Mesabi Metallics has proposed a $15 billion steel plant in Lee County, Iowa, which would be the largest steel plant ever built in the U.S. and is expected to come online by 2030 with 1,700 permanent jobs.
Why it matters
For Iowa operators, a project of this scale could reshape local supply chains, labor markets, and demand for contractors and industrial services in southeast Iowa. The proposal arrives as Lee County has lost more than 6% of its population since 2010, making the workforce and economic-base question central to local planning.
The proposed plant carries a $15 billion price tag and is projected to create 1,700 permanent jobs at $48 an hour, against a Lee County population that fell more than 6% between 2010 and 2020. Mesabi Metallics also projects roughly $95 billion in economic impact over the project's life, though these figures come from the company and have not been independently verified.
The players
Mesabi Metallics
A steel producer pursuing a $15 billion plant that would be the largest steel facility ever built in the U.S., using a process the company says sharply reduces carbon output.
Essar Group
A multinational industrial conglomerate with interests in steel and energy that owns Mesabi Metallics.
Lee County Board of Supervisors
The local governing body in Lee County, Iowa, that is reviewing the proposed plant and hosted a public Q&A on the project.
The details
Mesabi Metallics, owned by the Essar Group, says its steelmaking process cuts carbon output by 60-70% compared with conventional methods. The company has filed a preliminary air permit intended to comply with state and federal regulations, a step that will be central to whether the project advances on its stated timeline. The Lee County Board of Supervisors has held a Q&A session on the proposal, signaling local review is underway.
Timeline
Earlier this fall (2026): The White House announced the $15 billion steel plant.
End of 2027: Target date for Mesabi Metallics to break ground on the facility.
2030: Plant expected to be online, with 1,700 permanent jobs.
Market Landscape
If built as projected, the plant would rank as the largest U.S. steel facility, placing Mesabi Metallics and the Essar Group in a new category of domestic capacity. The proposal's carbon-reduction claims also place it within the broader push by steelmakers to market lower-emission production methods.
Iowa contractors, industrial suppliers, and logistics firms in the southeast region should watch for early procurement and staffing opportunities tied to construction. Businesses that compete for skilled labor should monitor how a $48-an-hour wage benchmark may shift local hiring rates.
The takeaway
Treat the 1,700-job and $95 billion figures as company projections until the air permit and construction timeline are confirmed. Operators in manufacturing supply and skilled trades should track the permit status and the 2027 groundbreaking target as the signals that matter most.
What happens next
Mesabi Metallics' stated target is to break ground on the facility by the end of 2027, a milestone operators and local officials can track against the pending air permit.
