High Mast Lighting Pole

The high mast shaft is in polygonal shape, continuously tapered sections having dimensions and thickness as required in the design made from high tensile steel confirming to BSEN 10025 Grade S 355. The plate is plasma cut and folded to form polygon of required shape and then welded along longitudinal seams. The section lengths are typically designed and are such that transverse welding is not required. The partial penetration welds done through GMAW and SAW are proven over a period of time in masts of all heights and for all applications. The taper fit friction joints are assembled at site with equipment's usually available at construction sites and site fabrication work is not required during assembly. The overlap required is 1.5 times the diameter at the joint. The edge of the door opening is reinforced to guard against buckling and is provided with vandal resistant locking device. The shaft is attached to the flange using full strength buttwelds with supplementary gussets provided between bolt holes.
