The foundation for today’s Gränges was laid in 1896 in Grängesberg.
Thereafter, several different industrial enterprises became part of the Group, including the Grängesberg mines, TGOJ rail business, Oxelösund ironworks and a shipping business. In 1969 the Group acquired Svenska Metallverken, which included an aluminium products business, an operation that would later evolve into Gränges and Sapa. In 1972 work began on the development and production of aluminium heat exchanger strips in Finspång.
After the Gränges Group was acquired by Electrolux in 1980 a number of structural changes were implemented resulting in the sale of most of Gränges’ businesses. What remained was the production of aluminium. A key milestone came in 1996, when Gränges established a global presence by opening a production plant in Shanghai.
In 2005 Sapa was acquired and delisted after Orkla of Norway made a bid for the company. At the time Sapa had two lines of business: rolled aluminium products and extruded aluminium profiles. In 2013 the rolled products business took back the name of Gränges and in 2014 Orkla decided to list Gränges on the Nasdaq Stockholm stock exchange.
