What SEKISUI FFU Railway Technology does
SEKISUI FFU Railway Technology is a business unit of Tokyo-listed SEKISUI CHEMICAL CO., LTD., specializing in the manufacture and global sale of FFU (Fibre Reinforced Form Urethane) synthetic railway sleepers. Founded on proprietary material science first installed in 1980, the company positions FFU as a long-life alternative to timber sleepers, with a documented service life exceeding 50 years versus 10–25 years for natural wood and identical machinability and density (740 kg/m³). The product portfolio includes FFU Synthetic Railway Sleepers (for bridges, switches, level crossings, and special applications), Calmmoon Rail (a rail-web noise shielding system achieving 3 dB noise reduction), FFU Passageways, FFU Slim Ties, and FFU Longitudinal Beams. Since 1980, over 3 million FFU sleepers have been installed across more than 2,000 km of track in over 35 countries.
The company serves railway infrastructure operators including Deutsche Bahn, Network Rail, JR East, JR Central, JR West, ÖBB, Banedanmark, ProRail, Wiener Linien, Renfe, KiwiRail, Metro Transit, and MRT Malaysia. Revenue is generated through project-based hardware sales, with quotations tailored to customer specifications and procurement conducted via enterprise infrastructure tenders. Manufacturing is performed at the original mother plant in Shiga-Ritto, Japan and a second plant in Roermond, Netherlands opened in 2022 to serve European demand, with the European headquarters in Düsseldorf under SEKISUI Chemical GmbH. Distribution is supplemented by regional partners including Delkor Rail (Australia), StarTrack (India), voestalpine Railway Systems Nortrak (North America), ACOSTA INGENIEROS (Spain), and AVG/Arneo (Germany). The business holds general EBA approval in Germany as the only synthetic sleeper manufacturer with this comprehensive certification, plus ADIF full acceptance in Spain and Network Rail full acceptance in the UK, and maintains EcoVadis Gold Medal, DJSI World Index, and S&P Global Sustainability Yearbook credentials.

SEKISUI FFU Railway Technology product offering
Product offeringCore offering
SEKISUI FFU Railway Technology manufactures and sells FFU (Fiber Reinforced Form Urethane) synthetic railway sleepers as long-lasting replacements for timber sleepers in railway superstructures, including applications for bridges, switches, flat sleepers, and special solutions. The company also produces and sells the Calmmoon Rail rail web noise shielding system, which reduces rail noise by an average of 3 dB. Products are sold directly to railway infrastructure operators, government-owned railway companies, metro operators, and port/industrial rail operators globally.
Product overview
SEKISUI FFU Railway Technology offers a portfolio of synthetic railway infrastructure products centered on FFU (Fibre Reinforced Form Urethane) technology. The core offering consists of FFU Synthetic Railway Sleepers, which serve as long-lasting alternatives to traditional timber sleepers with over 50 years service life. Complementing this is Calmmoon Rail, a rail web noise shielding system that achieves 3 dB noise reduction. The product line extends to specialized variants including FFU Passageways for worker walkways, FFU Slim Ties for space-constrained applications, and FFU Longitudinal Beams for bridge constructions. These products are distributed globally with manufacturing in Japan and Germany, serving railway operators across Europe, Asia-Pacific, and other regions.

Products and services
- FFU Synthetic Railway Sleeper FFU (Fibre Reinforced Form Urethane) synthetic railway sleepers are engineered wood-like products used as permanent replacements for timber sleepers in railway superstructures. They offer over 50 years of durability, identical weight to natural lumber (specific gravity ~740 kg/m³), machinability on-site with standard wood-working tools, electrical insulation, and resistance to rot, insect attack, and chemical corrosion. Applications include bridges, switches, flat sleepers, and special solutions. Target customers are railway infrastructure operators, government-owned railways, metro operators, and port/industrial rail operators.
- Calmmoon Rail Calmmoon Rail is a rail web noise shielding system designed to reduce railway noise by an average of 3 dB. It consists of a triangular-shaped thin steel plate combined with FFU material that covers the rail web to damp vibrations and shield noise. Installed on bridges and ballasted track for railway infrastructure operators in noise-sensitive areas, including a 40 km stretch in the Rhine Valley for Deutsche Bahn.
- FFU Passageway FFU passageway products are walkways installed across railway tracks to provide safe passage for train drivers and maintenance workers. They offer durability and long product life compared to timber alternatives. Used by railway infrastructure operators in track-side applications.
- FFU Slim Ties FFU slim ties are flat sleepers with reduced cross-sectional dimensions (e.g., 12x24cm, 12x26cm) designed for applications with limited ballast depth such as bridges and tunnels. Used by railway infrastructure operators in space-constrained installations.
- FFU Longitudinal Beams/Bearers FFU longitudinal beams (also called longitudinal baulks or bearers) are structural components used in bridge applications, providing support along the rail direction rather than traditional cross-wise sleepers. The longest-ever FFU synthetic bearers (16m × 710mm × 350mm) were produced for Network Rail's Newark flat crossing. Used by railway infrastructure operators for open-deck bridges and level crossings.
Quantifiable outcome
- 3 million+ FFU sleepers installed across 2,000+ km of track in 35+ countries since 1980
