It was a new phenomenon to run forge mills separate from mining and pig iron production sites in Bergslagen.

This restructuring process appears to have been driven by the need to secure access to hydropower and timber for the forges since both the mines and blast furnaces used up considerable amounts of resources in the production of pig iron.

It formed the basis for a new Swedish industry that was located in Södertälje under the name of Vagnfabriks-Aktiebolaget i Södertelge (renamed in 1906 to Vabis that later merged with Scania AB).

Today, the mills in Virsbo, Ramnäs and Surahammar have been transformed into modern industries with international owners.

Industry in Surahammar includes: The Strömsholm Canal has been restored and is a popular route for small yachts.
