Our Story

OUR STORY

The history of the Engineered Reinforcing Steel Industries “ERSIGROUP” group is the story of an international success story that began in the 1960s, during what was known as the Spanish economic miracle. The development of our own construction system under the brand name Sistema Constructive Armatek® made us a reference for the construction sector, which has relied on our integral solution to build iconic infrastructures such as the Oresund Bridge -Denmark-, the Azores Viaduct -Portugal-, the Vidin Bridge -Bulgaria-, the Panama Canal or the subways of Guadalajara -Mexico-, Lima -Peru-, Dubai -Arab Emirates, or Riyadh -Saudi Arabia-

Our leadership is characterized by having managed to overcome each crisis with innovation
