What Panel Built, Inc. does

Panel Built, Inc. is a privately held U.S. manufacturer of custom prefabricated modular buildings founded in 1995 by brothers Pat and Mike Kiernan and headquartered in Blairsville, Georgia. The company designs, engineers, and fabricates a broad portfolio of modular structures — including modular offices, structural steel mezzanines, security and ballistic-rated booths, cleanrooms, electrical houses (e-houses), control rooms, SCIF rooms, blast-resistant structures, towers, transit shelters, and barrier rails — in controlled offsite environments using 3-inch composite sandwich wall panels and a proprietary binder-post wall system that enables customization, vertical chases for electrical/data, and load-bearing multi-story configurations. Production is centered at the company's Blairsville campus, which is undergoing a 73,000 sq ft main expansion and a 6,400 sq ft expansion at a secondary facility to support growing electric utility demand.

The company operates a project-based, quote-priced business model: every building is custom-engineered to buyer specifications, with revenue recognized primarily on one-time project sales plus optional installation services. Its go-to-market is direct sales-led, leveraging a dedicated sales team, regional sales representatives, a "Request a Quote" channel on its website, and GSA contract status (GS-07-0168X) for federal and military procurement. Customers are diversified across industrial/manufacturing, government/military, utilities and energy, warehousing/distribution, data centers, healthcare/pharmaceuticals, commercial/institutional, transportation/public safety, and arts/culture verticals, with named engagements including Robins Air Force Base, Reynolds Business Systems, Boat Top Manufacturing, and Executive Coach Builders.

Panel Built's strategic posture is anchored on three pillars: (1) customizability at scale, supported by engineering depth and the binder-post modular wall architecture; (2) speed, with the company claiming fastest lead times in the industry and offering 3D video proposals during the sales phase; and (3) regulatory and code credibility (GSA, OSHA, IBC, BOCA, UBC compliance). Recent moves include an expanded strategic partnership with Schweitzer Engineering Laboratories (SEL) to address large-scale power and utility infrastructure projects, product extensions into data center infrastructure and art storage facilities, and a 2025 "Best of Georgia" recognition in steel products manufacturing from the Georgia Business Journal.
