Full description
In 1992 Brazilian manufacturer Gerdau acquired AZA assets and in 1999 began construction of a the modern mini-mill in Colina. At the same time, steel production at the Renca plant ceased and only the rolling mill remains in operation.
In 2018 Gerdau sells its entire stake in AZA to a consortium of four Chilean investors: Ingeniería e Inversiones Limitada, Inversiones Reyosan SpA, Los Andes S.A. de Inversiones, and Matco Cables SpA.
Today, AZA Acero Sostenable operates a profile rolling mill at Renca where billets are supplied by the Colina plant nearby.
