Floor Deck Roll Forming Machines: Open, Closed and Cover Widths

1. What a floor deck line actually makes

A floor deck (metal deck / composite deck) mill rolls a profiled sheet that becomes the permanent form and often the tensile reinforcement for a concrete floor slab. Cover width, rib depth and whether the ribs are open or closed decide the roll flower, stand count and coil feed width. Search traffic also lands “YX floor deck,” “composite deck machine” and “metal deck roll forming” on the same keyword — they are not one interchangeable host.

This page stays inside the single-sheet floor-deck host class documented below. Dual-layer deck and HS deck are different host classes and need their own quotations.

2. Open vs closed deck

3. Common single-sheet host class

Across the named cover-width builds that share this catalogue slot, the recurring single-sheet envelope is:

• Thickness class: 0.8–1.2 mm
• Host drive: 2 × 11 kW
• Hydraulic station: 5.5 kW
• Shaft: φ90
• Line speed: often 8–10 m/min; some EN quotations list 8–12 m/min

Stand count and coil feed width change with the named cover width — they follow the cover, not a guessed motor size.

4. Named cover widths

Cover width is the commercial name of the finished effective width. Coil feed is wider than cover. Stands are labeled per named build:

These rows sit on the same single-sheet host class in §3 unless a quotation explicitly says otherwise. A 36-stand 609 flower does not run on a 22-stand 688 shaft set by renaming a recipe.

5. Closed deck example: 600 class

Closed deck is documented as its own named row, not as “open deck with one more stand.”

6. What this page is not

• Roofing trapezoidal main lines — different flower, different duty, different encyclopedia.
• Glazed / step tile mills — roofing tile geometry, not floor composite deck.
• Dual-layer deck and HS deck — different host classes; quote separately; the 2 × 11 kW single-sheet numbers do not transfer.
• Open-profile sheets without a machine quote (e.g. YX51-305-915 knowledge only) — section data is not a stand-in for host kW.

7. Send the cover width, not “deck machine”

1. Open or closed; finished cover width and rib depth (drawing PDF)
2. Thickness and steel grade in the 0.8–1.2 mm class or outside it
3. Named cover (609 / 630 / 678 / 688 / 720 / 834 / 914 / 600 closed) if known
4. Coil width available at the plant vs required feed
5. Whether dual-layer or HS deck is also in the order (separate quotation)
6. Cut type and stacking preference

8. Buyer FAQ

Is a 914 cover the same mill as a 609 with different rolls?

No. The named builds list different stand counts and feeds (914: 28 stands / feed 1250; 609: 36 stands / feed 914). Treat them as labeled variants of the same single-sheet host class, not as a free roll swap.

Can I take host kW from an open YX51-305-915 sheet?

Not from profile knowledge alone. If the open sheet lacks a full machine quotation, host power stays blank until quoted.

Is closed 600 just open deck with closed ribs on the HMI?

No. The closed 600 example is 30 stands, feed 1250, FX114-200-600 / YX51-200-600 closed — its own named row.

Can dual-layer or HS deck use the 2 × 11 kW numbers?

No. Those are separate host classes and separate quotations.
