Description

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.

Comparation of railway sleepers

Feature Composite Railway Sleepers Concrete Railway Sleepers Wooden Railway Sleepers
Strength High, good flexibility Very high Non-uniform, decreases over time
Durability Long-term stability for many years Short lifespan Lifespan of 10-15 years
Construction Easy to construct, can be processed on-site, short construction period Difficult to construct, cannot be processed on-site, long construction period Favorable for transportation and construction, short construction period
Repair and Refurbishment Easy, can adapt to changes in track position Difficult, challenging to adjust track position Difficult to repair and refurbish, single-use
Production Efficiency High, stable quality, short delivery time Low, many molds, long delivery time Long delivery time
Environmental Protection Recyclable Difficult to recycle Depletes forest resources
Cost-effectiveness Reduces overall costs Increases construction costs, high cost Increases replacement frequency and maintenance costs
Overall Evaluation Suitable for high-performance new materials for railway sleepers Heavyweight, short lifespan No longer in use, depletes forest resources
