Seit uber 50 Jahren bewahrt sich die SchweiBtechnik
Dusseldorf als verlSsslicher Partner im Stahlwerk.
MaBnahmen zur Verbesserung der Materialqualittt -
zum Beispiel durch Flammen, Schneiden,
Schleifen und die Reparatur von Stahlwerks-
zubehor durch SchweiBen - gehoren traditionell
zu den Tatigkeiten des Unternehmens.
Neuen Anforderungen im Stahlwerk und Struktur-
veranderungen stellt sich STD mit neuen Losungen und
vorausschauenden Ideen. Unsere Ingenieure und
Techniker entwickeln und konstruieren
Spezialanlagen, vor allem Brennmaschinen und Schleif-
manipulatoren jeder GrdBe und verschiedenster Bauart.
