Altos Hornos de Mexico, S.A.B. de C.V. (AHMSA) is the largest integrated steel plant in Mexico. It has corporate offices in Monclova, Coahuila, in the center of the Mexican state of Coahuila, 155 miles from the United States border. History Teódulo Flores Calderon donated the land to AHMSA, later Harold Rudolph Pape founded Altos Hornos de Mexico in 1942 in Monclova, Coahuila for its proximity to the border, with the mines of iron located in the same state and Chihuahua, as well as with coal, located in the carboniferous region of Coahuila. Between 1944 and 1948, the production increased from 40,000 to 100,000 tons of liquid steel per year. In 1960, the smelter increased its capacity to 2 million tons of liquid steel per year, with this being consolidated as the largest company industry in Latin America. Throughout the decade of the '70s and after several expansions, the company achieved production of 3.75 million tons per year. In the decade of the '80s, AHMSA was nationalized by the federal government and went through several crises. In 1991, AHMSA was privatized and acquired by GAN (North Steeler Group). In 2005, the company began an upturn in production. Alonso Ancira, the owner and president of Altos Hornos, was arrested by the Interpol in connection with the 2014 sale of a fertilizer plant to PEMEX, the Mexican-state oil company, on May 28, 2019. The bank accounts of Altos Hornos and Emilio Lozoya Austin, the former CEO of PEMEX, were frozen 24 hours earlier. According to bank records he is bankrupted and has billions in debt. Alonso Ancira and other family members have been charged for corruption, money laundering, fraud and other crimes. It is believed that Lozoya will soon be arrested. Activity Ahmsa’s main steelmaking facilities and corporate offices are located in Monclova, Coahuila, close to transportation lines, raw materials supplies, principal points of export, and the company’s major domestic markets. Primary resources Two steel plants operate in an area of nearly 3,000 acres. AHMSA extracts coal and iron ore. The company has its own coal mines in Palau, located 70 miles from Monclova. Once extracted, the washed coal is shipped by railroad to AHMSA’s coke plants. The main source of iron ore is located in Hercules, Coahuila, a mine owned by AHMSA. From that point the iron ore is transported to AHMSA through a 180-mile pipe (called Ferroduct) that crosses the Coahuila
