Techint is an Italian-Argentinian conglomerate founded in Milan in 1945 by Italian industrialist Agostino Rocca and headquartered in Milan (Italy) and Buenos Aires (Argentina). As of 2019 the Techint Group is composed of six main companies in the following areas of business: engineering, construction, steel, mining, oil & gas, industrial plants, healthcare. Techint, with its subsidiaries, is the largest steel making company in Argentina. Techint claims to be the world's largest manufacturer of seamless steel tubes, mainly used in the oil industry.[1]


Agostino Rocca, an executive at Ansaldo and later at Dalmine and Siac (steel and iron industries) founded Compagnia Tecnica Internazionale (Italian for "Technical International Company") in Milan in September 1945, but developed its main activity worldwide. The original company name was changed after to Techint, its abbreviated telex code.[1][2][3]

The company began providing engineering services to a growing number of clients in Latin America -to where Agostino Rocca had traveled after World War II- and Europe. Construction activities soon followed: the first major Techint Engineering and Construction (E&C) project was a network of large diameter pipelines in Argentina and Brazil.[3]

Awarded a contract to build a 1,600 km (1,000 mi) gas pipeline from Comodoro Rivadavia to Buenos Aires in 1949 by President Juan Perón, Techint became a leading government contractor during Perón's ambitious infrastructure program in Argentina. Creating subsidiaries in Brazil (1947), Chile (1951), and Mexico (1954), the company opened its first seamless steel tube plant in Campana, in 1954; in 1969, Techint's Ensenada plant became the only Argentine manufacturer of cold rolled steel.[1]

In the 1980s important projects were undertaken in Argentina, Brazil, Ecuador and Mexico, and the company diversified into new fields of activity, building the first nuclear facilities and offshore platforms.[1]

In the early 1990s Techint purchased a stake in Argentina's then-leading steel manufacturer, the state-owned SOMISA. A significant part of Techint's core manufacturing strength has since been concentrated in the San Nicolás-Villa Constitución oil-and-steel corridor, where the company is involved in the production of cold rolled steel. In those years, the Techint Group invested in oil and gas blocks in Argentina through exploration and production company Tecpetrol.

In Italy, the Techint Group entered the health services sector by building and managing Instituto Clinico Humanitas (ICH), a hospital and medical research institute near Milan. Tenaris, the company under which all the manufacturing and service activities in the steel pipe business are grouped today, went public at the end of 2002 quoting in the Buenos Aires, Mexico City and Milan stock exchanges, and its American Depositary Securities listed on the New York Stock Exchange.[1]

On August 23, 2005, the Techint group bought 99.3% of Mexican Hylsamex for US $2.2 billion.[4] In press release, Techint informed that the Mexican steel manufacturer, and its previous steel manufacturers Siderar (Argentina) and Sidor (Venezuela) would be under a new subsidiary called Ternium, headquartered in Luxembourg.[5]

On April 30, 2007, Ternium, a division of Techint, announced that it had entered into an agreement in which it expects to gain control of Grupo IMSA, a major player in the Mexican steel industry.[6]

The decision of Venezuelan President Hugo Chávez to nationalize Sidor came on the heels of a series of industrial disputes over the previous year.[7][8] Compensation of around US$1.97 billion was agreed for the nationalisation of Ternium's 60% stake in Sidor, with the former keeping a 10% stake in the company,[9] but frictions emerged with the Kirchner administration in Argentina over their reported refusal to raise objections to the nationalization with President Chávez.[10]

The Techint Group invested US$2.3 billion in its Argentine operations from 2003 to 2008,[10] and its local Siderca unit's steel output rose from 2.5 million tons in 2003[11] to 4.5 million in 2008.[1]

In 2016 the Techint Group entered the mining industry through the Tenova's acquisition of several companies operating in this field.

TodayTemplate:When, the Techint Group has a workforce of 51,200 permanent employees.[1]
