If you’re finalising the roof drawing for a warehouse, logistics park, or factory shed anywhere across Mumbai, Navi Mumbai, Thane, Panvel, Bhiwandi, Kalyan, Taloja, Turbhe, Vashi, Uran, or the wider Raigad belt, there’s a decision that often gets left until the last minute – and shouldn’t be: what GI gutter are you using to carry that water away? On a large industrial roof, a poor gutter choice doesn’t just mean an occasional drip – it means concentrated water volume, during the Mumbai/Konkan monsoon, finding the weakest point in your drainage, fast.
Contractors and fabricators across this belt often call this item “panali” rather than “gutter” – if that’s the word you’ve been searching, you’re in the right place. We manufacture GI and PPGI gutters in-house at our Taloja MIDC plant, built to your exact site drawing, with delivery across Mumbai, Navi Mumbai, and neighbouring industrial areas.
Why a Big Roof Needs a Properly Specified Gutter
A warehouse or factory roof has a much larger catchment area than a house – meaning far more water arrives at the gutter, far faster, during a heavy monsoon downpour.
This matters especially for sheds and logistics parks around Taloja, Turbhe, Bhiwandi, and the Panvel–Uran industrial belt, where large PEB structures are common. Undersized, poorly made, or wrongly specified gutters on a structure this size don’t just leak – they can sag, detach, or overflow onto the building’s foundation and stored goods.
- Large catchment area: more roof area means more concentrated water volume at every gutter run.
- Monsoon intensity: Mumbai/Konkan rainfall arrives in sudden heavy bursts, not gradually.
- Consequence of failure: overflow can reach the building foundation and stored goods, not just the ground outside.
Getting the gutter spec right is a structural decision, not a finishing touch.
Metal Gutter vs. PVC Gutter – Which Should You Specify?
Both are genuine choices in the market, and the right answer depends on your project. Here’s an honest comparison, not just a sales pitch.
| Factor | Metal (GI/PPGI) | PVC |
|---|---|---|
| Sun & heat exposure | Dimensionally stable, no known UV brittleness failure mode | Well documented to become brittle and prone to cracking under prolonged UV/heat |
| Temperature swings | Far more dimensionally stable across seasons | Expands/contracts significantly; can warp or sag without perfect expansion joints |
| Heavy rain & debris load | Built for high water volume and debris weight at industrial thickness | Can struggle with heavy volume/debris weight – sags or pulls away from structure |
| Joints over long runs | Welded/formed runs, less joint-dependent | Relies on snap-fit or adhesive joints, which weaken over time – riskier on long runs |
| Total cost over building life | Higher upfront, typically lower lifetime cost | Cheaper upfront, but more frequent replacement/repair |
This is the big consideration for industrial roofs: a large catchment area creates exactly the heavy water volume and debris load scenario where metal, at the thicknesses we manufacture, is built to perform – and PVC’s failure modes become most likely.

What We Manufacture – Fully Customizable
We don’t work off a fixed catalogue. You choose the raw material, colour, coating, and design – built exactly to your site’s drawing and your structural consultant’s specification.
- PPGI (colour-coated), 0.50mm to 1.50mm: the common choice when the gutter needs to match your roofing sheet’s colour, using the same RAL shade.
- GI (plain galvanized), 0.60mm up to 3.00mm: for heavy-duty applications where load capacity matters more than colour-matching.
- Raw material: top-grade coil from JSW and AMNS.
Which one is right for your project genuinely depends on what your structural consultant or PEB drawing specifies – we build to that spec, in either material, across the full thickness range. We’re not steering you toward one option; we’re set up to deliver whichever your project calls for.
Standard Designs We Manufacture
Three profiles cover most projects – each fully customizable in size to your drawing. Every gutter is manufactured to your exact site dimensions, not a fixed size; the diagrams below are illustrative cross-sections only.
Figure 3: Box Gutter – stepped wall on one side for added strength, straight wall on the other. Our most-produced design.
Figure 4: Eave Gutter – angled flange to sit at the roof’s edge, with a stepped outlet side.
Figure 5: Valley Gutter – V-profile trough with flared top lips, for where two roof slopes meet.
We also manufacture matching end caps for both ends of the gutter run – this closes the channel off neatly, gives a finished look, and prevents water from simply running out the sides instead of down the outlet where it’s supposed to go.
How It’s Made
Every gutter is formed on our own state-of-the-art NC (numerically controlled) bending machine at Taloja MIDC – precision bending to your exact dimensions, not a generic stock size. Because it’s fully in-house, there’s no middleman and no dependency on someone else’s production schedule.
Dispatch Time
Standard dispatch is 2–3 working days from confirmed drawing and specification – since every gutter is custom-made to your site, not pulled from fixed-size shelf stock.

Conclusion
On a large industrial roof, the gutter is a structural decision, not a finishing touch. Metal outperforms PVC on the factors that matter most for a big catchment area – UV exposure, temperature swings, and heavy monsoon load – and since every gutter we make is custom-built to your drawing, there’s no compromise on fit. Confirm your material, thickness, and profile with your structural consultant, then send us the drawing.

What is a GI gutter, and what do contractors call it locally?
A GI gutter is a channel made from galvanized (or colour-coated galvanized) steel that carries rainwater off a roof to a downpipe or drain. Contractors and fabricators in this market commonly call it “panali.”
Should I choose a metal gutter or a PVC gutter?
Metal generally holds up better under UV/heat exposure, temperature swings, and heavy monsoon water volume – all real factors on a large industrial roof. PVC is cheaper upfront but typically needs replacing sooner. See the comparison above for the full picture.
What thickness range do you manufacture?
PPGI (colour-coated) from 0.50mm to 1.50mm, and plain GI from 0.60mm up to 3.00mm – the right choice depends on your structural consultant’s specification.
Can you match the gutter colour to my roofing sheet?
Yes – PPGI gutters can be made in the same RAL shade as your roofing sheet for a consistent finish.
Can you make custom sizes, or only standard sizes?
Every gutter we make is custom-built to your site drawing and dimensions – we don’t work off a fixed catalogue.
Do you supply end caps?
Yes – matching end caps are manufactured to close both ends of the gutter run neatly and prevent water running out the sides.
What’s your dispatch time?
Standard dispatch is 2–3 working days from confirmed drawing and specification.
What brands of raw material do you use?
Top-grade coil from JSW and AMNS.
