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.
