Every section here is taken from the roll-forming line that produces it — machine geometry, not illustration.

Govardhan Shield

Formed on a YX 32-200-1200(1525) line at 28 roller stations.

32 mm RIB · 200 mm PITCH · PAN STIFFENER · 1000 / 1200 mm COVER

Each pan carries a stiffening flute between the major ribs. It adds nothing to cover width and little to weight, but it is what keeps a wide flat pan from oil-canning across the span — and it is why the developed width is 244.7 mm per pitch rather than 240.7 mm.

Vrindavan Tile

Formed on a YX30-163-978 line at 22 roller stations, with a four-post hydraulic press producing the transverse step.

Step tile is profiled in two directions — rounded ribs across the width and a transverse step down the slope. The step is what gives the sheet the shadow line of a laid tile roof; the rounded rib is what distinguishes it from a trapezoidal profile at a glance.

Mathura Steel

Formed on an automatic C-Z line at 21 roller stations, with electrically changeable sizing and hole punching after forming.

C SECTION · WEB 100–300 · FLANGE 40–80 · LIP 20 · 26×18 PUNCHING

Web depth and flange width are set from the control panel rather than by changing tooling, so a project needing C150, C200 and C250 is one setup rather than three. Bolt holes are punched in line after forming, which is what removes drilling from the fabricator's shop.

Dwarka Seam

Formed on a YX65 line at 14 stations, with a companion concave/convex curving machine holding 20 radii.

65 mm SEAM · 400 mm COVER · NO PENETRATION THROUGH THE PANEL

The female leg folds over the male, so the fixing clip sits under the seam and nothing penetrates the panel. That is what makes standing seam the specification for rooftop solar and for roofs that must not be drilled — and the taper facility takes a panel from 200 mm at one end to 600 mm at the other for conical and fan-shaped roofs.

Bhoomi Deck 65

Formed on a 42-station line — the highest roll count in the plant — from galvanized coil at 0.60 to 1.50 mm.

65 mm DEEP · 240 mm PITCH · 720 mm COVER · CROWN AND VALLEY KEYS

Composite action comes from the keys, not from friction. The crown key is wider at the top than at its base, so once the slab cures the concrete cannot lift off it; the valley key does the same in the soffit. That re-entrant geometry is what lets the deck be counted as tensile reinforcement rather than as permanent shuttering.

Accessories are the part of a roof most often sourced separately, arriving in a different batch of paint and a fortnight late. Made here from the same coil as the sheet, they match — and because the machine slits as well as folds, the girth is set to the drawing rather than to a stock size.

Two substrate tiers

Because AVMY forms rather than coats, the substrate is chosen for the job — not by whatever a single coating line happens to produce.

Standard

Galvalume & PPGI

Urban and semi-industrial exposure. The working specification for most industrial roofing.

  • AZ150 / AZ70 Galvalume, PPGI Z80 – Z275
  • SMP and PVDF paint systems
  • 10 – 15 year perforation warranty
  • SRI > 70 options for green-rated projects

Premium

Optigal® ZAM

Zinc-aluminium-magnesium. Specified where corrosion, not appearance, governs the decision.

  • Optigal® Prime and Pinnacle, ZM80 – ZM120
  • Roughly 3× cut-edge protection
  • 15 – 25 year substrate warranty
  • Coastal C5-M, heavy industrial, high UV
  • No hexavalent chromium — green building compliant

What the plant does

Eight machines, one shift, one despatch schedule. Range is why they are all here.

36,354MT per annum

Installed capacity across six production machines, single shift, derated for real changeover and setting time.

6 msingle-piece folding

CNC bending to 125° across colour-matched accessory work — the flashings arrive with the sheet, not a fortnight later.

On sitestanding seam forming

The seam machine travels to the project. No panel length limit, no transport creasing on long runs.

4.0 mmstructural capability

Z and C purlins from 1.5 to 4.0 mm, so secondary structure and envelope come from one supplier.

15 daysquotation validity

Coil is 90% of the price of a roof. Short validity is how the number you are quoted stays the number you pay.

1 dayto the coil mills

Pune, Vasind and Khopoli are all within a day's freight. Replenishment is short and stock risk stays low.

Your drawings stay yours

We use AI to draw sections, read take-offs and draft documentation. Three commitments follow from that.

01
Nothing of yours goes into a public tool
Your drawings, your pricing and anything under a confidentiality obligation go only into approved tools with a written data position — never a personal account, never a free consumer service.
02
A person signs
No quotation, no test certificate, no delivery commitment leaves this company on a machine’s authority. AI may draft it. A named person approves it and carries the consequence.
03
You can opt out entirely
If you would rather your drawings were not processed through AI tooling at all, say so once. We record it against your account and it holds for every order after that.

Every profile section and isometric on this page was drawn this way, from the machine suppliers’ own drawings. Where a dimension was not stated in the source it is marked indicative rather than guessed. Our full AI policy is a Board-approved document and we will send it to you on request.

Send us a spec

Profile, gauge, substrate and quantity is enough to price. If you have a drawing or BOQ, better still.
