Soenderjyllands Maskinfabrik (SM) was founded in the end of the 1940s and was owned by the utility, Soenderjyllands Hoejspaendingsvaerk, until 1998 (now Dong Energy). In the beginning, it was a service workshop for the utilities, with in-house production of steel constructions for use in power plants and production of transmission towers. Through the years, SM gained experience in other industries and developed competencies in material handling systems, process equipment, and complex steel structures for larger constructions.
DS Gruppen acquired Soenderjyllands Maskinfabrik in 1998 and named the company DS SM. At the time, DS Gruppen owned ABC Coating in Roedekro where the company handled coating of wind turbine towers for Micon (now Vestas). The acquisition enabled DS Gruppen to start black steel production of wind turbine towers. The first wind turbine tower production line was ready for use in 1998. Capacity was expanded with a second line in 2000 and a third in 2002. It also had close connections with the energy sector and continued to deliver steel constructions to utilities.
DS SM started selling to the oil & gas industry in Norway in the middle of the 1990s. Since then, the industry has grown and Norwegian-based companies have been acquired by global oil & gas suppliers, resulting in DS SM now supplying globally.
DS SM expanded its wind turbine tower production capacity in 2007 and 2008 with a state-of-the-art wind turbine tower coating facility based on fully-automated robot technology.
In 2007, two black steel production lines for towers with diameters of up to 6,5 meters were established.
In 2014 the company was acquired by Valmont Industries, Inc.
Today, the know-how and craftsmanship of Valmont SM combined with an advanced and highly automated production facility as well as a solid financial base, gives mutual benefits to both our customers and our collaborators.
