GI Steel Tubular Poles
Galvanized Poles, Kolkata
Hot-dip galvanized swaged tubular poles for street lighting and power distribution, made in West Bengal for a long, low-maintenance service life.

GI Tubular Poles
Made to Last Outdoors
Subham Poles Projects Pvt. Ltd. is a GI tubular pole manufacturer in Kolkata. Our galvanized steel tubular poles are swaged poles that are hot-dip galvanized after fabrication, so a layer of zinc protects the steel on every surface, inside and out.
Zinc protects steel in two ways. It forms a barrier against moisture, and where the coating is scratched it corrodes first, sparing the steel underneath. That is why galvanized poles outlast painted poles in rain, humidity and coastal air, with little or no maintenance.
We make GI tubular poles to IS 2713 in the height, wall thickness and fittings your project specifies, for electricity distribution companies, municipalities, contractors and developers in Kolkata, West Bengal and across India.
Working to a tighter budget on an inland site? Compare with our MS steel tubular poles, which share the same structure with a painted finish.

The Advantages of
Galvanized Poles
Protection Inside and Out
Dipping the whole pole in zinc coats the inside of the tube too, where paint cannot reach.
Self-Protecting Coating
If the surface is scratched in transport or installation, the surrounding zinc still protects the exposed steel.
Low Maintenance
No repainting cycles, which matters for poles along busy roads and in hard-to-reach places.
Lower Lifetime Cost
A higher price at purchase is usually recovered through years without maintenance or early replacement.

How a Pole Is
Hot-Dip Galvanized
Fabrication
The tubular sections are cut, swaged and fitted with plates and brackets before any coating.
Surface Preparation
Degreasing, acid pickling and fluxing remove oil, scale and rust so the zinc bonds to clean steel.
Zinc Bath
The pole is dipped in molten zinc, which forms a bonded coating on every surface, inside and out.
Inspection and Dispatch
Coating, straightness and finish are checked before the poles are dispatched to site.
Where GI Tubular Poles
Make the Difference
Galvanized poles are the right choice wherever poles face moisture, pollution or salt air, or where maintenance is hard to arrange. In Kolkata's humid monsoon climate, that covers most outdoor sites.
Road Lighting
Highways and arterial roads, where poles must stand for decades with little maintenance.
Street Lighting
Municipal and panchayat street lighting schemes that need a long, low-upkeep service life.
Traffic Signal Mounting
Signal and signage poles at busy junctions, where repainting would mean disrupting traffic.
Industrial Estates
Factories, chemical plants and warehouses, where fumes and dust speed up corrosion.
Parking Areas
Open parking and vehicle yards exposed to rain, splash and run-off.
Commercial Spaces
Office campuses and retail developments that want a clean finish without repainting.
Parks & Walkways
Lakefronts, riversides and gardens, where poles stand in damp ground and humid air.
Residential Townships
Housing developments handing over street lighting to residents' associations or civic bodies.

Questions
Common questions from buyers about galvanized steel tubular poles.
What is a GI steel tubular pole?
It is a swaged steel tubular pole that has been hot-dip galvanized: dipped in molten zinc so a zinc coating bonds to the steel inside and out. The coating protects the pole from rust for far longer than paint alone.
Why choose a GI pole over an MS pole?
A GI pole costs more at the start but needs little or no maintenance for many years, while a painted MS pole needs periodic repainting. For coastal, humid or industrial sites, and for public infrastructure that must last, GI is usually the better value over the life of the pole.
Does a galvanized pole need painting?
No. The zinc coating protects the steel on its own. Where a colour is wanted, GI poles can also be painted or powder coated over the galvanizing for extra protection and appearance.
Which standard do your GI tubular poles follow?
The poles are made to IS 2713 for tubular steel poles and galvanized to the coating requirement in your tender or specification.
Are GI poles suitable for coastal areas like Digha?
Yes. Galvanized steel is the usual choice near the sea, where salt air corrodes painted steel quickly. Our galvanized poles are installed at the Jagannath Mandir in Digha.
Do you supply GI tubular poles across India?
Yes. We manufacture and galvanize in West Bengal and deliver to project sites across India.
