Batch ≠ sample
Cores get swapped between quotation and production: rock wool to EPS, 60 kg/m³ to 45. The specification is written into the quotation and checked again on the production run.
Inspection
How we inspect before it ships
The risk in China sourcing is not finding a supplier. It is receiving something that does not match the sample — a thinner panel, a different core, a batch that was packed badly. Here is exactly what we check, and what you get as evidence.
Three failures this prevents
Thickness shortfall
“0.5 mm steel” that measures 0.35 mm, or a floor board specified at 18 mm arriving at 15. We measure the run and photograph the reading, not the label.
Damage in transit
Bare-loading is how breakage goes from about 1% to 5–10%. Packaging is itemised on the quotation, photographed before loading, and never cut to win a price.
Five steps, in order
Step 1
Specification locked before we quote
Steel section, panel thickness, core material and density, floor build-up, door and window schedule. Written on the quotation — so you can see which of two price levels you are actually buying.
Step 2
Factory verified, not taken on trust
We work with a shortlist of partner factories that we visit and assess — workshop, production lines, capacity, and a business registration that matches the name on the paperwork. An office that presents itself as a factory gets screened out.
Step 3
First unit or sample approved
Before a batch runs, the first unit is assembled and photographed — the joint detail, the panel edges, the finish. You approve what will be repeated, not a render of it.
Step 4
Pre-shipment inspection, measured
On the actual production run: steel and panel thickness measured with the calliper in frame, core material checked, floor thickness verified, corner fittings and locks inspected, glass and hardware counted. Readings are photographed with a dated note in shot.
Measurement photographs are taken per order and sent to you with the inspection report. We do not publish a stock example, because a photograph of someone else's panel proves nothing about yours.
Step 5
Packing and loading verified
Wood frame, corner protectors and moisture barrier photographed as loaded. Each container is photographed during loading and before the doors close. The photographs below are from actual loading runs; per-order loading records are sent with your documents.
What you receive with every shipment
- Written specificationLocked before quoting, restated on the invoice
- Inspection photographsMeasured values in frame, dated
- Packing evidenceBefore and during loading
- Loading recordContainer photographed before the doors close
- DocumentationPacking list, invoice and shipping documents checked before release
What we do not claim
- Independent laboratory testingAvailable on request, at cost — not included by default
- Certificates we have not seenWe report what the factory can produce on paper, and verify it
- Zero riskInspection reduces the mismatch risk; it does not remove it. We tell you what we found, including what is marginal
