The Gund Company

What The Gund Company does

The Gund Company is a fourth-generation, family-owned manufacturer and fabricator of engineered material solutions headquartered in St. Louis, Missouri, founded in 1951. The company produces a broad portfolio of thermoset rigid composites (including NEMA grades G-10, G-11, FR4, GPO-1, GPO-3 and proprietary formulations), thermoplastic materials (PolyPro FR, polycarbonate, high-performance polymers such as PTFE, PPS, PEEK, PEI, PAI), flexible insulation materials (G-Flex, RotoGuard, G-Flex APA), elastomeric compounds, aramid and cellulose-based papers, magnetic wedge materials (MagNohl), and Resistance Temperature Detectors. Manufacturing is vertically integrated from resin formulation through VARTM composite processing, die-cutting, stamping, precision punching, slitting, assembly, and kitting, supported by application engineering and a comparative materials testing lab.

The company's products serve electrical insulation and composite-material use cases across switchgear, power electronics, generators, motors, transformers, oil and gas (frac plugs and balls), aerospace, electric vehicles, metals processing, and medical device end markets. Revenue is generated through custom hardware sales priced via quote-based request forms for gaskets, O-rings, wedges, pole collars, RTDs, PolyLiner FR, and general material requests, with multi-year contracts and customer inventory programs. Distribution is direct through enterprise field sales supported by technical webinars, a technical resource library, and comparative material data sheets. Quality credentials include ISO 9001:2015, AS9100D, Nadcap, ITAR, REACH, and RoHS, with ISO 14001 held through IDI Fabrication.

Through a sequenced buy-and-build strategy, The Gund Company acquired IDI Fabrication in July 2025 (Illinois, Indiana, Monterrey), the Von Roll Industrial Composites Business in September 2025 (Augsburg, Germany; Bradford, UK), and ABC Insulation Supply in March 2026 (Memphis, TN), scaling the footprint to 17 manufacturing locations across 7 countries and an employee base of more than 800, of which 30% is employee-owned. Leadership comprises CEO Steve Gund, President Brian Krupich, EVP of Business Growth Mike Moran, and EVP of Operations Nels Ostrom.
