Mesabi Metallics Plans $15 Billion Iowa Steel Plant in Major U.S. Manufacturing Expansion
Mesabi Metallics has announced plans to invest $15 billion in a new steelmaking complex in eastern Iowa, creating what the company and U.S. officials describe as one of the largest steel projects in American history. The announcement was made at the White House on September 28, 2026, with the project expected to connect Mesabi’s newly opened Minnesota iron-ore operation with steel production in Iowa.
The Iowa investment forms part of an overall $18 billion development program. About $3 billion is allocated to completing Mesabi Metallics’ iron-ore mine and pellet plant near Nashwauk, Minnesota, while the remaining $15 billion is earmarked for the Iowa steel complex. The company says the resulting supply chain will run from mining in Minnesota to steel production in Iowa and supply American manufacturers.
The proposed plant is expected to begin steel production in 2030. Its first phase is projected to produce approximately 7.5 million tons of steel annually, with later expansion potentially increasing capacity to about 10 million tons a year. The White House has described the fully developed facility as potentially the largest steel plant in the United States.
Mesabi Metallics expects the Iowa project to create approximately 1,750 permanent jobs and support as many as 6,000 construction jobs. The company estimates that the project could generate about $95 billion in economic output during construction and its first decade of operation.
The planned facility is designed around direct-reduced iron and electric-arc-furnace technology. According to the company, Minnesota-produced iron-ore pellets will be transported to Iowa, where they will be processed into steel alongside recycled scrap. The approach is intended to create an integrated domestic supply chain rather than relying on imported steel or foreign-produced intermediate materials.
A major part of the project’s significance lies in Mesabi Metallics’ recently opened Minnesota mine. The mine represents Minnesota’s first new iron-ore mine in roughly half a century and is expected to provide the raw material for the Iowa operation. The company has invested about $2.5 billion in the Minnesota development and has received significant federal financing support for its expansion.
The project is backed by Essar Group, the India-based industrial conglomerate that owns Mesabi Metallics. The company has described the combined Minnesota-Iowa development as a vertically integrated American steel supply chain, with the ore mined domestically and converted into finished steel within the United States.
The decision to locate the steel complex in Iowa rather than Minnesota has nevertheless generated discussion in the Iron Range region. Minnesota officials and residents have welcomed the economic significance of the new mine but some have expressed disappointment that the next major stage of investment will take place in Iowa. Mesabi chief executive Joe Broking has argued that the Iowa facility will strengthen the long-term economics of the Minnesota mine by connecting it to a large steelmaking operation.
The choice of Iowa also reflects infrastructure and energy considerations. The proposed eastern Iowa location provides access to the Mississippi River for transportation, while electricity costs are an important factor in electric-arc-furnace steelmaking. Reports indicate that Iowa’s commercial electricity prices are somewhat lower than Minnesota’s, although the company has not publicly provided a single explanation for selecting the state.
The announcement comes as the U.S. steel industry faces a combination of strong domestic-policy support, international overcapacity and continuing competition from imported steel. The Trump administration has emphasized tariffs and domestic manufacturing as tools for encouraging investment in American production. Reuters reported that U.S. steel prices have remained elevated amid trade barriers, potentially improving the economics of new domestic steel projects despite their substantial construction costs.
For Iowa, the project could represent a major addition to the state’s industrial base if construction and financing proceed as planned. For Minnesota, the steel plant provides a large potential customer for the newly developed Nashwauk mine and could help establish a longer-term market for its iron-ore pellets.
The project remains a plan rather than an operating steel facility, and major stages including site development, permitting, construction and financing must still be completed before production begins. If the announced timetable is achieved, Mesabi Metallics expects the first Iowa steel to be produced in 2030, creating a new integrated mining-to-steel supply chain across Minnesota and Iowa.
