Plastic Composite Sleeper
A Plastic Composite Sleeper is a type of railway sleeper made from a blend of plastic materials, are durable, lightweight, and resistant to environmental factors like moisture, chemicals, and UV rays. They require minimal maintenance, offer a longer lifespan than traditional wooden or concrete sleepers, and are an eco-friendly alternative, helping to reduce waste and promote sustainability in railway infrastructure. We GNEE rail are a trusted name in rail fastener manufacturing, producing rail clips, tie plates, concrete sleepers, composite sleepers, wooden sleepers, rail spikes, and fastening systems. Our composite sleepers, including HDPE, UHMWPE, FFU synthetic, and polyethylene varieties, guarantee quality, customization, and compliance with international norms.
