Durable Composite Railway Synthetic Sleeper For Railway Tracks

Railway Synthetic Sleeper

A Railway Synthetic Sleeper is a type of railway sleeper made from synthetic materials, such as polymer composites or recycled plastics. These sleepers are highly durable, resistant to environmental factors like moisture, chemicals, and wear, and offer a longer lifespan compared to traditional wood or concrete sleepers. We GNEE rail specialize in the production of high-quality rail fasteners, including rail clips, tie plates, sleepers (concrete, composite, and wooden), rail spikes, and complete fastening systems. Our composite sleepers-crafted from HDPE, UHMWPE, FFU synthetic, and polyethylene-are designed to meet international standards and can be tailored to your needs. Reach out anytime!
