Manufacture and process


  • The wood arrives in the form of logs or in bulk at the lumberyard. It is then transformed into chips (for particle board) or slats (for OSB).
  • The wood is dried and sorted to form the different layers of the panel.
  • It is then glued and placed on the continuous press line.
  • Pressing takes place at high pressure and temperature, in order to bake the panel.
  • A diagonal saw cuts the panels lengthwise.
  • The panels then pass into star coolers and are then cut widthwise before being stacked and stored.
  • The slab workshops make it possible to transform Particle Panels (PP) and OSB into slabs (with the shaping of grooves and tongues).
  • PP can be used as a support for melamine decorative panels.
  • The presses in the melamine workshop allow the decorative paper to be glued to the rough particle board.
  • Each panel is visually inspected before stacking, automatic strapping and placing in stock for shipment.
  • Some melamine panels can be transformed in the shelf workshop.


After being debarked, cut, dried and sorted, the slats pass through the gluing machines, where they are sprayed with formaldehyde-free glue. The forming machines form a “mat” (called mattress or cake) on a conveyor belt:

  • the 1st and the last forming machines form the outer layers and are equipped with guides, so that the slats are in the long direction of the panel.
  • the other 2 form the inner layer of the panel.

The mat is pressed at 250°C with a pressure of 300 bar. This process allows the panel to bake and gives it all its technical characteristics. Panels are cut continuously by 2 diagonal saws. They pass into star coolers, to be cooled then cut, stacked, strapped and put in stock, for shipping. 2/3 of the production is machined into slabs: tongues and grooves are added. The panels are used in construction: walls, roofing, floors, wooden frame houses, but also in packaging and increasingly in interior design.
