Koppers

Our Rock Hill, SC team proudly served as a key sponsor of the Come-See-Me Festival, a 10-day community tradition celebrating the city’s gardens and local spirit.

Team members participated in the parade, ran in the 5K, sponsored a cooking competition, and served in festival leadership roles! 👏

Mark Karpinen's 18-year career at Koppers has been dedicated to producing the highest quality products for our customers, and ensuring that they can stand the test of time.

United for Infrastructure

Our Rock Hill team continues to inspire local students. 📚

Employees joined classrooms as guest readers during One Book One School and surprised students with lemonade and Koppers trinkets.

They also participated in Career Day, speaking with students about careers in science and lab environments and how materials like copper are used in our industry. 🧪
