Composite railroad ties also known as fiber-reinforced foamed urethane synthetic sleepers, fiberglass reinforced synthetic ties, polyurethane composite ties. Composite railroad ties are made from rigid polyurethane reinforced with continuous glass fiber. this combination provides high insulation and resistance to corrosion, protecting against chemical and biological damage. These ties resemble wooden sleepers but offer the combined benefits of wood and plastic sleepers, such as durability, low maintenance, and excellent performance. they are strong, lightweight, and resistant to environmental wear, making them ideal for various rail applications.
As leading supplier in composite railway sleeper manufacturing, we provide a range of products including HDPE, UHMWPE, FFU synthetic, and polyethylene sleepers. Our products are designed for customization and are widely used in rail systems, from switches and turnouts to bridges and viaducts. Highly regarded by customers globally, our sleepers are exported to North America, Europe, Southeast Asia, and more. Contact us today for innovative and durable railway solutions!
Lightweight and High Strength
Offers excellent insulation and corrosion resistance.
Improved Durability
Low water absorption, better electrical insulation, and resistance to UV aging, oil, heat, and fire.
Long-Lasting Performance
Maintains strength and dimensional accuracy over time.
Easy Field Processing
Easier to process (fluting, drilling, nailing, etc.) compared to wood.
High Pull-Out Strength
Strong spike and screw pull-out resistance, ideal for new or repaired sleepers.
Excellent Fatigue Resistance
High durability and antifatigue ability.
