ACI Building Systems

What ACI Building Systems does

ACI Building Systems, LLC is a privately held US manufacturer of engineered metal building systems founded in 1990 by Bill Watkins and headquartered in Batesville, Mississippi. The company operates from a 270,000 sq. ft. manufacturing facility on 125 acres, with technical offices in five US states, producing custom steel structural frames (rigid frame clear span, flush wall, modular, tapered beam, single slope), cold-formed steel members (G-90 angles, zees, cees, eave struts, hat channels), wall and roof panels (PBM, PBR, SnapLok, StratoShield, Superior Rib, UltraLok, FW-120), standing seam roofing systems, and roof-transformation retrofit services. ACI holds the IAS AC 472 accreditation (the IBC Chapter 17 benchmark for engineered metal building manufacturers), MBMA membership, and UL, FM Global, and TDI certifications.

The business is organized into a Building Division and a Roofing Division, with a sub-brand, Accelerated Building Systems (launched September 2021), delivering weld-free, cold-formed, bolt-and-screw steel buildings with 5-day engineering plans and as little as 3-week materials delivery for small-span applications. ACI serves commercial, industrial, mini-storage/self-storage, community, architectural, and roofing customers — including named enterprise and government projects such as The Pavilion at Ole Miss (225,000 sq. ft.), West Pier at the Port of Gulfport (Chiquita ripening facility), Ford Ice Center, Auburn University, and Huntsville Fire Station #20. Across 33+ years the company has delivered more than 20,000 steel buildings to 2,400+ customers across the United States.

ACI generates revenue primarily through one-time, project-based sales of engineered steel buildings, components, and roofing systems via direct enterprise field sales with district sales managers, a separate sales force for the Accelerated Buildings sub-brand supported by an online design tool, and turn-key pricing for mini-storage projects delivered through a qualified contractor network. Pricing is custom quote-based; the company does not publish list pricing. The customer mix spans SMBs, enterprise accounts, government, and educational institutions across the United States, with revenue concentrated in commercial, industrial, and mini-storage use cases.
