Short answer: you cannot compare screen mesh quotations by reading the unit price line. A quote is only comparable when every quote is normalized to the same fields — mesh count, material, roll width and length, unit basis, packing and commercial terms. “18×16 at $X per roll” from two suppliers is usually two different products at two different price bases.
Why raw price comparison fails
Screen mesh is quoted in several unit bases and several product constructions. Common reasons two quotes look different without being different — and vice versa:
- Different roll formats — one quote in 36-inch × 100-foot rolls, another in a different width or length.
- Different unit bases — per roll, per square meter, per square foot, per container.
- Different material families — fiberglass vs polyester vs PP/PE quoted under a similar product name.
- Unstated construction fields — yarn, unit weight and coating left out of the quote line.
- Packing and commercial differences — carton vs pallet, label requirements, MOQ and lead time sitting outside the quoted price.
None of these makes a quote wrong. All of them make it non-comparable until normalized.
The six-step comparison
1. Write every quote into the same field list
For each quote, record at least:
Mesh count
Material and coating
Roll width × length
Color
Unit weight (if stated)
Unit basis (per roll / per m² / per ft² / per container)
Packing and labeling
MOQ and lead time
Included items (sample, documents) and exclusionsIf a field is missing, the quote has not defined it yet — ask, rather than assuming it matches the other quote.
2. Normalize to one unit basis
Convert every quote to the same unit before comparing. The conversion depends on the roll format:
- per roll → divide by roll area (width × length) to get a per-area basis;
- per area → multiply by your roll format to compare on your purchase basis;
- state the basis on the comparison sheet so it does not get lost.
The point is not precision theater — it is making the two numbers actually comparable.
3. Separate product fields from commercial fields
Product fields (mesh, material, roll format, unit weight, color) determine whether the quote describes what you need. Commercial fields (price, MOQ, lead time, packing quantity, tooling or surcharges) determine the conditions. Compare them as two layers, not one lump:
- first: do both quotes describe an acceptable product construction?
- second: given acceptable constructions, which commercial package fits?
Private label and custom packaging are available capabilities; their exact structure, artwork and surcharge are part of the commercial layer and are confirmed per order.
4. Check against your reference, not against competitor claims
The quote should be compared against the reference you already trust — the current roll label, a written specification, or an approved sample. Reference values from other public catalogs describe those products, not the quoted one.
5. Price the differences, don’t ignore them
If one quote is cheaper “for the same 18×16,” the difference usually lives in yarn, unit weight, coating or packing. Decide which fields matter for your application and ask for those values — a small difference in weight can be a real difference in product.
6. Keep the comparison as your order record
The normalized comparison sheet becomes the basis for the purchase order. Carrying the same fields into the container order control — sample, specification, PO, packing and shipment documents — prevents the comparison from evaporating once the order starts.
A simple comparison sheet
| Field | Supplier A | Supplier B | Notes |
|---|---|---|---|
| Mesh count | 18×16 | 18×16 | same nominal count |
| Material | fiberglass, PVC coated | polyester | different family — compare carefully |
| Roll format | 36″ × 100′ | 40″ × 100′ | normalize to area basis |
| Unit basis | per roll | per m² | converted before comparing |
| Unit weight | not stated | not stated | ask both |
| Packing | carton of 10 | pallet, shrink-wrapped | check damage risk and handling |
| MOQ / lead time | per quote | per quote | commercial layer |
When to stop comparing and ask
- when a quote omits material or mesh count — “insect screen” is not a specification;
- when two quotes use different roll formats and the conversion changes the ranking;
- when the price difference is large and no construction field explains it;
- when the current reference (label, sample) has not been confirmed against either quote.
These are normal questions, not supplier resistance. A good supplier answers them in writing.
