Pine stakes treated in autoclave using a vacuum-pressure system. The purpose of the treatment is to impregnate the wood with water-soluble salts to protect it from premature rot caused by fungi and insects, thus significantly extending its durability.

The stakes are manufactured with several finishes, all with sharp points and treated in autoclave:

- SQUARE SECTION with SHARP EDGES
- SQUARE SECTION with ROUNDED EDGES (planed edges)
- RUSTIC. Bark-stripped wood with very good mechanical resistance. Available diameters: 2.5/4 cm, 4/5 cm, 4/6 cm.
- TURNED / CYLINDRICAL. Circular section with diameters of 4 cm and 6 cm.
