Description

What is composite sleeper

Composite sleeper, also known as synthetic sleeper, is a type of railway sleeper made from continuous glass fiber-reinforced polyurethane foam material. It combines the characteristics of glass fiber-reinforced plastic composite and foam materials, offering advantages such as high strength, light weight, insulation, chemical resistance, and similarity to wood properties. Widely used in high-speed railways and subways, especially in situations where the use of concrete sleepers is limited.

Advantages of GNEE Composite Sleepers

● Strong support

Composite sleepers provide strong support, ensuring stability for railway tracks.

● Lightweight Design

Being lightweight makes handling, transportation, and installation more convenient.

● Insulation Properties

The material's insulation capabilities enhance safety by reducing electrical conductivity.

● Chemical Resistance

Composite sleepers resist chemicals, ensuring durability in various environmental conditions.

● Wood-Like Properties

Similar to wood, they allow for easy nailing and riveting during installation.

● Low Maintenance

Their durable nature translates to lower maintenance needs compared to traditional materials.
