What Enerfab does

Enerfab, LLC is a Cincinnati, Ohio-based privately held industrial contractor founded in 1901 and operated under parent HBH Holdings, Inc. The company provides a vertically integrated combination of fabrication, construction, and maintenance services to enterprise customers across heavy industrial end markets including power generation, chemical and refining, food and beverage, data centers, battery/EV manufacturing, hydrogen, mining, and water/wastewater. Service delivery spans 14 regional offices and approximately 985,000 square feet of fabrication capacity across the Midwest, Ohio Valley, Gulf Coast, and Eastern U.S., supported by 4,000+ employees and over 3,500 craftworkers.

The core product portfolio centers on ASME-certified process tanks, pressure vessels, modular skids, columns, towers, fermentation vessels, high-alloy corrosion-resistant equipment, heat exchangers, and piping systems, complemented by mechanical, electrical, structural, and refractory construction plus long-term integrated maintenance partnerships and shutdown/turnaround services. Technology differentiation comes from 1,500+ ASME-qualified weld procedures, 3D laser scanning with over 3 million data points, robotic and narrow-groove welding automation, an in-house Viewfab (VF) real-time project tracking portal, and a recently launched Rapid Response emergency fabrication service that compresses lead times from months to weeks. The company operates through affiliated brands Enerpipe (pipe fabrication), TMI Fabricators (structural steel), Brighton Tru-Edge (cold-formed heads), Triad Refractory Services (high-heat work), and the newly created Enerfab Modular (prefabricated multi-trade modules).

Revenue is generated primarily through project-based contracts — one-time fabrication and capital project work supplemented by recurring long-term maintenance partnerships — with go-to-market executed through direct enterprise field sales backed by strong national and local union labor relationships. The company reported FY2025 revenues exceeding $700 million, has roughly doubled in size over the past three years, and is positioning itself around three secular tailwinds: data center infrastructure build-out, energy transition (hydrogen, battery storage), and modular construction as a productivity lever in industrial project delivery.
