[Features]
  • [Excellent in durability]
    The synthetic sleepers are free from water absorption and corrosion, and capable of maintaining the strength and dimensional accuracy in the initial installation.
  • [Excellent in mechanical strength]
    The plastic foamed body(hard urethane resin)is reinforced by long glass fibers.
  • [Excellent in tightening strength]
    The pull-out strength of dog spikes and screw spikes is large, and the holding ratio is high during the cyclic driving. The strength is least degraded when oil is adhered thereto.
  • [Excellent in electric insulation]
    Since the synthetic sleeper absorbs no water, its electric insulation is not degraded.
  • [Ready for various machining works]
    Similar machining works(grooving, drilling, grinding, spike-driving, adhesion, and coating)to those of natural wood sleepers are available.
  • [A product friendly to the environment]
    Woods and forests are protected through the replacement from natural wood, and wastes are reduced in quantity due to the long service life.
