Services
We machine, treat and fire-retard wood
At the production plant we machine, treat and finish wood for outdoor use and for interior decoration: beams, battens, board and panels. Autoclave treatment in use classes 3.1, 3.2 and 4, and fire-retardant treatment in our own plant.
The six services
The whole process, in a single plant
Machining
5-axis CNC and beam machining centre for pieces over 13 m. Angled cuts and milling without repositioning the piece.
- 5-AXIS CNC
- BEAMS OVER 13 M
Autoclave treatment
Copper salts using the Bethell process: vacuum, pressure, vacuum. Treatment certificate per batch, on request.
- USE CLASSES 3 AND 4
- UNE-EN 335
Clear treatment
Protection and natural colour: for wood exposed to the weather that does not touch the ground or fresh water.
- USE CLASS 3
Fire-retardant treatment
In our own plant: in a pressurised varnishing booth or in the autoclave, also on pieces that have already been machined.
- OUR OWN PLANT
Brushing and texturing
Removes the soft parts of the wood and brings out its natural grain: relief and an aged look.
- SOLID WOOD · BEAMS · SLATS
Staining and finishes
Pressurised booth for wood stains, varnishes and paints, also after autoclave treatment.
- UV PROTECTION
The production plant
Tractia has a production centre of over 12,000 m², devoted entirely to working wood through all its stages. Its five areas follow the path of the wood.

On site. Pergola and structure kits drawn on a dimensioned drawing, with confirmed site measurements.
Machining carried out after treatment can impair it and leave points of attack in the wood. That is why we cut and machine before treating: this way we ensure that the product penetrates the entire surface of the wood evenly.
