Ternium Puebla steel plant (Planta Largos Ternium Puebla), also known as Hylsamex Puebla (predecessor), is a steel plant in San Miguel Xoxtla, Puebla, Mexico that operates electric arc furnace (EAF) and direct reduced iron (DRI) technology.

Background

The Puebla steel plant was founded in 1969 by Mexican company Hylsa (Hojalata y Lámina S.A.).

In the late 1950s, Hylsa, which had begun making steel at its San Nicolás de los Garza steel plant near Monterrey in the 1940s, pioneered a new gas-based method for creating direct reduced iron (DRI). The company's groundbreaking DRI technology, known as the HyL process, was soon patented, and the Puebla plant became one of the first in the world to use it commercially.

In 1974, Hylsa became the core member of the newly founded Alfa industrial group. In 2005 the company was sold to the Italian-Argentine conglomerate Techint and incorporated into Techint's new Ternium division.

Today the Ternium Puebla plant specializes in production of long steel products including rebar, wire rod and round bar for the construction, industrial and automotive sectors. Recent developments at the plant include the September 2019 installation of a new bag filter system to capture fumes and dust in the electric arc furnace.
