Originally known as Hylsa (an acronym for Hojalata y Lámina S.A.), the San Nicolás de los Garza steel plant was founded in June 1942 to make bottle caps for local beer company Cervecería Cuauhtémoc, which was unable to import sufficient steel during WWII. Production rapidly increased and diversifed throughout the 1940s, and by 1950 the plant was already supplying steel to 900 industrial clients in Mexico.[2]

By the late 1950s, shortages of scrap metal prompted the company to develop a new gas-based method for producing direct reduced iron (DRI). Known as the Hyl process, Hylsa's pioneering DRI technology was patented in 1957, and San Nicolás de los Garza became the world's first steel plant to adopt it for large-scale commercial use.[3][4]

In 1974, the Hylsa plant became the hub of the newly founded Alfa industrial group.[2] In 2005 Hylsa was sold to the Italian-Argentine conglomerate Techint, and in 2006 it was incorporated into the company's new Ternium division.[5]

By the mid-2010s, the plant was producing 2.4 million tons of raw steel[6] and 10.9 million tons of finished steel products annually and employing nearly 17,000 workers.[2]
