The deal brings nine Interstate locations and more than 150 employees into Curbell’s network, increasing its total footprint to 31 sites nationwide. Interstate Advanced Materials distributes plastic and composite materials across a range of end markets, including aerospace, medical, semiconductor and agriculture.

Curbell said the acquisition strengthens its ability to serve customers in key growth regions and enhances its portfolio of materials and value-added services. Interstate’s existing leadership and team will remain in place.

“Interstate is a strong strategic fit for Curbell,” added Gerry Helbig, President of Curbell Plastics. “This acquisition significantly increases our western U.S. presence, expands our reach in important markets and brings together two organizations with aligned values and a shared commitment to customer success.”

“Curbell is the right long-term owner for Interstate,” added Cole Klokkevold, CEO of Interstate Advanced Materials. “They share our values as a family-owned business and our commitment to taking care of customers and employees. I am confident our team and our customers are in good hands for the future.”

Strategically, the move reinforces ongoing consolidation in the plastics distribution sector, where scale, geographic density and technical capabilities are increasingly critical to serving diverse industrial and specialty end markets. The addition of Interstate also broadens Curbell’s customer mix and strengthens its position in industries requiring engineered materials and fabrication expertise.

Based in Orchard Park, NY, Curbell Plastics supplies plastic sheet, rod, tube and related materials to industrial, commercial and institutional customers nationwide.
