Fibreglass poles have a round or cone-shaped cross-section (dimensions depend on mechanical requirements).Compared with aluminium or steel poles they offer the following advantages:- lighter weight- less maintenance- surfaces are not attacked by corrosive agents- electrically insulated- less dangerous when impact occurs- extremely flexible in the wind.Certificated poles: These poles are recommended for small-size luminaires (decorative factor), in private areas, (anti-vandalism factor). They can be installed both on a base or buried according to measurements.
