ArcelorMittal México will raise its annual steel production from between 3.6 and 3.7 million tons to 5.3 million in 2029, backed by a 180 million dollar investment in a new concentrator plant in Las Truchas, according to the plan its CEO, Víctor Cairo, presented and that Milenio reported on October 13, 2026.
The plan rests on a reorganization into three operating divisions: mining, long products and flat products. The new Las Truchas concentrator plant, scheduled to come online between June and July 2027, is meant to secure the ore that feeds that expansion, and the announcement comes weeks before the Lázaro Cárdenas steelworks marks 50 years on November 4, according to El Cronista. For Mexico the figure matters because steel is an input for construction and the automotive industry, and because installed capacity defines how much domestic demand can be served. In that market, Cairo points to China's overcapacity and the review of trade protection mechanisms across various economies as reference points.
The plan's numbers are concrete. Long product output will rise from one million to 1.5 million tons; the electric steel shop is working to eliminate bottlenecks and expand continuous casting capacity, and the arrival of new cranes points to capacity of up to 3.8 million tons and 2.5 million tons of hot-rolled coil. Cairo acknowledged that the previous two years were challenging, because of the 2024 strike and work on critical equipment, and summed up the priority this way: "Things happen, you have to turn the page and keep going."
The calendar is marked by two dates: November 4, when the Lázaro Cárdenas plant turns 50, and the startup of the concentrator between June and July 2027. The 5.3 million ton target for 2029 will be the indicator by which it is measured whether the recovered capacity translates into supply for Mexican industry.
