 Second and third blast furnaces were completed in the mid-1960s and early-1970s respectively; Linz-Donawitz process steelmaking converters were added in 1968 at a cost of 92 million Deutschmarks.A galvanising line called BREGAL (Bremer Galvanisierungs GmbH) was authorised in 1991, as a joint venture between Klöckner, Ägäis Stahlhandel and Rautaruukki.During the mid-1980s oversupply compounded a weakened economic situation (see Steel crisis) leading to financial problems for the company.
