We check the wire before it is formed, the drawing before it is built, the trial before bulk production and every belt before it is packed. You see the measurements at each step.
A belt is only as consistent as its wire. We buy wire rod and round bar from established steel mills, draw them to size on our own lines and check every batch before forming.
| Material | When | Checks |
|---|---|---|
| 5.0 mm wire rod | On arrival | Composition by spectral analysis against the grade · diameter · heat number recorded |
| 12 mm round bar | On arrival | Composition by spectral analysis against the grade · diameter · heat number recorded |
| Drawn wire | Every drawn batch | Diameter to your drawing · tensile test · hardness · sample kept |
| Drawn rod | Every drawn batch | Diameter to your drawing · hardness · sample kept |
For your order: the material used is recorded for every belt, wire samples are kept, and material documentation is available for your order. Third-party laboratory re-testing can be arranged on request. Final dimensions and tolerances follow the drawing you sign.
Nothing is built in volume until you have approved it.
Defined checkpoints at forming, welding and assembly, so a deviation is caught on the first metres.
Examples from our defect photo library, used to train inspection. A belt that does not meet the approved drawing does not go to packing: it is recorded, reworked or remade, and inspected again.
Every finished belt is checked against the approved drawing, and you receive the numbers.
Each order is linked to its material, production, inspection and approval records.

Inspection is only useful if it is allowed to reject.
On a 2,550 mm SUS304 balanced weave belt for a European distributor, our first trial section did not hold its width. We rejected it in our own workshop and built a new one. The new trial was measured over ten spiral and rod pitches and photographed next to the original sample before the distributor approved mass production.
That is the standard for every order: the belt you receive is the one that passed, not the first one we made.
No. It starts with spectral checks on incoming rod and bar, continues with the drawing, the trial section and in-process checks, and ends with 100% final inspection before packing.
Yes. Material documentation is available for your order, and the material used is recorded for every belt.
Yes, where the project requires it, especially for new designs and replacements from a sample. Bulk production starts after you approve.
Yes. Every finished belt is checked against the approved drawing before packing. This is a check of every belt, not a zero-defect or lifetime promise.
Spiral freezer and side driven belts are turned or drum-tested to the approved drawing where the project requires it. Every self-stacking belt order is hand-stacked and checked at the turning diameter before shipment.
Yes. Buyer audits and third-party inspection can be coordinated, and third-party laboratory re-testing can be arranged on request.
