1.1 Legal identity & structure
- R. Square Engineers — sole proprietorship (not a Pvt Ltd; no CIN), est. 1993
- GSTIN: 24ACYPP4306J1Z6 (Gujarat; PAN-based on an individual, consistent with proprietorship)
- Address: 904/10, GIDC Makarpura, Vadodara 390010
- Proprietor: Mahesh Patel (LinkedIn: owner since Dec 1994); directories also list Atul Bhagat
[!] - Brand: Hexello (honeycomb), website hexello.in; legacy site under rsquareeng.com domain
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).

- Market: turbine OEMs and MRO shops in India and abroad; exhibited at IMS 2025.
1.2a Scale, MSME status & revenue
| Field | Value | Confidence |
|---|---|---|
| Revenue | ₹2–5 Cr legacy turnover [dir]; Hexello may add ₹1–5 Cr in ramp-up [~] | Low |
| MSME class | Micro or Small | Medium |
| Employees | 10–20 [dir]; AeroLeads shows 14 | Low |
| Export share | Unknown; aerospace honeycomb is often export-led [~] | Low |
Revenue range (mandatory)
| FY | Basis | Figure | Source |
|---|---|---|---|
| Recent | Proprietorship, legacy business | ₹2–5 Cr turnover band | IndiaMART / Justdial-type directories [dir] |
| FY26 | Hexello addition | Not disclosed | — |
| — | MCA | Not applicable (proprietorship) | — |
Working revenue range: ₹2–10 Cr [~]. Confidence: low. The brief’s “MEDIUM pending size check” fails the size check: this is micro/small.
1.3 Plants & footprint
| Site | Address | Role |
|---|---|---|
| GIDC Makarpura | 904/10, GIDC Makarpura, Vadodara 390010 | Single site: fabrication + honeycomb forming and resistance welding |
Shed size not public; a typical Makarpura GIDC plot is 500–2,000 sqm [~].
1.4 Leadership & champion map
| Type | Name | Role | Why | ||
|---|---|---|---|---|---|
| Connection / commercial | Nirdesh Sinha | Business Head | https://www.linkedin.com/in/nirdesh-sinha-1665827 | nirdesh.sinha@rsquareeng.com (verified) | Referral bridge |
| P&L | Mahesh Patel | Proprietor | https://www.linkedin.com/in/mahesh-patel-ba477930 | unknown | Signs anything |

| Maintenance / E&I | name TBD | Likely owner + an electrician | — | — | — |
| Production | name TBD | Honeycomb line supervisor | — | — | — |
| Generic | — | Sales | — | sales@rsquareeng.com | Fallback |
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.
3.1a Machine inventory
| Class | Present? | Count / size | OEM | Notes |
|---|---|---|---|---|
| CNC turning / lathe | Likely (legacy) [~] | unknown | — | Valve/fitting work |
| VMC / HMC | Possible [~] | unknown | — | — |
| HPDC / LPDC / GDC | No | — | — | — |
| Forge | No | — | — | — |
| Heat treatment | Vacuum brazing not evidenced in-house [!] | — | — | Parts sold “ready for vacuum brazing” |
| Press / stamping | Small forming presses for foil [~] | unknown | — | — |
| Resistance welding | Yes | unknown | — | AWS D17.2 |
| Wire/sinker EDM | Possible [~] | — | — | Honeycomb cutting |
| Compressors | Yes [~] | small | — | — |
3.2 Shifts
Likely 1 shift, ramping with Hexello orders [~].
3.3 Metering / digital
Unknown; probably the DISCOM meter only.
4. Stamped Energy fit analysis
4.1 ICP scorecard
| Gate | Result |
|---|---|
| Bill ≥ ₹30L/month | Fail (₹0.5–3L [~]) |
| Revenue ₹300–5,000 Cr | Fail (₹2–10 Cr [~]) |
| Vertical | Pass (precision metal / aerospace) |
| Connection quality | Good — senior operator with a heavy-industry network |
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
| Objection | Response |
|---|---|
| ”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.
4.6 Concern scores (1–10)
| Concern | Score | Who | Why |
|---|---|---|---|
| Energy / electricity bill | 2 | Mahesh Patel | Small bill |
| Maintenance / uptime | 4 | Owner | Few machines |
| Production / OEE / dispatch | 7 | Nirdesh | Ramp-up of certified aerospace line |
| Overall efficiency | 5 | Nirdesh | Early-stage business |
4.7 Pitch sketches
- 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.”
- 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.
