Ace Iron & Steel Corp

What Ace Iron & Steel Corp does

Ace Iron & Steel Corp is a Milwaukee, Wisconsin-based structural steel fabricator and erector founded in 1936 and operated under Jackson family ownership across multiple generations. The company produces engineered structural steel packages for commercial, healthcare, higher education, K-12, transportation, and entertainment-venue construction projects in the Upper Midwest, with a documented portfolio that includes the American Family Insurance Amphitheater Roof Raise, inpatient hospital work, Marquette and Moraine Park campus buildings, Cedarburg schools, Wisconsin DOT infrastructure, and the Ashwaubomay bridge.

Operations are anchored by a 22,400 sq. ft. manufacturing facility and a workforce in the 11-50 employee range, with capabilities spanning detailing, plate and shape processing (including a Messer EdgeMax plasma cutting table), fabrication, and field erection. The company holds AISC certification and earned a 2023 AISC IDEAS² Merit Award, signaling compliance with the quality standards required to bid on owner-specified certified structural steel scopes.

The business operates on a project-based, bid-driven revenue model typical of trade contracting: general contractors and public owners solicit pricing on engineered steel packages, Ace fabricates to approved shop drawings, and revenue is recognized on a percentage-of-completion or milestone basis tied to fabrication and erection progress. Pricing is driven by steel tonnage, connection complexity, and erection logistics rather than SaaS-style recurring contracts, which makes revenue inherently lumpy and tied to the Wisconsin non-residential construction cycle.

Broad incumbents

• Nucor Corporation: Largest U.S. steel producer and through its Vulcraft/Verco divisions a major structural steel joist and deck supplier — competes indirectly with Ace as both a steel input source and on selected fabricated structural components in the broader supply chain.
• Schuff Steel (DBM Global): National structural steel fabricator and erector (DBM Global subsidiary) operating across commercial, industrial, and infrastructure markets — a much larger competitor that competes with regional fabricators like Ace on larger institutional bids.
