Two 3D fence quotations can both say “4.0 mm”—but the numbers may not be based on the same measurement stage.
If one quotation refers to the wire diameter before powder coating and another refers to the finished diameter after coating, the two figures cannot be compared directly.
Why does this matter to the buyer?
– It helps compare quotations on the same basis.
– It clarifies the wire specification behind the finished panel.
– It gives the purchase order a clearer acceptance requirement.
– It can reduce specification disputes during pre-shipment inspection or after delivery.
For this production sample:
– Before powder coating: 4.93mm
– Finished diameter after coating: 6.21mm
– Mesh opening: 60×200mm
Before comparing prices, ask the supplier to confirm:
1. Wire diameter before powder coating
2. Finished diameter after coating
3. Mesh opening
4. Coating system
5. Measurement method and permitted tolerance
Important: A larger finished diameter does not automatically mean better coating quality. The change in outside diameter is not a certified coating-thickness result. Coating thickness should be verified using the specified instrument and test method.
Clear specifications make quotations easier to compare and delivered products easier to inspect.
