We are honest about scope: every product is functionally tested unit-by-unit before it ships, powder-coat is sampled, and we expose finishes to water + sun. The heavy lifting on raw-material qualification is done by our suppliers — and we keep their certificates on file.
| What | How | Frequency |
|---|---|---|
| Functional check of every unit | Hand-operate the shutter / door / panel through its full motion. Verify lock engagement, roller travel, hinge action, gasket compression, drainage. | 100% — every single unit before packing |
| Powder-coat thickness | Electronic coating-thickness gauge — target 60–80 microns. Re-coat if below 50 µm. | Sampled — at least once per coating batch |
| Powder-coat adhesion | Cross-cut tape test (ISO 2409 style). Coating should not peel. | Sampled per coating batch |
| Water exposure (weathering) | Coated samples kept under continuous outdoor water spray on our factory roof — checked weekly for blistering or staining. | Ongoing — sampling per coating run |
| Sun exposure (UV / fade) | Coated samples kept under continuous direct outdoor sun on our factory roof — checked monthly against a reference panel for fade. | Ongoing — sampling per coating run |
| Visual + dimensional check | Mitre gaps, alignment, scratches, glass clarity, hardware fit — checked at packing. | 100% — every single unit before packing |
The two biggest material risks in an aluminium window — alloy quality and hardware durability — are not solved by a small factory's test bench. They are solved by buying from people who already prove it. That is what we do:
Every billet we receive is 6063 T6 (or T5 for selected systems) grade — the international standard for architectural aluminium extrusion. The mill issues a Mill Test Certificate (MTC) with each consignment, certifying alloy composition (Si, Mg, Fe), temper, and mechanical properties. We file the MTC against the project and share it on request.
We use polyester powders from Akzo Nobel, Jotun and Asian Paints PPG exclusively. Each batch comes with the manufacturer's Qualicoat-class certificate for the powder. We do not buy unbranded powder.
DGU units are pre-assembled by Saint-Gobain, AIS (Asahi) or Modi Guard with their own factory warranty papers. We do not assemble DGUs in-house — sealed-unit assembly is a specialised process best left to the glass major.
Locks, hinges, rollers, friction-stays, espagnolettes — all imported and branded (HOPPE, ROTO, SIEGENIA, GU, Yale and similar). These brands ship with their own factory cycle-test certification (typically 10,000–25,000 cycles). We do not modify or rebrand hardware.
A small to mid-size architectural-aluminium manufacturer in India has two realistic choices:
We have always done (2). The result is field-defect rates measured in tenths of a percent, repeat customers, and the ability to say "yes" when a customer asks for the actual paperwork. We send the supplier MTC, the powder Qualicoat certificate, the glass warranty and the hardware spec — not a self-issued report.
For B2B projects (commercial towers, builder developments, high-rises) where the developer's consultant requires an independent qualification report, we engage NABL-accredited external labs — typically NTH Mumbai, ICOMM Hyderabad or CBRI Roorkee — for project-specific testing.
The customer's consultant nominates the lab, the cost is billed at actuals on the invoice, the lab's original report is shared directly with the consultant, and our internal team supports the test setup. We have done this for high-rise commercial work on facades, structural glazing, and pergola wind-load.
Architects, builders and informed homeowners are welcome to ask for any of:
Email [email protected] with your quote number — we WhatsApp the PDFs within 24 hours.
No — we do not have an in-house wind-load chamber. We engineer to recognised system designs that have been wind-load qualified by the original system designer. For B2B projects that need a project-specific wind-load report, we commission a NABL-accredited third-party lab at the customer's cost.
A salt-spray chamber and the lab discipline to run it correctly is a serious capital + manpower investment that we honestly cannot do at our current scale. We instead rely on Qualicoat-class powder (Akzo Nobel / Jotun / Asian Paints PPG) whose own salt-spray certificates back the coating. For coastal projects we recommend Qualicoat Seaside Class powder.
6063 T6 for structural members and 6063 T5 for non-structural mullions / sashes — the international standard for architectural aluminium extrusion. The MTC from the mill is on file for every consignment and shared on request.
Because it is not our hardware — it is HOPPE, ROTO, SIEGENIA, GU or Yale (branded imported). Each of those brands ships their cycle-life certification with the product. We do not modify, re-brand or unbox-and-reassemble; you get the brand's own warranty.
Ask for: (1) the aluminium Mill Test Certificate, (2) the powder Qualicoat certificate for the colour batch, (3) the glass DGU warranty paper, (4) the hardware brand's cycle certificate. For a high-rise sanction you may additionally need a NABL-lab wind-load + water-tightness report — we coordinate that as a paid third-party test.
