DONALDSONVILLE, La. — Hyundai Steel and South Korea’s Posco joined Louisiana officials Friday to break ground on a $5.8 billion electric-arc furnace steel mill that company leaders say will supply automotive-grade steel to U.S. carmakers and establish a large manufacturing foothold in the United States.
Project scope and timeline
The venture, named Hyundai-Posco Louisiana Steel (HPLS), is a joint effort backed by Hyundai Steel and Posco, with additional support from Hyundai Motor and Kia. Company and government representatives said the plant will have an annual production capacity of 2.7 million metric tons of steel sheet and is expected to enter commercial operations in 2029.
Officials held a ceremonial groundbreaking in Donaldsonville, where attendees included Louisiana Gov. Jeff Landry, U.S. Under Secretary of Commerce for International Trade William Kimmitt, U.S. Reps. Troy Carter and Julia Letlow; South Korea’s Minister of Trade, Industry and Resources Kim Jung-kwan; and Korean Ambassador to the United States Kang Kyung-wha. Hyundai Motor Group Executive Chair Chung Euisun and Posco Group Chair Chang In-hwa represented the corporate partners.
Economic and industrial implications
State and company leaders framed the plant as a major step in reshoring advanced steel manufacturing tied to the auto supply chain. The facility will be the first integrated mill in the U.S. dedicated to producing automotive steel sheet, according to Hyundai Motor Group leadership at the event.
Local officials hope the project will bring both construction and longer-term manufacturing employment, boost the regional industrial base and attract related suppliers. The announcement follows initial plans revealed at the White House in March 2025, underscoring multi-year negotiations and planning between the companies and governmental partners.
What company leaders said
“This plant will be both our company’s first integrated steel mill dedicated to automotive steel sheet and the first of its kind in America,” Chung Euisun said at the ceremony. “The steel produced here will support Hyundai Motor Group and other automakers as they build the next generation of mobility.”
The presence of senior trade and diplomatic officials from both countries reflected the strategic scale of the investment and its role in trans-Pacific industrial ties.
Practical details and public interest
While company statements provided production capacity and a target start year, specific details — including final employment numbers, incentive agreements, environmental permits and construction schedules — were not disclosed in full at the ceremony. Local residents and public-interest groups will be watching for permitting documents, environmental reviews and job commitments as the project moves into construction.
- Investment: $5.8 billion

State economic development officials previously worked to secure large-scale industrial projects through incentive packages and infrastructure support; such arrangements typically include tax and workforce-development components. The terms specific to HPLS have not been released in full at the time of the groundbreaking.
Next steps and community considerations
As construction proceeds, the public will have opportunities to review environmental assessments and permitting filings required by state and federal agencies. Community stakeholders often focus on traffic, emissions, water use, noise and job quality — issues that will be reviewed during the permitting and inspection processes.
The project adds to a national trend of major industrial investments tied to efforts to secure domestic supply chains for advanced manufacturing and transportation. For Donaldsonville and surrounding parishes, the immediate impacts will include construction activity followed by the longer challenge of integrating a large steel plant into the regional economy.
Reporting from the event was provided in part by company releases and statements from state and federal officials present at the ceremony.
