In 1978 it acquired two production lines for the tubes manufacturing, in order to diversify its main activity: design, build and assembly of structural steelworks. At present the plant based in Aigle is specialised in the production of welded stainless steel and welded stainless steel re-drawn precision tubes. The welded tubes are destined to be used in the most critical areas of fundamental plants such as conventional and nuclear power stations, petroleum refineries, chemical and petrochemical plants and sugar mills.
