How Should a Metal Conveyor Belt Be Inspected Before Shipment?
A belt that leaves the factory unchecked becomes your problem at installation. The inspection is your last chance to see it.
Short answer
A metal conveyor belt should be inspected against the approved drawing before packing: width, length, pitch, wire and rod, edges and welds, flatness and squareness, a turning or drum check where the design needs it, and cleanliness. You should receive measured photos and an inspection report before the belt ships.
I am Sunny Ye, Global Sales Director at YIYI MESH BELT in Ningjin, Shandong, China. Our manufacturing experience dates back to 1998. Every finished belt is inspected before packing in our workshop, and buyers receive the numbers.

Which dimensions should be checked?
Check what the drawing says, with the tool in the photo.
Check the dimensions on the approved drawing: overall width at several points, length, pitch over ten pitches in each direction, wire and rod diameters, and edge or chain dimensions. Each reading should be photographed with the caliper or tape visible, so you can check it yourself.
| Check | How |
|---|---|
| Width | Tape, several points |
| Pitch | Over ten pitches, both directions |
| Wire and rod | Caliper |
| Edge or chain | Caliper, against the drawing |
| Length | Measured and recorded |
What about welds, edges and flatness?
Dimensions can be right while the belt is still wrong.
Check that welds are even and do not stand proud of the links, edges are smooth and free of burrs, the mesh lies flat, and the belt is square with equal diagonals. Defects such as a cracked link or uneven welds are rejected, reworked or remade before packing.
Our inspectors work from a defect photo library: mesh not flat, uneven edge welds, welds proud of the link, cracked links. Each one has a defined action.
Which functional checks are needed?
Some belts must be seen working before they ship.
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, and sprockets supplied with a belt are checked against it. A white-glove wipe shows the surface is clean and oil-free before packing.
For a frying-equipment maker, the finished chain driven belts were wiped with white gloves and filmed before packing.
What should you receive?
The inspection is useful when you can see it.
You should receive measured photos, the inspection report of your own belt, packing photos and, where agreed, a video. Ask for them before the shipment leaves. Third-party inspection can also be arranged on request, and the records are kept with the order for repeat orders.
Final inspection checks every belt against the approved drawing. It is a check of every belt, not a zero-defect or lifetime promise.
When this is not the right choice
A general factory certificate is not a substitute for the inspection of your own belt.
Inspecting against the old belt instead of the approved drawing is not right; the drawing is the reference.
From our engineering experience
For a frying-equipment maker in East Asia, three chain driven belts were measured on a trial section, then checked again before shipment with a white-glove cleanliness check, measured photos and a video.
My advice: write your inspection requirements into the order. We plan them with production instead of adding them at the end.
Evidence from our work
- Situation
- Three SUS304 chain driven belts, 145 m each.
- What we checked
- Chain pitch, roller, inner width and rod spacing measured; white-glove cleanliness check; measured photos and video before shipment.
- Why it matters
- The customer saw the numbers and the cleanliness of their own belts before they left.
- Result
- About 436 m shipped with spares and material documentation.
- Buyer lesson
- Ask for measured photos and the report of your belt before shipment.
FAQ
Is every belt inspected?
Yes. Every finished belt is checked against the approved drawing before packing.
Can I see the inspection?
Yes. Measured photos, the inspection report and packing photos are sent before shipment; a video call can be arranged.
Can a third party inspect?
Yes, on request.
What happens if a belt fails?
It is recorded, reworked or remade, and inspected again before packing.
Conclusion
Check dimensions, welds, flatness, function and cleanliness against the drawing, and receive the photos and report before the belt ships.
