Hyundai Steel Louisiana Mill Breaks Ground at $5.8 Billion

Hyundai Steel Breaks Ground on Louisiana Steel Mill

Hyundai Steel Company held a ceremonial groundbreaking event on September 4 for its $5.8 billion Electric Arc Furnace-based integrated steel mill in Ascension Parish, Louisiana. The facility is positioned as the first integrated steel mill of its kind in North America and will be operated by HYUNDAI-POSCO Louisiana Steel LLC (HPLS). The project represents a major manufacturing investment focused on producing steel sheets for automotive and other applications. The Hyundai Steel Company facility is scheduled to begin commercial production in 2029, establishing a new integrated steel production base for Hyundai Motor Group in the region.

Joint Venture Structure and Production Capacity

HYUNDAI-POSCO Louisiana Steel LLC is structured as a joint venture involving four companies. Hyundai Steel Company holds a 50% stake, while Posco owns 20%, and Hyundai Motor and Kia Corporation each hold 15%. Once commercial production begins in 2029, the mill is expected to have annual capacity of 2.7 million metric tons of hot-rolled and cold-rolled steel sheets. Approximately 1.8 million metric tons of that output will be automotive steel, while the remaining 900,000 metric tons will serve other applications.

Automotive Steel Supply for Hyundai and Kia

The new mill is expected to support a more stable automotive steel supply for Hyundai Motor and Kia assembly operations in Alabama and Georgia. By producing steel sheets within the United States, the project is intended to strengthen the companies' ability to supply their vehicle manufacturing operations while supporting efforts to expand sales in the North American market. The facility therefore connects steel production directly with downstream vehicle manufacturing needs, giving the Hyundai Motor and Kia Corporation operations a dedicated source of automotive steel as the new facility moves toward its targeted production start.

First Integrated Mill Dedicated to Automotive Steel Sheet

Hyundai Motor Group Executive Chair Chung Euisun Chung described the project as a significant milestone for both the company and the broader automotive manufacturing sector. “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,” said Hyundai Motor Group Executive Chair Chung Euisun Chung. He added, “The steel produced here will support Hyundai Motor Group and other automakers as they build the next generation of mobility.” The statements highlight the project's intended role in supplying automotive steel while supporting future vehicle production.

Louisiana Facility Targets 2029 Commercial Production

The Ascension Parish project combines Electric Arc Furnace-based steelmaking with integrated production of hot-rolled and cold-rolled steel sheets. Its planned 2.7 million-metric-ton annual capacity establishes a substantial production base, with automotive steel accounting for the majority of the expected output. The Louisiana location also places the facility within reach of Hyundai Motor and Kia assembly operations in Alabama and Georgia, creating a regional connection between steel manufacturing and vehicle production. With commercial operations targeted for 2029, the project's next major milestone will be advancing construction toward the planned production timeline.

Industry Impact & Outlook

The Louisiana mill could strengthen Hyundai Motor Group's regional automotive manufacturing supply chain by adding dedicated domestic steel production alongside its assembly footprint in the southeastern United States. Its planned emphasis on automotive steel may reduce reliance on external sources for a significant portion of the group's steel-sheet requirements and provide greater supply coordination for plants in Alabama and Georgia. The project may also increase the importance of integrated steelmaking capacity in North American automotive manufacturing as automakers pursue more localized supply networks. The key near-term focus will remain construction progress and the ability to reach the targeted 2029 commercial production date.

Frequently Asked Questions

What is the Hyundai Steel Louisiana Mill?
The Hyundai Steel Louisiana Mill is a planned $5.8 billion Electric Arc Furnace-based integrated steel facility in Ascension Parish, Louisiana. Hyundai Steel Company held its ceremonial groundbreaking event for the project on September 4, marking the start of development for an integrated mill designed to produce automotive and other steel sheets. The facility will be operated by HYUNDAI-POSCO Louisiana Steel LLC, a joint venture involving Hyundai Steel, Posco, Hyundai Motor, and Kia Corporation. Commercial production is targeted for 2029, with planned annual capacity of 2.7 million metric tons.

How much steel will the Louisiana mill produce annually?
The planned Louisiana facility will have annual production capacity of 2.7 million metric tons of hot-rolled and cold-rolled steel sheets once commercial operations begin. About 1.8 million metric tons of the output is expected to be automotive steel, while approximately 900,000 metric tons will be allocated to other applications. This production plan makes automotive steel the primary output of the facility and supports its stated role within Hyundai Motor Group's regional manufacturing strategy. Commercial production is currently targeted for 2029, following construction and development of the integrated mill.

Which companies own the Louisiana steel mill joint venture?
HYUNDAI-POSCO Louisiana Steel LLC will operate the Louisiana mill through a four-company ownership structure. Hyundai Steel Company holds a 50% stake, Posco owns 20%, and Hyundai Motor and Kia Corporation each hold 15%. The structure brings together steelmaking and automotive manufacturing companies within the same project, linking the planned steel supply with vehicle production operations. The facility is intended to provide automotive steel for Hyundai Motor and Kia assembly plants in Alabama and Georgia while also supporting broader sales expansion in the North American market.
