Welcome to the new Koppers website.

Our Products

We are what the world is made of—we use renewable and repurposed raw materials to protect and extend the life of global infrastructure, for a more sustainable world.

Our products serve as the foundational elements of our global infrastructure.

Each and every day, our team works to create essential products and provide services that help move, connect, and safeguard people. What we do is mission-critical to protecting what matters in our world today and preserving our future for a better tomorrow.
Our belief in doing things the right way for the right reasons is what drives us to deliver high-value products and services to markets addressing global needs and infrastructure demands. We believe that by setting our bar high, others will follow.

Koppers business model is circular by nature, structured on the reuse of waste and scrap materials. The recycling of these materials drives our production of wood preservatives for railroad crossties, utility poles, and outdoor wooden structures, as well as the manufacturing of aluminum, steel, and other essential products used every day. This process of byproduct transformation is our signature, the foundation upon which our company was built and, without a doubt, a critical demonstration of our roots in sustainability.
