Large telecommunications towers create delivery problems. Their lower segments are spatial structures with dimensions exceeding several meters wide. Most telecommunications towers available on the market are hybrid structures, in the sense that the lower segments are assembled from single pipes on site, while the upper ones are welded. This solution allows to minimize space during delivery, but increases the price of the entire structure and the time required for installation. We encourage foldable structures - they allow for easy transfer to another location in the future, sale. Our experience shows that bolted towers do not show lower stiffness compared to their welded varieties.
