Future Projections
By 2028, the U.S. expects 125-130 steel plants (up from 114 in 2026).
Most growth will come from new EAF facilities focused on sustainability.
Integrated mills will continue to decline - only 5 expected to remain by 2030.
There are 114 active steel plants in the United States as of early 2026. That number includes integrated mills, electric arc furnace (EAF) facilities, and specialty steel producers. It’s not a static figure-plants close, merge, or upgrade every year, so the count shifts slightly. But 114 is the current working total based on data from the American Iron and Steel Institute (AISI) and the U.S. Energy Information Administration (EIA).
What Counts as a Steel Plant?
Not every facility that makes steel is the same. Some are massive, full-service integrated mills that start with iron ore and coal. Others are smaller EAF plants that melt scrap metal. Both count as steel plants, but they operate very differently.
An integrated steel mill, like U.S. Steel’s Gary Works in Indiana, uses blast furnaces to turn raw materials into steel. These are energy-heavy and require huge infrastructure. There are only 12 of these left in the U.S. today, down from over 50 in the 1980s.
Electric arc furnace plants make up the majority now-about 80% of U.S. steel production. They don’t need iron ore. Instead, they recycle scrap steel from cars, appliances, and construction debris. These plants are cheaper to run and can start up quickly. They’re often located near cities or rail hubs where scrap is easy to collect.
Then there are specialty producers. These make high-grade steel for aerospace, medical tools, or pipelines. Companies like Nucor’s thin slab caster in Mississippi or ArcelorMittal’s flat-rolled facility in Indiana fall into this group. They’re fewer in number but critical for high-tech industries.
Where Are the Steel Plants Located?
The U.S. steel industry isn’t spread evenly. Most plants cluster around the Great Lakes and the Midwest, where rail and water transport make it easy to move raw materials and finished products.
Pennsylvania, Ohio, Indiana, Illinois, and Alabama together host nearly half of all U.S. steel plants. Pennsylvania alone has 11 active facilities, including Nucor’s plate mill in Johnstown and a historic U.S. Steel plant in Clairton. Ohio has 10, with major EAF operations in Cleveland and Youngstown.
The Gulf Coast is growing fast. Texas has 9 steel plants, mostly near Houston and Corpus Christi, serving the oil and gas industry. Alabama’s Port of Mobile is home to two major mills, including the $2.1 billion Nucor facility that opened in 2023.
California, Florida, and Washington have smaller clusters. California’s 4 plants focus on specialty steel for defense and tech. Florida’s 3 are mostly EAFs that serve construction and infrastructure projects.
Some states have zero active steel plants. Vermont, Maine, and North Dakota don’t have any. That doesn’t mean they don’t use steel-they import it. But no steel is made there.
How Much Steel Do These Plants Produce?
It’s not just about how many plants there are-it’s about how much they make. In 2025, U.S. steel mills produced 85.6 million metric tons of crude steel. That’s about 5% of global production, but it’s enough to cover most domestic needs.
Integrated mills still produce about 30% of that total, even though they’re only 12 plants. They’re big and slow, but they make the heavy plate and beam steel used in bridges, ships, and pipelines.
EAF plants, with their 102 facilities, made 70% of the steel. They’re faster, more flexible, and increasingly efficient. Modern EAFs can turn scrap into finished steel in under an hour. Some even use hydrogen-based direct reduction tech to cut emissions.
Steel production per plant varies wildly. A single large EAF can make 2 million tons a year. A small specialty mill might only make 100,000. The average U.S. steel plant produces about 750,000 tons annually.
Why the Number Keeps Changing
The steel industry is in flux. Plants don’t just shut down-they get upgraded, repurposed, or bought out.
In 2024, a small EAF in Ohio shut down after 60 years. The land was sold for a solar farm. At the same time, Nucor broke ground on a new $1.3 billion mill in Georgia, its first in the Southeast. That’s replacing a closed facility in North Carolina.
Foreign investment is also changing the map. In 2025, a joint venture between ArcelorMittal and a South Korean firm opened a new cold-rolled plant in South Carolina. It’s not a new plant per se-it replaced an older one-but it counts as a new facility in industry reports.
There’s also pressure to decarbonize. The U.S. government’s Inflation Reduction Act offers tax credits for low-emission steel production. That’s pushing older plants to retrofit or shut down. New plants are being built with hydrogen-ready designs.
Who Owns These Plants?
Three companies control about 60% of U.S. steel production: Nucor, U.S. Steel, and ArcelorMittal USA.
Nucor leads the pack with 38 plants. It’s the largest steel producer in North America and the only one that’s 100% EAF-based. Its plants are spread across 22 states. It’s also the most aggressive about building new facilities-2 new mills opened in 2024 and 2025.
U.S. Steel, once the giant of American industry, now runs 15 plants. It still owns the last major integrated mills. But it’s been selling off older assets. Its Clairton, PA coke plant closed in 2023. Its Gary Works remains operational, though it’s now owned by a private equity firm after a failed merger.
ArcelorMittal USA operates 12 plants, mostly in the Midwest and Gulf Coast. It’s the only one with a major presence in the East Coast, thanks to its plant in Indiana and the new South Carolina facility.
The rest-about 50 plants-are owned by smaller companies: Commercial Metals, Steel Dynamics, and a handful of regional producers. Some are family-owned for generations. Others are subsidiaries of foreign firms like Japan’s Nippon Steel or India’s JSW Steel.
What’s Next for U.S. Steel Plants?
The next five years will see major shifts. The U.S. is pushing for more domestic steel production to support infrastructure, defense, and clean energy.
By 2028, analysts expect the number of steel plants to rise to 125-130. Most of the growth will come from new EAF facilities. The Department of Energy has committed $4.2 billion to support low-carbon steel projects. That includes funding for hydrogen-based direct reduction, carbon capture, and scrap recycling tech.
Older integrated mills will keep closing. Only 5 of the remaining 12 are expected to still be running by 2030. The rest will be replaced by modern EAFs with lower emissions and higher efficiency.
One thing is clear: the U.S. steel industry is becoming leaner, cleaner, and more focused on recycling. The number of plants might go up, but the way they work is changing completely.
Are all steel plants in the U.S. still operating?
No. About 8-10 steel plants in the U.S. are permanently closed or in the process of being decommissioned. These are usually older integrated mills that can’t compete with modern EAFs. Some are being converted into logistics centers or renewable energy sites. The active count as of 2026 is 114.
Which state has the most steel plants?
Pennsylvania has the most active steel plants with 11, followed closely by Ohio with 10. Both states have deep industrial histories and strong rail networks that support steel production. However, Texas and Alabama are catching up fast due to new investments.
Do U.S. steel plants use imported materials?
Yes. While most EAF plants use scrap steel collected domestically, integrated mills still rely on imported iron ore and coking coal. About 25% of raw materials for integrated mills come from Canada, Brazil, and Australia. EAFs, which use scrap, are far less dependent on imports.
How has the number of steel plants changed over the last 20 years?
In 2006, there were about 140 active steel plants. By 2016, that dropped to 120 due to closures and consolidation. Since 2016, the number has stabilized and is now rising again thanks to new EAF investments. The trend isn’t just about fewer plants-it’s about better, cleaner, and more efficient ones.
Can the U.S. meet its steel demand with domestic plants?
Yes, but barely. U.S. mills produce about 85 million tons of steel a year. Domestic demand is around 80 million tons. The surplus is small, and any spike in construction or defense needs can strain supply. That’s why new plants are being built-to reduce reliance on imports and avoid shortages.
