Robroy Industries

What Robroy Industries does

Robroy Industries is a fourth-generation family-owned industrial manufacturer founded in 1905 and headquartered in Verona, Pennsylvania, operating two business divisions across facilities in Pennsylvania, Michigan, and Texas. The Enclosures Division (Belding, Michigan) produces non-metallic electrical enclosures under the Stahlin and AttaBox brands, including fiberglass, polycarbonate, and PVC enclosures rated NEMA 4X, NEMA 6P, and IEC IP66/IP68/IP69, with proprietary technologies such as SolarGuard UV protection and the patent-pending SpeedPanel and P5SA systems. The Raceway Division (Gilmer and Avinger, Texas) manufactures PVC-coated conduit and fittings under the Plasti-Bond brand (ISO 9001 certified, first in industry to receive ETL certification for aluminum conduit coating performance), stainless steel raceway (Robroy Stainless Steel, ROCKET RACK), and non-coated raceway (ECN/Korns) for use in corrosive and hazardous-location environments.

The company generates revenue primarily through B2B hardware sales of these enclosures, conduit, fittings, and accessories, distributed via a national sales representative network, distributors, and brand-specific websites. Customers span industrial manufacturing, electrical construction, telecommunications, HVAC, government/municipal, oil and gas, and solar/renewable energy verticals, with no public anchor customer concentration. Robroy monetizes adjacent value through its Corrosion College training program (specification lock-in) and, since the 2021 acquisition of Ideal Integrations, electrical integration services. Go-to-market combines enterprise field sales with channel partners and event-driven demand generation at major industry trade shows; pricing is not publicly disclosed. The company has expanded its product surface through recent launches including Plasti-Bond ETL-certified aluminum conduit (2026), the Stahlin SpeedPanel (2025-2026), and the SolarShield HMI Cover expansion (2025), and has been recognized in EC&M 2026 Product of the Year and Control Engineering/Plant Engineering 2025 Silver awards. Robroy Industries, Inc. is a privately held Pennsylvania corporation with no external parent, private equity, or venture capital ownership.
