LeJeune Steel Company

What LeJeune Steel Company does

LeJeune Steel Company is a privately held structural steel fabricator headquartered in Minneapolis, MN. Founded in 1944 as a playground equipment builder and operating as a wholly-owned subsidiary of APi Group, Inc. since 1989, the company has evolved into a large-scale structural steel specialist with annual production capacity exceeding 50,000 tons across three AISC-certified facilities. LeJeune serves enterprise general contractors and institutional clients across six vertical markets — commercial buildings, healthcare, distribution centers, sports and entertainment, aviation and aerospace, and data and tech infrastructure — delivering landmark projects such as US Bank Stadium (17,400 tons), Climate Pledge Arena (12,000 tons), EPIC Deepspace (17,000 tons), Amazon Shakopee (11,330 tons), and Northwestern Mutual Tower (8,000 tons).

The company's core offering combines fabrication with in-house design and engineering capabilities: 4 structural engineers, 25+ Tekla 4D modeling experts, and a 12+ person pre-construction team support design-assist, integrated project delivery (IPD), and lump-sum subcontract engagements. Proprietary technology platforms — LookingGlass, the Executive Dashboard, and color-coded 4D models — provide clients real-time piece-level traceability across the fabrication lifecycle, integrated with Trimble Connect and Tekla. Certifications include 40 years of continuous AISC certification and an EMR of 0.64 in 2020, signaling strong safety performance.

LeJeune generates revenue through project-based fabrication and installation contracts, with pricing negotiated individually per project based on tonnage, complexity, and delivery requirements. The go-to-market model relies on enterprise field sales through direct relationships with major national general contractors (Mortenson, Gilbane, Ryan Companies, W.E. O'Neil, JP Cullen, McShane, Power Construction, F.H. Paschen) and design partners (Thornton Tomasetti, HKS, Populous, Gensler). Membership in APi Group provides access to shared corporate resources including bonding, insurance, safety programs, and talent development that are typically unavailable to independent trade contractors. The company is currently executing a 2026 restructuring that relocates corporate headquarters to Minneapolis's North Loop while consolidating factory operations in Wisconsin.
