Steel construction with the precision of mechanical engineering. Design, engineering, manufacturing and installation – all from a single source and from our own certified production.
Each of our divisions benefits from the know-how of the other: complex welds in machine building are our daily business, and we mill precise stiffener plates for steel structures in-house.

Welding fixtures, presses, mixers, gantry robots and handling systems – from concept to acceptance with CE documentation.
