What Industrial Steel Construction, Inc. does

Industrial Steel Construction, Inc. (ISC), founded in 1965 and headquartered in Gary, Indiana, is a privately held specialty steel bridge fabricator operating what it describes as the largest single-site bridge fabrication plant in the United States — 1.6 million square feet under roof, 160 acres of staging, 80 overhead cranes, and six miles of active rail track with direct Lake Michigan barge access. The company produces custom plate girders, arch bridges, truss bridges, trapezoidal tub girders, railroad bridges, bascule bridges, and lift spans, using CNC plasma and oxy fuel machines, robotic welding systems, laser tracking accurate to 0.001 inches, and automated vertical girder lines. An integrated 50,000+ square foot blast, paint, and metallizing facility applies three-coat Zinc/Epoxy/Fluoropolymer Urethane and metallizing systems under one roof.

ISC serves state departments of transportation, Class I freight railroads, county and municipal governments, and general contractors across the United States through project-based custom contracts secured via competitive bidding on public infrastructure work. Anchor projects include the 20,000-ton I-74 Bridge over the Mississippi River (2022 Major Span Bridge of the Year), an 8,000-ton Ohio DOT SR8 replacement, the 1,557-foot Eldamain Road Bridge in Kendall County, and the 4,900-ton CREATE 75th Street Corridor in Chicago. The company holds AISC Bridge Fabricator Advanced, Fracture Control, and Complex Coating Endorsements plus NSBA Sophisticated Paint and SSSBA certifications, and employs nearly 300 skilled craftspeople with over 30% of staff tenured more than a decade. Revenue is generated entirely through one-time, multi-year project contracts with no public pricing; financial terms are not disclosed.

Core offering

Industrial Steel Construction fabricates custom steel bridges and structural steel components for highway, railroad, and municipal infrastructure projects from its 1.6 million square foot Gary, Indiana facility using CNC plasma/oxy fuel cutting, robotic welding, automated vertical girder lines, and laser tracking with 0.001-inch accuracy. The company also provides in-house protective bridge coatings through metallizing and three-coat paint systems, and coordinates nationwide delivery of fabricated components via rail, barge, and truck. Service is delivered on a project-based contract basis to state DOTs, Class I railroads, municipalities, and general contractors.

Product overview

Industrial Steel Construction operates as a unified bridge fabrication company offering integrated services centered around steel bridge construction. The core product portfolio consists of four interconnected services: Bridge Fabrication (the primary service using CNC plasma/oxy fuel machines, robotic welding, and laser tracking systems for precision component manufacturing), Bridge Coatings (in-house protective coating application with metallizing and multi-coat systems), Transportation (logistics coordination via rail, barge, and truck leveraging their strategic location near steel mills and transportation networks), and Types of Bridges (expertise across plate girders, arch bridges, truss bridges, tub girders, and movable spans). These services are designed to work together under one roof at their Gary, Indiana facility, enabling end-to-end project delivery from fabrication through coating and shipping.

Broad incumbents

• Nucor Corporation: Largest U.S. steel producer with downstream fabrication capabilities and bridge/structural steel product lines. Comparable as a strategic upstream and adjacent player in the U.S. steel bridge supply chain, though not a direct fabricator competitor to ISC's specialty.
• Canam Steel: Large North American steel fabricator serving bridges, buildings, and industrial structures with multi-site capacity. Overlaps with ISC in bridge steel fabrication but operates a broader structural steel portfolio across multiple geographies.

Direct peers

• SteelFab: Southeast U.S. structural steel fabricator with significant bridge and infrastructure work for DOTs and contractors. Comparable in scale, AISC certifications, and project-based revenue model with highway and bridge customers.
• High Steel Structures: Pennsylvania-based AISC Advanced certified bridge fabricator producing plate girders, rolled beams, and complex steel spans for state DOTs. Closely comparable in certification stack, customer base, and project scale.
• W&W AFCO Steel: Oklahoma-based structural and bridge steel fabricator producing plate girders, trusses, and bridge components for highway and rail projects. Directly comparable in AISC-certified bridge fabrication for public-sector customers.
• Stupp Bridge Company: Missouri-based steel bridge fabricator supplying plate girders and fabricated structural steel to state DOTs and contractors across the U.S. Closely comparable in product mix, certifications, and project-bid business model.
• Veritas Steel: One of the largest steel bridge fabricators in North America, producing plate girders, tub girders, and arch bridges for U.S. DOTs and Class I railroads. Directly comparable to ISC in product scope, customer base, and AISC-certified mega-project delivery.
• Hirschfeld Industries: Texas-based structural steel fabricator serving bridges, highways, and industrial structures with AISC certification. Comparable in serving public-sector infrastructure customers with large-scale fabricated steel components.
• Maico Industries: Wisconsin-based AISC-certified structural steel and bridge fabricator producing plate girders and fabricated assemblies for highway and rail bridges. Comparable in Midwestern location, product mix, and public-sector customer base.

Regional players

• Supermetal Structures: Canadian structural steel fabricator with bridge capabilities serving North American infrastructure projects. Comparable in bridge fabrication scope and AISC-style certifications, primarily operating in Canada but competing for cross-border mega-projects.
