Railroad Composite Sleeper

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.
