DeLong's

What DeLong's does

DeLong's, Inc. is a family-owned, third-generation structural steel fabricator headquartered in Jefferson City, Missouri. Founded in 1944, the company operates two manufacturing facilities in Missouri — a 338,000-square-foot Jefferson City plant holding AISC Certified Bridge Fabricator – Advanced (ABR) status with Sophisticated Paint Endorsement and Fracture Critical Endorsement, and a 93,000-square-foot Sedalia plant holding AISC Intermediate Bridge Fabricator (IBR) certification. Across roughly 200 employees, DeLong's produces plate girders, wide flange beams, trusses, expansion joints, elastomeric and steel bearings, ornamental railings, and miscellaneous structural components for highway, railroad, pedestrian, commercial, and residential applications.

The business runs a fully integrated, in-house production model: four registered professional engineers provide design-build assistance, six drafting technicians with over 100 years of combined tenure produce shop drawings for more than 90% of projects, CNC machining is used for complex bearings, and climate-controlled paint shops at both facilities support high-specification finishing. Turnkey delivery — engineering, detailing, fabrication, and painting under one roof — is the central technical differentiator, alongside compliance with AREMA, AWS, and AISC fracture-critical requirements.

Revenue is generated through project-based, quote-driven contracts awarded via direct sales to state Departments of Transportation, Class I railroads (BNSF, Union Pacific, Norfolk Southern), general contractors, and individual builders/owners. Distribution is purely domestic and direct, with no intermediaries or retail channels. Pricing is not publicly disclosed and varies by tonnage and specification. Marketing relies on industry events, AISC/NSBA/SSSBA/AGCMO association memberships, a project portfolio website, and dedicated phone-based sales lines for bridge, commercial, and residential inquiries.

Direct peers

• Lexicon Group: Lexicon (formerly Precision Metal Fabricating) is a structural steel fabricator focused on bridges, commercial, and industrial projects. Directly overlaps with DeLong's in plate girder fabrication, AISC certification scope, and customer mix.
• Hirschfeld Industries: Hirschfeld Industries is a structural steel fabricator with bridge, industrial, and commercial capabilities across multiple U.S. plants. It directly competes with DeLong's in plate girder and bridge fabrication for state DOT and rail customers.
• Prospect Steel: Prospect Steel is a structural and miscellaneous metals fabricator serving commercial and infrastructure projects in the Midwest. Comparable to DeLong's in offering beams, columns, stairs, and railings for general contractors and DOT projects.
• Owen Industries: Owen Industries is a Midwest-based structural steel fabricator serving bridge, commercial, and industrial markets. It is comparable to DeLong's in offering structural steel fabrication with in-house detailing and painting for DOT, rail, and commercial customers.
• AFCO Steel: AFCO Steel is a structural and bridge steel fabricator based in Little Rock, AR. DeLong's and AFCO partnered on the I-40 White River bridge project, indicating both firms operate as direct competitors and occasional collaborators on large multi-thousand-ton bridge jobs.
• Stupp Bridge Company: Stupp Bridge is one of the largest bridge steel fabricators in the U.S., headquartered in St. Louis. Directly competes with DeLong's for DOT bridge plate girder work and has even co-hosted industry events with DeLong's, indicating close overlap in customers, geography, and capabilities.
• Veritas Steel: Veritas Steel is a large bridge steel fabricator operating multiple facilities in the Midwest and Northeast. It competes directly with DeLong's for state DOT and Class I railroad bridge projects, with comparable plate girder and rolled beam capabilities.

Broad incumbents

• Gerdau Ameristeel: Gerdau operates steel mills and fabrication operations across the Americas. As a broad incumbent, it overlaps with DeLong's on raw steel supply and select fabricated structural products, but does not specialize in AISC-certified bridge fabrication at DeLong's scale.
• Nucor Corporation: Nucor is the largest U.S. steel producer with downstream fabrication capabilities. While not a direct bridge fabricator like DeLong's, it operates in the same steel value chain and occasionally bids on fabricated structural packages that compete with regional fabricators.
• Cives Steel Company: Cives Steel is a diversified structural steel fabricator with plants across the U.S. and Canada serving bridge, commercial, and industrial customers. It is comparable to DeLong's as a multi-plant fabricator competing for similar DOT and commercial bids, but at a broader scale.
