Poles are made of pine wood.
Impregnation is carried out using pressure-vacuum in two variants;
1. Salt impregnation by Wolmanit . The impregnation is performed using the Bethell process.
2. Creosote impregnation is made using the traditional Rüping process. During creosote impregnation process , the poles are heated to the temperature of 50 – 70°C during impregnation.
On request, we also secure our poles against biological corrosion, using aluminum tape coated with a preparation which protects the wood.

The advantages of using wooden poles ;
Wooden pine poles for years are used in the construction of telecommunication, recently more and more are used, the construction of overhead power lines. By using this type of poles supports many of their advantages such as:
- high resistance to crushing and distortion.
- highly elastic limit strength reaching breaking which is particularly advantageous when the wind load .
- resistance to changing weather conditions (after impregnation) .
Wooden poles are also easy to recycle.
Our poles come from sustainably managed forests.
