Automatic C80-300 and C/Z Interchange Purlin Machines
C80-300 purlin machine · CZ interchange purlin · Cee Zed combined · automatic C purlin1. Two inquiries that get mixed
“Cee Zed combined,” “CZ interchange purlin,” and “automatic C purlin” searches land on one inquiry, but they are different quotation tiers:
- Automatic C80-300 — C single, size change inside a C envelope.
- C/Z interchange — packages that change web/flange and, on some schemes, flip C to Z.
Host kW, speed and thickness come from the named table. Automatic C numbers stay on the Automatic table; each CZ scheme keeps its own row.
2. Automatic C80-300 (C single)
On the Automatic C80-300 FAQ table:
| Item | On that Automatic table |
|---|---|
| Forming speed | ~0–18 m/min |
| With punch / cut | ~0–12 m/min |
| Host | ~15 kW |
| Stands / shaft | ~14 stands; φ80 |
| Thickness (recommend) | ~1.0–3.0 mm (G345 class) |
| Section envelope | On the Automatic table: “Height 40–80 mm, Width 80–300 mm, Lip 10–20 mm” — exact wording from that quotation |
In market speech, C80-300 usually means a C purlin whose web height adjusts roughly 80–300 mm. The Automatic table above swaps the usual height/width labels (height 40–80, width 80–300). Treat the table as what that quotation says, not as industry naming. Send the dimensioned drawing before locking rolls or quoting changeover range.
3. Other C configurations (not the Automatic table)
Other C builds exist in the catalogue. Label them as OTHER configs, not as the Automatic C80-300 standard:
- Gearbox flying-saw class — ~30 m/min
- Heavy C host class — ~55 kW host
- KR high-speed class — ~50 m/min (speed class on that config)
These are OTHER C configs — name the config on the RFQ; they are not interchangeable with the Automatic C80-300 table.
4. C/Z interchange quotation tiers
C/Z (Cee Zed combined / CZ interchange) schemes in the FAQ are multi-tier. Each row keeps its own label:
| Scheme (label) | Speed | Power on that quotation |
|---|---|---|
| Chinese 2.0–3.0 scheme | ~20 m/min | Host ~15 kW |
| EN Standard / New | Form ~0–15 m/min; prod ~0–12 m/min | Host ~18.5 kW; hyd ~7.5 kW |
| Quickly | Form ~0–25 m/min; prod ~0–18 m/min | Host ~22 kW |
| Heavy Chinese | (scheme-specific) | Host ~37 kW |
| Servo strengthen | High speed ~30 m/min with punch | ~22 kW servo + hyd ~7.5 kW |
Changeover hardware (manual / hydraulic / servo size change, C↔Z flip) is package-specific. Ask which scheme name is on the offer before comparing speed or kW.
Heavier servo-changeover tiers (42 kW class with punch-cut) are quoted on the Hydraulic Purlin Machines page — name the quotation before comparing servo kW across pages.
5. Thickness bands by CZ scheme
| CZ scheme | Thickness on that quotation |
|---|---|
| Chinese | ~1.6–3 mm |
| EN Standard | ~1.5–3.2 mm |
| Quickly | ~1.5–3.5 mm |
Automatic C80-300 recommend thickness (~1.0–3.0 mm, G345 class) stays on the C-single table above. CZ thickness bands stay on the CZ table; Automatic C keeps its own recommend range.
6. What these mills are not
- Hat / omega / structural hat — brim flower, not C/Z lips. See the hat-purlin encyclopedia.
- Sigma purlin — different section and mill family.
- I purlin — compared on the I-vs-C/Z wiki; not a CZ interchange recipe.
- Light-gauge CU stud — drywall / light steel framing duty, not PEB purlin thickness or punch patterns.
7. Send the section and the scheme name
- C-only (Automatic C80-300 class) vs C/Z interchange — say which
- For CZ: scheme name (Chinese / EN Standard-New / Quickly / heavy Chinese / servo strengthen)
- Finished C or Z section with web, flange, lip; PDF preferred
- Thickness and grade (match the band for that table)
- Punch pattern and whether punch runs with production speed
- Cut: stop vs flying / tracking
- Whether C↔Z flip is required on the same mill
8. Buyer FAQ
Is Automatic C80-300 the same as CZ interchange?
No. Automatic C80-300 is C single on its FAQ table (~15 kW host, ~14 stands, φ80). CZ interchange has its own scheme tiers and thickness bands.
Can I use the ~55 kW heavy C host numbers on an Automatic RFQ?
No. Heavy ~55 kW, gearbox flying saw ~30 m/min, and KR high-speed ~50 m/min are OTHER C configs — label them separately.
Why does the Automatic table say height 40–80 and width 80–300?
That is the literal wording on the Automatic C80-300 quotation (Height 40–80 mm, Width 80–300 mm). Buyers usually call C80-300 a web-height range of ~80–300 mm. The table may use different labels — confirm web, flange and lip on the PDF.
Which CZ scheme is “standard”?
There is no single public standard on this page. Compare Chinese, EN Standard/New, Quickly, heavy Chinese, and servo strengthen as labeled rows.
Speeds, kW, stands and thickness above come from the Automatic C80-300 FAQ table or the named CZ scheme quotation. Other C configs are called out separately.
