Shipbuilding steel phaj yog hais txog cov pa roj carbon thiab alloy steel phaj siv nyob rau hauv offshore thiab marine contructions, cov qib A, B, D, E, AH32/36/40, DH32/36/40, thiab EH32/36/40 uas ranged los ntawm txawv zog. Cov phaj feem ntau yog siv los tsim cov nkoj hulls, bulkheads, sab saum toj decks thiab hatch npog rau tankers, bulk carriers, thawv ships thiab LNG carriers.
