway sleepers that deliver a 50+ year maintenance-free service life — dramatically outperforming timber in durability, environmental impact, and total cost of ownership.
