Welcome to the new Koppers website.


We are the largest provider of pressure-treated railroad crossties for Class I railroads in North America.

Our products ensure the safe, reliable movement of people and goods by rail.

Our wood treatment products not only help extend the lifespan of crossties by up to 40 years—they also help reduce deforestation, preserve natural carbon stores, and increase the overall reliability of wood products across various industries. Our product roster also includes bonded rail joints and track components for freight, transit, high-speed, and heavy haul needs. And, we offer railroad services, including engineering, design, repair, and inspection of railroad bridges within our North American Class I customer base.
