Foshan · Buyer-side team

The same series looks identical in every showroom. The money sits where you cannot see it.

One wire, one gasket, one hardware brand — same looking window, two different grades. Wall thickness, thermal break, gaskets, hardware, glass build-up. None of it shows in a photo, and all of it is in the price. Two quotes can carry the same series name and still be far apart, and nothing on the paperwork tells you which one you are buying.

That is why comparing quotes in this trade fails: the price sits on the series name, not on the parts. So the only thing that works is reading it off the components — and then checking that the components are what actually ships.

How we take it on

We write your specification part by part, then hold the factory to it from the sealed sample to the loaded container.

  1. Sealing first Samples are sealed before the order and before any payment — one set held by you, one held in Foshan, both signed and dated. The sealed sample, not the drawing, is the reference. The first unit off the line goes next to it before the run continues.
  2. One specification, one quote form Every candidate quotes the same part-by-part sheet: profile series and wall thickness measured on the profile, glass build-up (thicknesses, coating, spacer, gas), hardware brand and model, finish system and class, screens and accessories, sizes, quantities, and what is excluded. A supplier who will not name a part by brand and model is telling you something. The shortlist names the factories dropped, and why.
  3. The numbers, checked at the source An NFRC U-factor is a whole-product rating — frame, glass, spacer and sash together, at the size listed. A glass center-of-glass value is a different number, and always the better-looking one. The product line and the configuration go back to the NFRC Certified Products Directory, by licensee name and label certificate number, and the values have to match the configuration you are buying. Test reports are read for method, laboratory and specimen size: a report is evidence for the specimen tested, and for nothing else.
  4. Counted at the container, not on the packing list Ordered, produced, loaded and invoiced — four numbers reconciled before the container leaves, while it is still open. The count is done by category at loading, and photographed, so what went in can still be checked weeks later. Packing is supervised in person: we are on the line while the goods are packed, so we see what goes into the carton — not only what is counted at the container door.
  5. Drift caught by measuring If a part is re-sourced before or during production, you approve it in writing first — a sample photo is not an approval. Every later batch is measured against the sealed sample and the locked specification, not against what the factory says it built.

Who you are dealing with

One rule behind all of the above: every report carries its basis and the original photos from the site — hand it to anyone you like and have it checked.

Recommendations

We do not recommend factories, and we do not represent any of them.

What you get instead is a comparison you can act on. Ask us, and we will put a shortlist side by side against one specification — profile series and wall thickness, thermal break, glass build-up, hardware model, finish, and terms — so that the differences are visible. Which one you choose is yours to make.

A recommendation is only worth something if the person making it has nothing to gain from it. We take no commission from any factory, and your payment never passes through us.

Which of these is the one costing you?

Send the one that is yours — a drawing, a spec sheet, a quote you do not trust, or just the question. I answer within 24 hours; if you write while Foshan is asleep, the answer is waiting when we wake up.
