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.
