The company Tesias manufactures wooden trellises and panels, ideal for supporting climbing plants and for dividing various sections of the garden or courtyard. The products are made in any desired size with impregnated wood for increased durability and lifespan, and are ISO certified.

The impregnation process involves placing the wood in specialized autoclaves filled with water and preservative. Under a pressure of 12 atmospheres for about 3 hours, the preservative penetrates the core of the wood, stabilizing its structure. This method ensures maximum durability by protecting the wood from microorganisms such as fungi, insects, and bacteria.
