(electrical resistance welded) according to UNI 7091\/72 standards. The tube is rolled at a temperature of 700\u00b0 C and the processing, entirely under numerical control, is aimed at increasing the mechanical characteristics of the steel.<\/p>\n<\/div><\/div><\/div> The process of rolling allows to obtain a product aesthetically very valuable as it does not have external welding; the surface of the pole appears to the view perfectly uniform.<\/p>\n<\/div><\/div><\/div> The steel used and the increase in thickness due to hot working (from the base to the top) give the pole superior performance. The manufacturing tolerances are in accordance with EN 40-2.<\/p>\n<\/div><\/div><\/div> After rolling, the pole undergoes specific machining operations at the base (e.g. slots) and tip (e.g. calibration).<\/p>\n<\/div><\/div><\/div> Surface protection, both internal and external, is ensured by means of a hot-dip galvanizing process, carried out by immersion in molten zinc bath, after pickling in order to eliminate any waste and impurities. The galvanizing process shall be carried out in accordance with EN ISO 1461 or, on request, in accordance with IEC 7-6 file No 239.<\/p>\n<\/div><\/div><\/div> The poles are made using standard steel pipes S275JR (Fe 430B) with mechanical characteristics in accordance with EN 10025.<\/p>\n<\/div><\/div><\/div> Every processing step is constantly monitored by the staff working under the supervision of the Department Manager who is directly responsible to the quality control department.<\/p>\n<\/div><\/div><\/div> The sheet metal purchased is processed through a plasma cutting plant to obtain the semi-finished trapezoidal shape required for the construction of the pole.<\/p>\n<\/div><\/div><\/div> The trapeze is formed into a truncated cone using folding presses served by numerically controlled automatic manipulators.<\/p>\n <\/p>\n<\/div><\/div><\/div> The flaps of the trunk of cone are joined longitudinally by means of longitudinal welding to plasma, autogenous welding, without the use of filler materials such as wire and flow, with the absence of process residues, and without visible welding, with penetration to 70-80% of the thickness. Welding is carried out in accordance with the technical specifications for machining (WPS) in accordance with ISO 15609-2 and using qualified procedures (WPAR) in accordance with ISO 15614-1. All welding personnel are qualified according to UNI EN 1418 and 287-1 and are supported and supervised by an international Welding Engineer (internationally qualified) supervision. In this respect, the welding is subject to visual inspection (VT) carried out by qualified personnel in accordance with EN 473.<\/p>\n<\/div><\/div><\/div> After welding, the pole undergoes specific machining at the base (e.g., slots) and tip (e.g., calibration).<\/p>\n<\/div><\/div><\/div> After welding, the pole undergoes specific machining at the base (e.g., slots) and tip (e.g., calibration).<\/p>\n<\/div><\/div><\/div> Surface protection, both internal and external, is ensured by means of a hot-dip galvanizing process, carried out by immersion in a molten zinc bath, after pickling in order to eliminate any waste and impurities.

For aesthetic reasons to favor the insertion of the pole within the urban context or the need to strengthen the protection against the action of the atmospheric agents, the pole can, on request, be subjected to a painting cycle.<\/p>\n<\/div><\/div><\/div> The poles are made using steel sheet S235JR (Fe 360B) with mechanical characteristics in accordance with EN 10025.<\/p>\n<\/div><\/div><\/div>![](\"http:\/\/www.siderpali.net\/wp-content\/uploads\/2023\/03\/pali-illuminazione-2.webp\" "\\"pali")
