Stewart Iron Works

What Stewart Iron Works does

Stewart Iron Works is a privately held custom commercial metal fabricator and ornamental metalwork company founded in 1862 in Covington, Kentucky, now headquartered in Erlanger, KY and operating as a subsidiary of the Huseman Group following its 2019 acquisition. The company produces custom steel, aluminum, bronze, glass, and stainless steel metalwork including staircases, railings (pipe, tube, decorative metal, decorative glass), fences, gates, bollards, and site amenities under Division 5 (commercial/miscellaneous metals) and Division 32 (decorative fences and gates) CSI specifications, and provides specialized historic metalwork restoration and replication.

The company delivers projects through three flexible models: Design Build (full-service from bidding through installation), Fab+Ship (fabrication with nationwide shipping for self-arranged local installation), and Installation-only (installing decorative glass railing systems and utility metalwork produced by other manufacturers). Customers span six verticals — Government, Education, Public Works, Culture + Entertainment, Sports, and Commercial — and include named logos such as Vanderbilt University, the University of Cincinnati, the Kentucky Governor's Mansion, the Indianapolis Motor Speedway Museum, the Taft Museum of Art, the Mercantile Library, and multiple National Historic Landmarks. The company holds federal contracting credentials (UEI, CAGE/NCAGE, and five NAICS codes) enabling direct bidding on government work.

Revenue is generated on a project-based, quote-driven model with no public pricing and no recurring subscription or ARR mechanics; contract cadences range from one-time projects to multi-year engagements. Stewart differentiates through preserved hand-forging craftsmanship, deep NOMMA weld-finish expertise, multi-metal fabrication capability at scale, and 160+ years of brand heritage symbolized by the Stewart Shield trademark stamped on completed work. The current employee base is in the 11-50 range, materially smaller than the historical peak of 3,000+ during the post-WWII housing boom, reflecting a deliberate shift to a high-skill, lower-volume craft model.

Direct peers

• Robinson Iron: Alabama-based custom ornamental and architectural ironwork manufacturer with deep historic restoration capabilities, serving government, institutional, and commercial clients nationwide.

Directly comparable to Stewart's Division 5/32 metalwork portfolio, with overlapping customer base of architects, contractors, and OEMs.
