On 14,000 m² of modern production space, more than 100 specialists — welders, machining mechanics and industrial mechanics — work at one of the most capable sites for steel construction and special machinery in Baden-Württemberg.
As a certified welding contractor according to DIN EN 1090 and EN ISO 3834-2, we combine welding, CNC heavy-part machining, shot blasting up to Sa 2.5, industrial coating according to EN ISO 12944, press braking, plate rolling and vibration stress relief under one roof — heavy parts up to 50 t, components up to 26 m in length.
