  • R. Square Engineers — sole proprietorship (not a Pvt Ltd; no CIN), est. 1993
  • GSTIN: 24ACYPP4306J1Z6 (Gujarat; PAN-based on an individual, consistent with proprietorship)

1.2 What they make & where money comes from

  • Legacy: valves, pipe fittings, spools and fabricated piping for process industry.
  • Hexello (2025): honeycomb core for abradable seals in gas turbines and aero engines, in stainless steel, nickel superalloys (Hastelloy X, Inconel-type) and titanium. Products offered with pre-loaded braze filler tape, diffusion aluminide coating, and “ready for vacuum brazing” to backing strips. Welding tested to ASME Section IX and AWS D17.2 (resistance welding for aerospace).

Decision path (for Hexello itself): Nirdesh → Mahesh Patel. Not worth a pilot at current size.

1.5 Recent news & timing

  • 2025: Hexello honeycomb line commissioned; EN 9100 and ISO trio certified; IMS 2025 exhibitor.
  • Timing for a referral ask: good, as Nirdesh is visible and active in his network after the launch.

2. Energy profile

DISCOM: MGVCL (Madhya Gujarat Vij Company Ltd) — Vadodara city and GIDC Makarpura. Likely LT industrial or small HT connection [~].

2.1 Bill band

Working estimate: ₹0.5–3 lakh/month [~].

  • Resistance seam/spot welding for honeycomb foil is intermittent and low-kWh; foil forming presses are small.
  • Legacy fabrication (welding sets, cutting, small machining) adds a few tens of kW.
  • Vacuum brazing: the brief assumed vacuum brazing furnaces as the energy driver. Hexello’s own product pages say parts are supplied “ready for vacuum brazing” and with pre-loaded braze tape, which means the customer usually brazes [!]. If Hexello adds an in-house vacuum furnace later, a 100–300 kW furnace running batches could add ₹3–8 lakh/month [~].
  • Diffusion aluminide coating may be outsourced or done in a small furnace [!].

Fails the ₹30 lakh/month Band A gate by an order of magnitude.

2.2 Generation / renewables

Unknown. Gujarat rooftop solar is common in GIDC estates [~].

2.3 EnMS / ISO

ISO 14001 certified (environmental), not ISO 50001. No PAT, no BRSR.

2.4 Likely leak categories

Too small for Stamped’s ledger to pay back. If an in-house vacuum furnace arrives: furnace pump-down and holding, chiller, compressor.

3. Operations, equipment & digital stack

3.1 Process flow

Foil coil (Hastelloy/Inconel/SS/Ti) → corrugation/forming → resistance welding of nodes into honeycomb blocks → cutting/EDM or machining to shape → optional braze-tape loading / aluminide coating → inspection → dispatch to customer for brazing to backing rings.

4.2 Fit score rationale

4/10. Down from the brief’s MEDIUM. Size check fails on both revenue and bill. The score is held at 4 rather than 2 because Nirdesh’s ex-Vedanta and Flexatherm network around Vadodara/Anand/Halol is a credible referral source, and a verified email makes the ask easy.

4.3 Wedge

The strongest wedge is: a referral ask. Nirdesh’s network across Vadodara heavy industry (Vedanta-era operations colleagues, Flexatherm, GIDC Makarpura neighbours, Hexello’s turbine customers) can open one or two plant heads at forges, foundries or heat-treatment plants on MGVCL, where a 60-Day Proof is worth doing.

4.4 Objections

ObjectionResponse
”We’re too small for this.""Agreed, that’s why I’m asking for an introduction, not a pilot."
"I don’t want to push vendors on my network.""One name you’d be comfortable with. If they say no, that’s it.”

4.5 Pilot design

None for Hexello now. Revisit if an in-house vacuum furnace is installed.

4.7 Pitch sketches

  1. Referral (Nirdesh): “You know who runs the big furnaces around Vadodara. One introduction, and if it works I’ll make sure they know it came from you.”
  2. Future (Hexello): “If you bring vacuum brazing in-house, let’s meter it from day one. A furnace running half empty is where the money goes.”

5. Before you reach out

5.1 Discovery checklist

  • Does Hexello plan an in-house vacuum brazing furnace? Size and timeline?
  • Who does diffusion aluminide coating: in-house or outsourced?
  • Current MGVCL connection type (LT/HT) and monthly bill
  • Which Vadodara/Halol/Savli plants does Nirdesh know at plant-head level?
  • Any Vedanta ex-colleagues now running Gujarat plants?
  • Flexatherm’s own plant size and energy profile (possible prospect)
  • Hexello’s Gujarat suppliers and customers with furnaces or forging

5.2 Do not lead with

  • Do not lead with a pilot offer for Hexello; it’s too small and he’ll know it.
  • Do not lead with vacuum brazing as if they run furnaces; evidence says the customer brazes.
  • Do not lead with AI, ESG or solar.
  • Do not lead with “verified on the next MGVCL bill”; lead with verified with evidence on Stamped’s ledger.

6. Risks, flags, controversies & sources

6.1 Risks & controversies

  • Size check fails: micro/small proprietorship, bill far under the ₹30 lakh gate. This kit is a referral ask, nothing more.
  • Entity confusion: brief says “R. Square Engineers / Hexello”; there is no Pvt Ltd entity. Contracts would be with the proprietorship.
  • Controversy search: none found (searched: “R Square Engineers Vadodara”, “Hexello honeycomb”, “Mahesh Patel R Square Engineers” with lawsuit/penalty/GPCB/fraud). Nirdesh’s past employers (Vedanta) have public controversies unrelated to him or Hexello.

6.2 Data quality flags

  • Revenue from directories only [dir].
  • Vacuum brazing location [!]: inferred from product descriptions.
  • Atul Bhagat’s role unclear.
  • Phone numbers from directories, not the company site.
