The first electric arc furnace was installed in 1960s together with one of the very first continuous casters in Italy at that time.
Innovation continued with the installation of a new continuous casting machine with a three-line rotating turret in 1989.

In 2000, a new 80-ton electric arc furnace was installed, followed by the state-of-the-art secondary metalurgy in 2007.

In 2011, I.R.O. introduces a new continuous casting machine for billet production and invests in the rolling mill to expand the range of high-quality steel products.

Today I.R.O. is a proud contributor to the rich industrial history of Odolo, manufacturing steel for construction, automotive, aerospace, infrastructure sectors.
