The best lateral and vertical stability amongst composite-type sleepers

Designed for longevity, not only to reduce the Total Cost of Ownership, but also to maintain continuous track stiffness.

  • For axle loads up to 25 tons
  • Customizable for 3rd rail track configurations
  • Bfl-s1 fire and smoke classification (EN13501-1)

Composite polymer sleepers for track

Manufactured from high quality, ductile polymer with steel bars encased. This provides high strength properties, low thermal expansion and excellent damping characteristics.
