Posco's operating profit hit record high in Q3 on strong demand.
Around 2.6 billion U.S. dollars, up more than 360-percent from the same period the previous year.
The highest amount since the firm was first founded in 1968.
Its sales in the third quarter also jumped almost 45-percent on-year, to reach about 17.2 billion dollars.
The South Korean steelmaker belive this is due to rising demand from automakers, shipbuilders and construction companies, as these industries recovered from the pandemic.
Other contributing factor includes the rise in prices of key products.
