First extrusion press. Further investments follow each other in rapid succession:

  • casting aluminium billets,
  • machines for aluminium tubes, 
  • a cold rolling mill for the production of aluminium strip.


Thanks to the success of the aluminium, the steel production did not survive and the company became the property of the Flemish government (GIMV)


  • A group of investors, under the direction of the industrial Aimé Desimpel, takes over the activities and places them in a new corporate structure: extrusion (profiles), pipes (welded tubes), RC system (architectural systems).
  • The ambitions of the new owners lead to large investments and acquisitions, through which Remi Claeys Aluminium grows up to an international group.
  • A series of important events happen during this period, among other things, the installation of a new 5500T press and the modernisation of the 2200T press.
