Ternium confirms Pesquería for its new Mexico slab mill

Steel producer Ternium will build and integrate into its existing downstream facility in Nuevo León state, Mexico, its new steel slab mill, the Luxembourg-based company said in a statement, citing growing opportunities from nearshoring.

In April, Ternium CEO Maximo Vedoya declined to reveal the exact mill location but said the final decision would be made soon. In February, the steelmaker announced plans to build a US$2.2bn and said its Pesquería unit in northern Mexico’s Nuevo León was one option.

The company expects construction to begin in December, with the start of operations anticipated during the first half of 2026. 

“The new state-of-the-art facility will complement the company’s new hot rolling mill in Pesquería, which began operations in mid-2021, as well as its downstream project at the same site, which is currently under construction,” the company said.  

“It will also be equipped with the latest technologies to accelerate Ternium's ongoing commitment to sustainability, including carbon capture capabilities and readiness to switch from natural gas to hydrogen use for DRI production. In addition, all water utilized in the new facility’s production process will be sourced from wastewater treated for industrial use,” Ternium added. 

In March, Tesla CEO Elon Musk confirmed the construction of the company’s fifth ‘gigafactory’ in Monterrey, Nuevo Leon, where the company expects to manufacture its next-generation electric vehicles. 

Ternium is Latin America’s leading flat steel producer, with operating facilities in Mexico, Brazil, Argentina, Colombia, the southern United States and Central America.
