POSCO to Boost Automotive Steel With New Galvanizing Plant
Read MoreHide Full Article
Key Takeaways
PKX broke ground on 8CGL, a 450,000-ton automotive galvanized steel line due in 2028.
PKX will produce extra-wide steel sheets for exterior panels of midsize and larger SUVs and RVs.
AI, robotics and EAF integration aim to improve efficiency and support lower-carbon automotive steel.
POSCO Holdings Inc. (PKX - Free Report) is investing KRW 480 billion to build a new state-of-the-art hot-dip galvanized automotive steel sheet plant at its Gwangyang Works in South Korea. The project is aimed at expanding premium automotive steel capacity while integrating advanced AI, robotics and lower-carbon production technologies.
POSCO’s New 8CGL Plant to Add 450,000 MT of Capacity
POSCO broke ground on its No. 8 Continuous Galvanizing Line (8CGL) at Gwangyang Works on Sept. 8, 2026. The facility is scheduled for completion in 2028 and will have an annual production capacity of 450,000 metric tons of hot-dip galvanized steel sheets.
The new line will focus primarily on galvanized steel for automotive exterior panels. Hot-dip galvanizing involves coating steel with zinc, improving its corrosion resistance, surface quality, paintability and formability. These characteristics make the material particularly suitable for vehicle body panels, where durability and appearance are important.
Once 8CGL becomes operational, POSCO's total annual hot-dip galvanized steel production capacity is expected to increase to 4.95 million metric tons.
PKX Focuses on Premium and Larger Vehicles
The investment comes as automakers increasingly demand higher-quality steel for premium and larger vehicles. POSCO plans to use the new line to produce extra-wide steel sheets designed for exterior panels of midsize and larger SUVs and recreational vehicles.
The shift toward larger and more premium vehicles is creating demand for steel that can deliver a combination of surface quality, corrosion resistance and formability. 8CGL is designed to address these requirements while strengthening its competitiveness in next-generation automotive materials.
POSCO Integrates 8CGL With New Electric Arc Furnace
A key feature of the project is its integration with POSCO's newly completed electric arc furnace (EAF) at Gwangyang. The 8CGL line will therefore serve as an important production base for lower-carbon automotive steel.
POSCO plans to install an ultra-high-temperature heat-treatment system specifically optimized for EAF-based steel. This is intended to enable the company to produce automotive-grade galvanized steel using lower-carbon inputs while maintaining the quality characteristics required by automakers.
PKX Deploys AI and Robotics to Boost Production Efficiency
8CGL is being designed as a highly automated production facility. POSCO plans to incorporate AI technologies based on more than 30 years of accumulated operating expertise.
AI systems will analyze material, process and quality data in real time and adjust equipment accordingly. The company expects this to help reduce quality variations and defects while improving production efficiency.
Robotics will also be used for higher-risk manufacturing activities. PKX specifically plans to apply AI and robotic technologies to tasks such as removing impurities from high-temperature molten zinc and collecting production samples.
Per POSCO, the investment is aimed at strengthening its future competitiveness amid rapid changes in the global steel industry. The POSCO-developed facility will specialize in automotive steel sheets and produce next-generation, high-quality products with improved cost and technological competitiveness. The facility is expected to further strengthen POSCO’s technological leadership in the global market.
