Composite Railroad Sleeper
Composite Railroad Sleepers are modern sleepers made from advanced composite materials such as plastic, fiberglass, or polymer blends. They are highly durable, resistant to moisture, chemicals, and UV rays, and offer a longer lifespan compared to traditional wood or concrete sleepers. Lightweight, low-maintenance, and eco-friendly, composite railroad sleepers provide a sustainable and cost-effective solution for contemporary railway systems. GNEE Rail, we specialize in top-quality railway products such as reinforced concrete sleepers, switch sleepers, bridge sleepers, rail fasteners, rail clips, tie plates, rail spikes, and complete fastening systems. Our composite sleepers, made from materials like HDPE, UHMWPE, FFU synthetic, and polyethylene, comply with international standards and can be customized to meet your specific needs. Trusted by clients in 30+ countries, we are here to serve you. Get in touch with us today!
