AutomotiveUltra-high strength
Giga Steel
Ultra-high-strength steel that lets carmakers build lighter, safer bodies — protecting passengers while extending EV range.
Product details →For more than half a century, POSCO has made the steel that builds nations. Now we are rebuilding how steel itself is made — replacing coal with hydrogen, and intuition with intelligence.
We were founded in 1968 to give a nation the steel it needed to rise. The next chapter asks something harder: to make that same strength without the carbon. We are turning fire into hydrogen, mills into intelligent systems, and a steelmaker into a materials company for the century ahead.
Founded in Pohang, Republic of Korea
Integrated steelworks at Pohang and Gwangyang
Annual capacity targeted for the HyREX demonstration plant
Target year for carbon-neutral steel production
From the car you drive to the grid that charges it. Tell us your industry and we'll point you to the steel built for it.

Every line has a virtual counterpart, letting engineers test changes, predict wear and plan maintenance before a single bolt is turned.
Vision systems and sensors catch defects as they form, so customers receive steel that meets spec the first time.
Smart energy management balances power across the works — the groundwork for a hydrogen-and-electricity future.
Steel is our core — and the foundation for an ecosystem spanning infrastructure, energy and the materials that power batteries.
World-class steelmaking and the specialist companies that keep it running.
Trade, energy, construction and logistics building a lower-carbon world.
Lithium, nickel, cathodes and anodes for the battery age.
