Each tower of a LEITNER line is engineered, designed and manufactured according to the specific topographical and mechanical requirements of the project. The combination of the different tube diameters and wall thicknesses as well as the separation of the tower into individual sections can be modified as requested. As the tower height is manufactured to centimeter accuracy, customers are provided with the highest level of flexibility. At the same time, the best line profile with regard to the topographical conditions can always be achieved without having to adapt the excess length of the foundation. The use of standard tubes ensures rapid manufacturing and replacement.
