Deacero breaks ground on mini-mill in northern Mexico

Written by Laura Miller


Mexican longs producer Deacero recently celebrated the start of the construction of its new $600-million mini-mill in Ramos Arizpe, Coahuila, in northern Mexico.

The new mill, dubbed the Ramos II Investment Project, will have an annual production capacity of 1 million tons of large structural profiles. Its location is near to Deacero’s existing Ramos Arizpe mini-mill which makes smaller sections.

Ramos II operations are expected to begin in February 2026, the company said in a statement on June 5.

Italy’s Danieli will supply the plant with an electric-arc furnace (EAF) and rolling mill for profiles up to 27 inches. The mill equipment supplier said this will be its fifth mini-mill installation for the Mexican steelmaker.

The mill will use digital technology to ensure the scrap fusion process does not affect Mexico’s electrical grid, the first use of this technology in Latin America, Deacero said.

Monterrey-based Deacero is Mexico’s largest longs steel producer, manufacturing a wide range of products, including rebar, wire rod, and structurals.

Leibowitz: Biden block of Nippon-USS deal has broad, mostly bad consequences

As one of my university professors once said (and it’s stuck with me for half a century), “Change is the only permanency.” On Friday, President Biden acted to block the acquisition of United States Steel by Nippon Steel Corp. of Japan, without acknowledging the changes that have already occurred in the steel industry, and which are likely to increase. After more than a year of raging debate, it seems that nobody was convinced by arguments. Nippon’s worker-centered concessions, including safeguarding the jobs of U.S. Steel’s unionized workers and committing to more than $2 billion in investments for the aging plants at Gary, Ind., and the Mon Valley complex in Pennsylvania, were not mentioned in the president’s announcement on Friday.
