Welcome to the new Koppers website.

What We Do

We provide wood preservation technologies, carbon compounds, and services that support vital infrastructure around the world. But our actions, impact, and values dig much deeper than that.

We work every day to balance the products and services we provide, the environmental footprint they leave behind, and the interests of the communities we serve.

Supporting critical infrastructure around the globe means enhancing the stability and durability of the structures our world depends on. From railroad crossties, utility poles, outdoor wooden structures, and enhanced carbon products, to expert services spanning repair, maintenance, and recovery, we offer a fully integrated suite of products and services.
We also know the world depends on us to operate responsibly. It’s why sustainability and our Zero Harm commitment to safety serve as the foundation for everything we do. By owning our responsibility and staying resilient in the face of an ever-changing tomorrow, we further the critical role we play each day in the safe transport of goods, access to power and digital connectivity, and creation of extraordinary outdoor spaces for individuals and communities everywhere to enjoy.

Koppers Vertical Integration

Our vertically integrated business model keeps our segments closely interconnected, united by wood preservation technologies across diverse markets. With this model, we're not overly dependent on any one segment—instead our balanced portfolio allows for surety of certain raw materials, value-chain flexibility, and the ability to optimize our network.

Railroad

A global manufacturer of items essential to everyday life, our treated wood products help build and preserve critical railroad infrastructure for improved accessibility, streamlined operations, and efficient transportation of goods around the globe.

Services under this segment include expert engineering, design, repair, and rehabilitation services for railroad bridge repair and replacement. Our recovery services also provide the railroad industry with integrated, environmentally friendly wood waste disposal solutions.

Utility

Backed by our sustainability-first strategy and guided by unmatched industry expertise across the entire lifecycle, our utility products and services cover quality wood poles, cross arms, piling, and more. And as the largest utility pole manufacturer in the U.S., our customers include investor-owned groups, cooperatives, and municipal utility companies.

Our Utility Services team maintains poles, and our Recovery Solutions offer disposal options for materials at the end of their lifecycle, allowing us to serve customers at every stage in every aspect.
