Closed Floor Deck Roll Forming Line (600 mm Effective Width)
Table of Contents
1. Definition
A closed floor deck roll forming line cold-forms steel strip into closed-type (narrow-mouth / dovetail-style) floor deck panels. A common reference coverage is about 600 mm effective width with about 1250 mm feed width. Alias names in source documents include FX114-200-600 and YX51-200-600 closed deck.
Not an open deck line, not a 609–914 mm effective-width open-family machine, and not a roof sheet line. Closed rib geometry is specified because it locks differently with concrete than open trapezoid decks — industry selection guides make the same open/closed split before discussing load or fire detailing.
2. Technical parameters (reference host)
| Item | Reference |
|---|---|
| Effective / feed width | ~600 mm coverage / ~1250 mm feed |
| Speed | ~8–10 m/min (Chinese quotation reference) |
| Main / hydraulic | ~2×11 kW forming / ~5.5 kW hydraulic |
| Stands / shaft | ~30 forming passes; shaft ~φ90 mm; rollers 45# / GCr15 |
| Drive / control | Chain drive; PLC/HMI/inverter (Panasonic, Delta, or Mitsubishi cited — do not lock one brand) |
| Thickness / material | ~0.8–1.2 mm; pre-painted, galvanized, or aluminum coil per quote language |
| Cut / auxiliaries | Hydraulic cut-to-length after forming; optional front shear in feed; ~5T manual decoiler common |
| Footprint / weight | Not listed in source evidence → confirm on the proposal (do not invent) |
3. Variants (do not merge)
| Sibling | Notes |
|---|---|
| Open deck profile (e.g. YX51-305-915) | Different rib family; may be profile-knowledge only without full machine ratings |
| Effective-width lines (609–914 mm) | Same “floor deck” market language, different tooling and pass/feed tables |
| Roof sheet / trapezoid roof line | Misfiled roof inquiries must not inherit closed-deck power or speed |
Market closed decks such as YXB51-200-600 illustrate the product geometry buyers mean by “600 closed”; machine ratings on this page stay on the documented forming-line reference, not on product-sheet marketing claims.
4. Process route
- Uncoiling (~5T manual decoiler in reference quotes)
- Feeding with optional front shear
- Chain-driven roll forming (~30 passes)
- Hydraulic cut-to-length
- Exit / support rack
5. Applications
- Closed-type floor deck / profiled steel production for steel-framed composite floors
- Projects that specify closed rib geometry rather than open trapezoid coverage
Fire rating, span capacity, and rebar reduction claims belong to the building design and contract test reports — not to the machine page alone.
6. Buyer FAQ
Is 8–12 m/min the closed-600 speed?
Not on this reference. The closed-600 quotation documents about 8–10 m/min. The 8–12 m/min band appears on some effective-width English quotes (for example 630 mm) — list both bands only when that width’s FAQ shows both.
Can I quote open-deck power here?
No. Keep closed-line and open-profile evidence separate.
Are overall dimensions published?
Not in the available evidence set. Ask for them on the confirmed proposal.
Final ratings follow the named technical proposal. Price and lead time are out of scope.
