Neenah Foundry

What Neenah Foundry does

Neenah Foundry Company is a U.S. cast iron foundry manufacturer founded in 1872, producing engineered infrastructure castings including manhole frames and covers, inlet and trench grates, airport drainage products, bridge drainage components, tree grates, detectable warning plates, downspout boots, and access hatch covers. The company also markets specialty security and safety products under the InfraLOCK and Controlled Pressure Release sub-brands, including a high-security locking manhole system and a pressure-release cover engineered to vent up to four inches during explosion events without leaving the frame. Manufacturing is anchored at two foundries in Neenah, Wisconsin and Medley (Miami), Florida, with a nationwide footprint complemented by 14 distribution centers and two general offices across the United States.

Since July 2022, Neenah Foundry has operated as a wholly owned subsidiary of Charlotte Pipe and Foundry Company, seated within Charlotte Pipe's Infrastructure Division alongside Deeter Foundry, U.S. Foundry, and (as of November 2025) Bingham & Taylor. In March 2026, the entities formally aligned operations under a unified commercial structure. The company sells primarily through a direct, quote-based inside sales motion targeting municipal governments, water and gas utilities, airport authorities, and infrastructure contractors, supported by field sales reps and customer service. Pricing is not publicly listed; transactions are negotiated via Inside Sales Representatives, with order status handled by Customer Service Representatives.

Customer acquisition is reinforced by industry-event participation (PWX, WEFTEC, AWWA ACE, Data Center World Power), a Lunch & Learn educational program aimed at municipal and utility specifiers, and a content library of case studies, brochures, tools, videos, and white papers. Distribution is direct-to-enterprise through Charlotte Pipe's Infrastructure Division channels and regional distribution centers. The company holds a documented conflict-minerals policy aligned with the IPC-1755 / CMRT standard for 3TG sourcing. Vik Bhatia has served as CEO of Neenah Enterprises, Inc. since May 4, 2023.
