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.
