HES Trier was founded in 1990 as a production site for concrete pipes. Later the company Riewer used the premises for its steel trading and bending business. In 2007 the plant was taken over by the Sotralenz Group from Drulingen / France, which built new facilities for the production of reinforcing steel meshes and reinforcing steel in coils and bars. The company traded as Drahtwerk Horath, Werk Moselkai. In February 2017 the Trier plant was acquired by the RIVA Group and has traded since then as Hennigsdorfer Elektrostahlwerke GmbH, Werk Trier.
