Railway sleepers, also called railroad ties, railway crossties, or railway ties, are important railway components of the rail industry. Generally, the rail sleeper is always laying between two rail tracks to keep the correct space of the gauge.
Synthetic sleeper, also known as a railway composite sleeper, made of a composite material sheet produced by a foam extrusion process with continuous glass fiber as a reinforcing material(Fiber-reinforced Foamed Urethane), polyurethane as a matrix material, supplemented with additives. It has higher strength and widely used as a structural material, besides, it is light in weight, insulating and resistant to aging, heat-insulating, chemical-resistant.

Through years of successful testing in heavy-haul, mainline and public transport operations, the composite sleeper has proven to be an innovative, reliable and environmentally friendly alternative. All verifications, tests and operational trials required for approval have been carried out successfully. Thus, our future-oriented product extension meets the same safety and quality standards as all other products we have been offering our customers for decades.

In complete contrast to the conventional wooden sleeper, the composite sleeper is not only more climate-friendly, because toxic impregnating agents do not have to added, but also resistant in the most challenging climatic regions. Whether constant humidity and ideal conditions for fungal attack or freezing cold in Siberia, the quality of the product remains unchanged.

The composite sleeper is a railway sleeper made of a new material called continuous glass fiber reinforced polyurethane foam. Concrete sleepers have been popularized in countries around the world, but lack of flexibility is also a serious drawback. Although the wooden sleepers are flexible, the total amount of forest resources in the world has decreased sharply in recent years. In addition, the wooden sleeper is easy to be corroded. If it is treated with anticorrosion, it will cause certain influence on the environment. For these reasons, the era of heavy use of wooden sleeper has become a thing of the past. Due to the use of new materials, the composite sleepers not only inherit the advantages of the two types of railway sleepers, but also avoids their drawbacks. Our composite sleepers are more and more popular in the world, and have been exported to the United States, India, Chile and other countries.
