Located on the Paraná River about 230km northwest of Buenos Aires, the Ternium Siderar steel plant is the main production facility of Ternium, Argentina's largest flat and long steelmaker.[1]

The plant was originally developed by Sociedad Mixta Siderúrgica Argentina (SOMISA), an Argentine state steel company created in 1947; initial plans called for the SOMISA plant to produce an annual minimum of 300,000 tons of steel, gradually increasing to 1 million tpa.[2] Following a series of delays related to financing, the plant was officially inaugurated by Argentine president Arturo Frondizi in 1960.[3] In 1974, Somisa raised its raw steel production capacity to 2.5 million metric tons with the addition of a second blast furnace. Following the expansion, the plant's original product line of hot- and cold-rolled coils, sheets, and plates grew to include rods, rails, and structural steel.[4]

By 1990, the plant had become Argentina's leading steel producer, with 11,600 employees and a significant presence in the manufacture of finished goods. However, under the presidency of Carlos Menem, the workforce was reduced, and by December 1991, only 5,285 employees remained. At the same time, the company, which historically had performed well, began to record an operating deficit, accumulating a debt of about 500 million dollars in just two years. That loss was associated with the export of steel products at less than 10 percent of their real value. The government subsequently made moves to privatize SOMISA, offering "voluntary retirements" of workers and ultimately selling the company at 10% of its value.[5]

In 1992 SOMISA passed into the hands of a consortium led by the Italian-Argentine group Techint, accompanied by the Brazilian companies Usiminas and Companhia Vale do Río Doce and the Chilean company CAP. The company was subsequently renamed Aceros Paraná and Siderar SAIC before arriving at its current name, Ternium Argentina S.A.[6][7][8]
