FFU is a glass fibre-reinforced foamed polyurethane material. FFU has a wood-like appearance, and although lightweight, it is extremely strong and corrosion-free.

FFU does not absorb water, features excellent electrical insulation, and high
chemical resistance.

FFU is widely applied across the world as high performance
railway sleepers.

FFU sleepers are easily installed, suitable for high-speed tracks, ecologically compatible and require very little maintenance.

FFU is the perfect durable alternative to natural wood by its superiority in life cycle cost analysis.
