Following the successful completion of the restructuring process and five completed add-on acquisitions – Kalzip, NORDEC, FDT and Norsilk – Donges is striving for further growth and consolidation of its very good positioning in the European market. The strategy’s pillars are the development of Northern European markets for bridge construction, the realization of synergies in the areas of building construction and buildings, and the use of existing sales channels in sales across the entire product portfolio.
