1. Why the confusion exists
A source file may sit in a standing-seam folder or carry “立缝 / standing seam” in the filename, while the document title reads KR 700 Wall Panel Machine. Catalog discipline follows the title and profile: KR700 is hung as a wall / cladding host. A separate standing seam making machine quotation supplies interlocking roof-panel parameters.
Industry buyer guides likewise warn that standing-seam formers and exposed-fastener / wall cladding formers are not interchangeable tooling sets — edge-in interlocking geometry is not a wall-rib clone.
2. Parameter comparison
| Item | KR700 wall panel (document title) | Standing seam roof (dedicated quote) |
|---|---|---|
| Thickness | ~0.4–0.8 mm | Supporting ~0.8–1.2 mm (Al-Mg-Mn style docs; also color / GI / Al listed) |
| Width | Feed ~914 mm; effective ~700 mm | Per standing-seam drawing (not KR700 700 mm cover) |
| Speed | ~15 m/min | ~25 m/min |
| Passes | ~28 | Confirm on standing-seam sheet (do not reuse 28) |
| Main / hyd | ~7.5 kW / ~4 kW | ~5.5 kW / ~3 kW |
| Structure | Shaft ~φ70; mid-plate ~20 mm; 1″ chain; stop hyd shear ±1 mm; length ~12 m class | Host ~7500×1650×1450 mm; mid-plate ~18 mm; shaft ~φ70; chain drive |
| Extras | — | Motor curving machine often offered in same project — curving is not the host rating |
Conflict call-out: never publish KR700’s 15 m/min / 7.5 kW / 28 passes as standing-seam roof specs, or the reverse. If the contract drawing is truly interlocking standing seam, reopen the standing-seam quotation.
3. How to classify the RFQ
- Wall KR700 path — effective ~700 mm wall panel from ~914 mm feed; exposed or wall-rib geometry per drawing
- Standing-seam roof path — interlocking seam height/clip rules; thickness often higher on Al-Mg-Mn docs
- Optional post-form curving belongs to an auxiliary — keep kW off the main former table
4. Boundaries
- Filename language does not override document title
- Not a trapezoid / IBR main line
- Not a mother-of-pearl 430 host (separate MOP quotes)
- Do not mix wall effective-width math into standing-seam pan width
5. Inquiry checklist
- Open the title block before trusting the filename
- Profile drawing: wall rib vs interlocking seam
- Thickness band and material family (color / GI / Al-Mg-Mn)
- Whether a curving accessory is also required
6. Buyer FAQ
The PDF is named “standing seam” — is it standing seam?
Open the title block. If it says Wall Panel Machine with ~700 mm effective width, treat it as KR700 wall unless the profile drawing shows interlocking seams.
Why can standing seam show lower main kW but higher speed?
Different thickness bands, pass designs, and shear packages. Compare full rows, not a single cell.
Where does the curving machine sit?
On standing-seam projects it is often an accessory. Its motor rating is not the ~5.5 kW host figure.
Can wall KR700 tooling make lock-seam roof panels?
Not as a casual changeover. Interlocking standing-seam geometry needs its own quotation and tooling path.
Ratings follow the confirmed technical proposal. Commercial quotes and lead time are out of scope.
