The poles for self-supporting wind towers are the most used structures for the supporting both small and medium size generators from 20 Kw to 250 Kw. Made of S355J2 steel and equipped with internal or external stairs and landings, they can be composed of several overlapping trunks, cylindrical or conical trunks, bolted by means of suitably dimensioned coupling flanges. After priming, the surface treatment is finished with polyurethane paints. All our wind tower poles are built according to European CE standards and provided with EN 1090 and ISO 3834 certification.
