Welcoming GPI Composites to the Zynik Family
At Zynik, our growth is guided by a simple belief: businesses endure when they are built around skilled people, long-term thinking, and a deep commitment to customers.
We are proud to welcome GPI Composites of Schofield, Wisconsin to the Zynik family of companies. GPI joins our Engineered Systems platform within the RPS Industrial Group, strengthening our corrosion-resistant composite manufacturing capabilities across North America.
Founded in 1973, GPI has spent more than five decades designing and manufacturing fiberglass-reinforced plastic (FRP) tanks, vessels, scrubbers, piping systems, and custom composite equipment for industrial environments where corrosion resistance and reliability are essential.
GPI’s reputation was earned through consistency, technical depth, and long-standing customer relationships in industries such as chemical processing, wastewater treatment, mining, pulp and paper, and other demanding sectors.
This partnership reflects more than an expansion of capability. It reflects alignment in values.
