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!
Advantages of composite railroad ties
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.
