Durable Composite Sleepers Rail Fasteners For Railway Turnouts Crossings

Composite sleepers railway for turnouts & crossings

Composite sleepers are ideal for ballasted railroad tracks, for example in the application of turnouts and crossings. The elasticity of the plastic provides good damping and reduces wear. Steel bars completely encased within the KLP® Hybrid Polymer Switch & Crossing Sleeper reinforce the railroad sleeper and optimize its stiffness. These composite sleepers have the same damping characteristics as timber sleepers, which makes them suitable for 1:1 replacement of wood. An untreated oak sleeper has a life span of roughly 10 years. The expected life span of the maintenance free KLP® Hybrid Plastic Sleepers is more than 50 years, which makes these composite sleepers a good investment with low Life Cycle Costs.

The installation on site is simple, and the maintenance and repair works are greatly reduced.

It can keep the distance between the rail and the guard rail, the sleeper and the guard and the geometry of the line well, and the line condition is excellent and basically unchanged.

The sleeper surface is not easily peeled off.

Sizes available: sleeper height not less than 140mm, width not less than 200mm, and length upon customer need.

Product quality standard: CJ/T399-2012
