A Composite Railway Tie is a type of railway tie (or sleeper) made from composite materials such as plastic, fiberglass, or a mixture of synthetic resins and fibers. These ties are designed to offer enhanced durability, resistance to environmental factors, and a longer lifespan compared to traditional wood or concrete ties. GNEE rail is as experts in rail fasteners, we provide a broad selection of products, from rail clips and tie plates to concrete and composite sleepers, wooden sleepers, rail spikes, and fastening systems. Our composite sleepers, made from HDPE, UHMWPE, FFU synthetic, and polyethylene, are customizable and globally certified. Feel free to connect with us!
