Octagonal pole

Material used are based on the following standards

Octagonal Poles : HT Steel Conforming to grade S355JO or equivalent

 Base Plate : Fe 410 conforming to IS 226/IS 2062

Foundation Bolts : E.N.B. grade

Design :

The Octagonal Poles are designed to withstand maximum wind speed as

specified in IS875. The top loading area and the weight of fixtures are

considered while calculating the maximum deflection of the pole and to meet

the requirement of BS : 5649 Part VI 1982.

Pole Shaft :

The Pole shafts have octagonal cross section and are continuously tapered with single longitudinal welding. There

are no circumferential welding. They are provided with rigid flange plate of suitable thickness with provision for

fixing 4 foundation bolts. This base plate is fillet welded to the pole shaft from inside and outside. The welding is

done by MMAW process.

Door opening :

The octagonal poles have a door of approximate 500 mm length at the elevation of 500 mm from the Base plate.

The door is vandal resistant and weather proof to ensure safety of internal connections. The door is flush with the

exterior surface and has suitable locking arrangement. There is also a suitable arrangement for earthling. The poles

are adequately strengthened at the location of the door.

Welding :

Welding is carried out confirming to approved procedures duly qualified by third party inspection agency. The

welders are qualified for welding octagonal shafts.

Pole Section :

The Octagonal Poles are in single section (up to 9 meters) without any circumferential weld joint.

Galvanizing The poles are hot dip galvanized as per IS 2629 / IS 2633 / IS 4759 standards with average coating

thickness of 70 micron. The galvanizing is done by single dipping

Fixing Type :

The poles are hot dip galvanized as per IS 2629 / IS 2633 / IS 4759 standards with average coating thickness of

70 micron. The galvanizing is done by single dipping
