Concrete towers often offer logistical advantages over tubular steel towers. Large tower diameters can be realized because they are not limited by transport restrictions when the tower is erected piece by piece on site. The time required for assembly of the segments and the erection of the tower on site is a significant cost factor. We can minimize the construction period on site by employing smart concepts for the connection of the individual element. In addition, all the advantages we offer in the design of tubular steel towers take full effect for the upper steel sections of the concrete tower.
