Acquisition of Ruukki Building Systems successfully completed

Donges Group have successfully completed the acquisition of Ruukki Building Systems, a subsidiary of SSAB Group. The transaction was already signed in July 2019 and has now been successfully completed following the approval of the Finnish competition authorities on 30th April 2020.

This means that the Donges Group continues to grow and can build on the expertise of another strong entity. Ruukki Building Systems (RBS), based in Helsinki, Finland, is one of the leading suppliers of building systems solutions in Northern and Eastern Europe. The company specialises in design, manufacture and installation of steel building frames, envelopes and bridge structures. RBS operates four production facilities in Finland, Poland and Lithuania.

Normek, which has been part of the Donges group for about one year, and RBS will in future operate jointly under the new brand NORDEC. NORDEC recalls the Nordic roots of both companies and stands for competence in design, engineering and construction.

Donges Group is continuing to expand the product and service portfolio and will be able to offer even more comprehensive services from a single source.
