Rio de Janeiro, 26 (Agência Brasil - ABr) - The Tubarão steel mill (Companhia Siderúrgica de Tubarão - CST), had Q4 net profits of R$113 million (US$47.2 million) in 2001, mainly due to the rise of the real against the dollar. With that result, the firm had losses of only R$70 million (US$29.3 million) for the year, in spite of falling demand and difficulties on international markets. The mill operated at full capacity, selling 4.7 million tons of steel plate (Tubarão is the world's biggest producer of plate steel), 93% of production was exported, 44% to the United States. (AB)
