A new type of environmentally friendly FFU composite sleeper for railway sleeper system with high strength, high durability, low linear coefficient of thermal expansion and low thermal conductivity.
Advantage of Composite Sleeper
1) Excellent durability, no water absorption, corrosion resistance, can maintain the strength and dimensional accuracy during construction for a long time;
2) Light weight, good construction performance, similar to the weight of wood (specific gravity is 0.74), easy to process on site;
3) High connection strength, high pull-out strength of spikes and screws, high retention rate when repeatedly nailed, and almost no reduction in strength due to oil stains;
4) Good electrical insulation, no water absorption, so it will not reduce insulation;
5) Can correspond to various processing, can be processed in the same way as wood (grooving, drilling, grinding, nailing, painting, bonding, etc.);
6) Good for environmental protection, because it replaces wood, it can protect forests, has a long life, can reduce waste gas, and some old materials can be recycled by relying on unique processing technology and bolting method.
