Alliance Industrial Group

What Alliance Industrial Group does

Alliance Industrial Group, Incorporated (AIG) is a privately held structural steel fabrication and erection company headquartered in Ridgefield, Washington. Founded in 2001 as an erection contractor and expanded in 2007 with the acquisition of Alpha Iron, LLC, the company operates an integrated fabrication-to-erection platform from a single Ridgefield campus that includes 82,000 square feet of interior manufacturing space, 30,000 square feet of exterior fabrication area, rail spur and barge access for oversized work, and robotic CNC beam and pipe profiling lines. AIG holds AISC certifications in Building, Bridge, and Hydraulic fabrication, Erection, and Advanced Fracture Control, Metal Deck, and Seismic endorsements, alongside WABO, AWS, ABS, and City of Los Angeles Type I Fabricator credentials.

The company sells four interrelated offerings: project-based structural steel fabrication and erection for general contractors and facility owners; ancillary services including paint and coatings, seismic retrofits, clean room installations for microprocessor fabs, precast installation, and design/build or design/assist pre-construction support; a Buy-A-Beam e-commerce storefront for raw steel materials and custom fabricated parts targeting SMB and individual buyers; and custom architectural metalwork such as stairways, handrails, furniture, and signage. Pricing is quote-based across all channels with 24-hour turnaround and 7-day quote validity.

AIG's go-to-market combines RFQ-driven direct sales into the Pacific Northwest non-residential construction ecosystem — with named customers including Mortenson Construction, Hoffman Construction, Howard S. Wright, Microsoft, Nike, Sound Transit, Providence Health, Oregon State University, and Portland State University — alongside relationship-led reputation channels, awards-driven credibility (Oregon Manufacturing Award 2013, AISC Safety Performance 2022), and the self-serve Buy-A-Beam channel. The company derives revenue from one-time project contracts, hardware sales through e-commerce, and professional services for design and maintenance work, with no public revenue disclosure.

Direct peers

• Zalk Josephs Fabricators: Long-established structural steel fabricator with comparable AISC program coverage and project-based commercial construction work — a like-for-like competitor on fabricated structural steel.
• TrueNorth Steel: Mid-sized structural steel fabricator serving commercial and industrial contractors, broadly comparable in size, scope, and go-to-market to AIG's fabrication arm.
• Owen Steel Group: Structural steel fabricator with similar scale, AISC certifications, and project-based commercial/industrial construction orientation, making it a closely comparable mid-sized peer.
• Vigor Marine & Industrial: Portland-based structural and marine steel fabricator operating in the same Pacific Northwest market with overlapping AISC certifications and structural steel erection capabilities comparable to AIG.

Others

• Metals Depot: Online metals supplier offering cut-to-size steel products including wide flange, HSS, channel, and plate — directly comparable to Buy-A-Beam's product catalog and self-serve model.
• OnlineMetals: E-commerce platform selling metal materials and small-quantity custom cuts — the closest digital analog to AIG's Buy-A-Beam storefront for steel parts and processing.

Broad incumbents

• EVRAZ North America: Vertically integrated steel producer with structural steel products serving construction — an incumbent competitor on steel supply for fabricated structures.
• Canam Group: Large North American structural steel, joist, and deck manufacturer with national reach and integrated building products — a dominant incumbent in the same fabricated structural metal category.
• Nucor Corporation: Largest US steel producer with structural steel products and fabrication exposure — a vertically integrated incumbent across AIG's raw-material and downstream fabrication space.
• W&W|AFCO Steel: One of North America's largest structural steel fabricators offering a much broader geographic footprint and balance sheet capacity — a scaled incumbent that competes on larger mega-projects AIG cannot fully underwrite.
