The metal coil is flattened by a combined “straightening-flattening” system, with edge trimming to eliminate the oxidized and / or deformed parts, cut in length by a “slitter” and diagonally by a “roller cutters”.

Cut into conical shape
The trapezoid is formed into a cone shape using a bending press equipped by automatic manipulators which are numerically controlled.
The edges of the truncated cone are joined longitudinally by automatic and manual welding procedures. The welding is carried out in compliance with specific processing techniques (WPS) compliant with the UNI EN standards ISO 15609-2 and adopting qualified procedures (WPAR) in compliance with UNI EN ISO 15614-1 standards. All the welding employees are qualified according to UNI EN 1418 and 287-1 standards and are supported and controlled by supervision with international qualifications (International Welding Engineer). In this regard, welding is subject to visual inspection (VT) performed by qualified personnel in compliance with the UNI EN 473 standard.
The machining tolerances comply with the UNI EN 40-2 standard.
Once the lamination phase is completed, the pole is subjected to specific operations at the base (i.e. slots) and at the tip (i.e. calibration).
The internal and external surface protection is guaranteed by a hot galvanizing process carried out from its immersion in a bath of molten zinc, after pickling aimed at eliminating any slag and impurities. The galvanizing process is manufactured in compliance with the UNI EN ISO 1461 standard or, upon request, in compliance with the CEI 7-6 standard dossier n. 239.
For aesthetic reasons aimed at favoring the insertion of the pole within the urban context or for the need to strengthen the protection against corrosion, the pole, on request, can be painted.
The poles are made using steel sheet S235JR (Fe 360B) with mechanical characteristics that comply with the UNI EN 10025 standard.
Each processing phase is subject to constant monitoring by employees who work under the supervision of the department head, who reports directly to the Quality Control Office.
