Where the Money Is Going
Pesquería is Ternium’s industrial centre in Nuevo León, a state in northern Mexico. Its third phase adds US$4 billion and lifts cumulative investment there to more than US$7.5 billion, Mexico Industry reported on 28 April 2026.
Ternium’s own news page of 19 February 2024 called its June 2023 plan at Pesquería the biggest investment in its history, at US$3.2 billion. It said the complex would total US$6.8 billion once the third part was done, with slab capacity of 2.6 million tonnes a year.
Cold-rolling and galvanizing lines, which are finishing lines for steel sheet, started at the site in February 2026, Mexico Industry reported. It said the slab mill was then expected towards the end of 2026.
In its release of Tuesday 3 November 2026, Ternium said third-quarter capital spending of US$398 million went primarily to the slab mill, which it says is advancing according to plan. Nine-month capital spending reached US$1.24 billion.
In Plain English
Ternium is a steelmaker listed on the New York Stock Exchange under the symbol TX, with its main mills in Mexico. A slab mill is a plant that makes steel slabs, the raw form for flat steel.
USMCA is the US-Mexico-Canada trade pact, known as T-MEC in Spanish. Unfairly traded imports are steel sold abroad below a fair price, a practice often called dumping.

The Import Problem in Ternium’s Words
Máximo Vedoya, Ternium’s chief executive, spoke at the Steel Market Update Summit, a steel industry conference, in August 2025. He said the imbalance with China is destroying all manufacturing, not just the steel industry, according to a Ternium news page of 27 August 2025.
Vedoya said the answer is regional competitiveness under the USMCA, Mexico Industry reported on 29 August 2025. He added that Mexico applies more trade-defence measures than the United States, meaning more of the tools governments use against unfairly priced imports.
Vedoya also said Mexican steel is only 2% of US steel consumption, and Mexico Industry reported the same. Those claims are the chief executive’s own view, not our findings.
What Ternium Says It Is Winning
In Mexico, Ternium said in its release that shipments to the commercial market continued to rise, with higher volumes to industrial customers. It says it is “gaining market share by replacing imported steel in both the commercial and industrial markets”.
Ternium also expects data centres and gas pipelines to add to steel demand. Our report on its third-quarter earnings covers the company’s results in detail.
