Railroad composite sleepers are highly resistant to environmental factors such as moisture, chemicals, and UV rays, offering a longer lifespan compared to traditional wooden or concrete sleepers. They are lightweight, low-maintenance, and eco-friendly, making them a cost-effective and sustainable solution for modern railway systems. We GNEE rail are dedicated to rail fastening systems, we manufacture products like rail clips, tie plates, and sleepers, including concrete, composite, and wooden varieties. Our composite sleeper options include HDPE, UHMWPE, FFU synthetic, and polyethylene, all customizable and adhering to global standards. Contact us for further details!
