Cut into conical shape<\/b><\/span>
\nThe trapezoid is formed into a cone shape using<\/span> a bending press equipped by automatic manipulators which are<\/span> numerically controlled.<\/span><\/p>\n

Welding<\/b><\/span>
\nThe edges of the truncated cone are joined longitudinally by automatic and manual welding procedures.<\/span> The welding is carried out in compliance with specific processing techniques (WPS) compliant with the UNI EN standards<\/span> ISO 15609-2 and adopting qualified procedures (WPAR) in compliance with UNI EN ISO 15614-1 standards.<\/span> All the welding employees<\/span> are qualified according to UNI EN 1418 and 287-1 standards and are supported and controlled by<\/span> supervision with international qualifications (International<\/span> Welding<\/span> Engineer).<\/span> In this regard, welding is subject to visual inspection (VT) performed by qualified personnel in compliance with the UNI EN 473 standard.<\/span><\/p>\n

Tolerances<\/b><\/span>
\nThe machining tolerances comply with the UNI EN 40-2 standard.<\/span><\/p>\n

Finishing<\/b><\/span>
\nOnce 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).<\/span><\/p>\n

Galvanizing<\/b><\/span>
\nThe internal and external surface protection is guaranteed by a hot galvanizing process carried out from its<\/span> immersion in a bath of molten zinc, after pickling aimed at eliminating any slag and impurities.<\/span> 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.<\/span> 239.<\/span>
\nFor aesthetic reasons aimed at favoring the insertion of the pole within the urban context or for the need to strengthen<\/span> the protection against corrosion, the pole, on request, can be painted.<\/span><\/p>\n

Materials<\/b><\/span>
\nThe<\/span> poles are made using steel sheet S235JR (Fe 360B) with mechanical characteristics that comply with the UNI EN 10025 standard.<\/span><\/p>\n

Testing<\/b><\/span>
\nEach 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.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"

The metal coil is flattened by a combined \u201cstraightening-flattening\u201d system, with edge trimming<\/span> to eliminate the oxidized and \/ or deformed parts, cut in length by a \u201cslitter\u201d and diagonally by a \u201croller cutters\u201d.<\/span><\/p>\n<\/div>\n
