The story of Tenaris begins with the Techint Group, founded in 1945 by Agostino Rocca. The core of the company's beginnings can be traced to the establishment of Siderca in Argentina in 1948, which was the sole producer of seamless steel pipe products in the country at the time. Agostino Rocca was a key figure in the early development, overseeing the construction of Dálmine Safta in Campana, Argentina, in 1954. This was South America's first seamless steel pipe factory and the largest private steel plant in Argentina then.

Simultaneously, Techint was also building the production plant for Tamsa in Veracruz, Mexico, with operations at both facilities starting in 1954. Techint held ownership in both Siderca and Tamsa, managing the Siderca facility. While the exact initial equity splits for the founders are not available in public records, the Techint Group, controlled by San Faustin S.A., which is in turn controlled by Rocca & Partners Stichting Administratiekantoor Aandelen San Faustin, established the fundamental ownership.

The early ownership structure reveals that Tamsa became publicly listed on the Bolsa Mexicana de Valores in 1953, and Siderca followed on the Bolsa de Comercio de Buenos Aires in 1958. This indicates an early move toward public participation in these foundational entities. This early listing provided opportunities for external investors to become involved in the Tenaris ownership and the growth of the company.
