Composite railway sleepers
Composite railway sleepers, also known as composite railroad ties. It ia a kind of lightweight and corrosion-resistant material made by reinforcing rigid polyurethane foam with glass long fibers. And offering many advantages of high strength, shock absorption, noise reduction, electrical insulation, durability, and environmental friendliness.
GNEE Rail is a trusted and professional manufacturer of railway sleepers, having 20 years of reliable experience. Our research and production base spans 10,000 square meters, dedicated to developing and manufacturing comprehensive solutions for railway track materials in the field of railway transportation.
The composite sleeper that GNEE rail manufactured offer environmentally friendliness, excellent fatigue resistance, long lifespan, and high cost-effectiveness. They serve as alternatives to wooden sleeper and concrete sleeper, and suitable for various applications including urban rail transit, conventional railways, heavy-duty railways, high-speed rail lines, vehicle depots, turnouts, bridges, and other railway sections.
