Facility History and Overview

Origins and Growth of the Ecorse Steel Complex

Steel production in Ecorse dates to the early twentieth century, when the western shore of the Detroit River attracted heavy industrial development.

1920s — Great Lakes Steel Corporation was established and grew into one of the region’s dominant steel producers
Location — Direct waterway access enabled iron ore shipments from the Upper Great Lakes and finished steel delivery to automotive manufacturers throughout the Midwest
Mid-to-late twentieth century — The facility operated under the National Steel Great Lakes Division banner following corporate mergers and consolidations
Peak operations — The Ecorse complex employed thousands of workers across multiple production units, many represented by the United Steelworkers (USW) and craft locals, including Heat and Frost Insulators Local 1 members who performed comparable work at regional facilities in Missouri and Illinois

Production Operations

At peak capacity, the facility included:

Blast furnaces operating above 2,000 degrees Fahrenheit
Basic oxygen furnaces (BOFs)
Coke ovens
Rolling mills
Casting operations
Maintenance and repair departments running 24 hours a day, year-round

Corporate History and Workforce Scale

Late 1980s — Nippon Kokan (NKK) acquired a majority interest in National Steel
2002 — National Steel Corporation filed for bankruptcy protection
Post-bankruptcy — United States Steel Corporation acquired most National Steel assets and continued operations as Great Lakes Works
Workforce — Union members of the USW and craft trades, including affiliates of Heat and Frost Insulators Local 1 and Plumbers and Pipefitters UA Local 562 (St. Louis, MO), numbered in the tens of thousands at various points — a large population of workers who may have been exposed to asbestos-containing materials over the course of their careers

Why Asbestos-Containing Materials Were Installed in Steel Production

The Heat Problem

Steel manufacturing runs at temperatures that destroy most materials. Facilities like this one required:

Blast furnaces above 2,000 degrees Fahrenheit
Coke ovens, basic oxygen furnaces, soaking pits, reheating furnaces, and ladles handling molten steel
Extensive steam pipe networks, high-pressure lines, turbines, and boilers throughout the plant

Why Asbestos Dominated Steel Plant Infrastructure

ACM handled these extreme conditions cheaply and reliably. The specific properties that drove its widespread adoption:

Thermal insulation — Withstood temperatures that destroyed available alternatives before the 1970s
Fire resistance — Resisted ignition in environments where combustion risks were constant
Chemical durability — Held up against acids, alkalis, and corrosive substances common in steel production
Mechanical versatility — Could be woven into textiles, mixed into gasket compounds, incorporated into cement products, and sprayed as insulating coatings
Cost efficiency — Inexpensive and abundantly available through most of the twentieth century

Asbestos manufacturers knew about these health risks for decades and chose profit over worker safety. That is what this litigation is about.

The Exposure Window: 1930s Through 1990s

1930s–mid-1970s — Peak era of ACM installation at steel facilities nationwide
Early 1970s forward — OSHA began establishing asbestos exposure standards; health hazard awareness increased among regulators, though not necessarily on the shop floor
Mid-1975 onward — New ACM installations declined significantly
1980s–1990s — Materials already in place remained in service, creating ongoing exposure during maintenance, repair, demolition, and renovation work

Workers who tore out old insulation, disturbed fireproofing during construction projects, or worked around deteriorating ACM may have faced repeated exposure long after new installations stopped. The latency period for mesothelioma — typically 20 to 50 years — means workers exposed in the 1970s and 1980s are being diagnosed right now.

High-Risk Trades and Occupational Exposure

Insulators — Highest Exposure Risk

Insulators at the Ecorse facility, including members of Heat and Frost Insulators Local 1 and comparable locals serving Missouri facilities, may have faced among the highest ACM exposure levels of any trade group. Their work included:

Installing, maintaining, and removing thermal insulation from pipes, boilers, turbines, and process equipment
Cutting pipe insulation sections to length — a dry, dusty operation that reportedly generated heavy airborne fiber concentrations
Mixing and applying insulating cement by hand
Stripping old, deteriorated insulation during maintenance shutdowns

Insulators who worked during the peak ACM era are now heavily represented in mesothelioma diagnoses nationwide. If you are an insulator or the family member of one, your risk of a compensable claim is real.

Pipefitters and Steamfitters — Chronic, Cumulative Exposure

Pipefitters and steamfitters, including members of Plumbers and Pipefitters UA Local 562 (St. Louis, MO) and Plumbers and Pipefitters UA Local 268 (Kansas City, MO), worked throughout the facility’s piping systems and may have faced repeated exposure through:

Breaking and remaking flanged connections — each break reportedly disturbed asbestos-containing gasket materials
Replacing valves in steam and process piping systems
Handling asbestos-containing valve packing, pump packing, and mechanical seal materials

Years or decades of this work produced chronic, cumulative exposure that courts and asbestos trust funds have recognized as compensable.

Boilermakers and Refractory Workers

Boilermakers and refractory specialists may have faced direct contact with:

Asbestos-containing refractory cements, mortars, and castables in blast furnace, coke oven, and soaking pit linings
Asbestos-containing rope gaskets and woven textile seals in furnace doors, inspection ports, and access hatches
Installation, repair, and demolition of furnace linings and related structures

These workers reportedly handled ACM-rich materials on a regular basis throughout their careers.

Maintenance Mechanics and General Laborers

Maintenance mechanics and general laborers throughout the facility may have been exposed when:

Performing routine equipment maintenance near asbestos-insulated pipes and equipment
Handling and moving insulated components
Working in areas where ACM was deteriorating and releasing fibers into the air
Assisting in renovation and demolition affecting sprayed fireproofing or other ACM

Bystander exposure — being near someone else’s ACM work — is legally compensable and has supported successful claims in both litigation and trust fund submissions.

Electricians

Electricians at the facility may have encountered asbestos-containing materials through:

Wire and cable insulations manufactured with asbestos jacket materials
Arc chutes in electrical switchgear and panels
Thermal insulation surrounding large motors, transformers, and other electrical equipment requiring heat management

Additional Trades

Other workers who may have encountered asbestos-containing materials include:

Millwrights — Equipment installation and maintenance throughout the plant
Welders — Routine work near asbestos-insulated pipes, structures, and equipment
Carpenters — Handling asbestos-containing building materials, Transite board, and fireproofing products
Operators and technicians — Working in areas with asbestos-containing equipment during normal production and during shutdowns

Asbestos-Containing Materials Allegedly Present at the Facility

Based on asbestos litigation discovery documents from comparable integrated steel facilities including Granite City Steel/U.S. Steel (Granite City, IL) and Laclede Steel (Alton, IL), publicly filed trust fund records, and well-established industry knowledge of steel production practices during the relevant period, numerous asbestos-containing materials were reportedly present at the National Steel Great Lakes Division.

Thermal Insulation Products

Pipe and Equipment Insulation

Workers at this facility may have been exposed to asbestos-containing insulation including:

High-pressure steam system and hot water line insulation covering miles of piping throughout the plant
Pipe blocking and sectional insulation products allegedly manufactured by:
- Owens-Illinois (Kaylo brand)
- Johns-Manville (Thermobestos and related thermal insulation products)
- Armstrong World Industries
- Eagle-Picher Industries

Disturbing these materials during maintenance and repair work reportedly generated substantial airborne fiber concentrations — concentrations that manufacturers knew were dangerous and concealed from workers for decades.

Asbestos-Containing Cement Products

Pipe sections and fittings were frequently covered with asbestos-containing cement compounds applied by insulators
These hardened coatings, when chipped, cut, or ground during repair work, reportedly released respirable asbestos fibers directly into the breathing zones of workers

Refractory and Furnace Materials

Refractory Cements and Mortars

Linings of blast furnaces, basic oxygen furnaces, coke ovens, soaking pits, and reheating furnaces reportedly incorporated asbestos-containing refractory cements and castables
Boilermakers and refractory workers who installed, repaired, or demolished these linings may have been exposed to high concentrations of airborne fibers

Furnace Door Seals and Gaskets

Furnace doors, inspection ports, and access hatches were sealed with asbestos-containing rope gaskets and woven textile seals
Compressed sheet gasket materials from manufacturers including:
- Garlock Sealing Technologies
- Crane Co.
- Flexitallic (reportedly a manufacturer of asbestos-containing compressed sheet gaskets)

Workers who replaced these seals as part of routine maintenance reportedly faced repeated, ongoing exposure throughout the life of the facility.

Castable Refractory Products

Poured and troweled asbestos-containing refractory materials were reportedly used to form and repair furnace linings, hearths, and tapping areas throughout the steel production process

Gaskets, Packing, and Valve Materials

Sheet Gasket Materials

Compressed asbestos sheet gaskets were standard components in virtually all high-temperature and high-pressure flanged connections throughout the facility
Every time a flanged connection was broken and remade — which occurred repeatedly during normal maintenance — workers may have been exposed to asbestos-containing materials
Pipefitters and maintenance mechanics who performed this work routinely may have accumulated substantial exposure over the course of a career

Valve Packing Materials

Valves throughout the facility’s steam and process piping systems were reportedly packed with asbes
