Open Floor Deck Profile YX51-305-915 (Profile Reference)

1. Definition

YX51-305-915 is an open-type floor deck profile reference — geometry and application knowledge, not a complete machine quotation pack. Trade aliases for this 51 mm open profile include 2W-305 (2-inch rib height, not a two-wave shape) and YL51-915. Do not treat YX76-305-915 / YXB76-305-915 (about 76 mm rib / 3W) as the same model — they share 305 mm pitch and 915 mm cover but not wave height. Public product pages describe the same naming logic: wave height ~51 mm, pitch ~305 mm, effective cover ~915 mm.

Use this page to confirm the deck shape. Do not treat it as a substitute for a 914 mm effective-width forming-line datasheet or a closed-600 machine proposal.

2. Profile geometry (documented)

Neighboring 76 mm / 3W decks are often quoted on ~1220–1250 mm coil; lock the actual feed width on the machine proposal rather than assuming 1200 mm for this 51 mm profile.

3. What this is not

• Not a closed deck machine profile (for example YX51-200-600 closed)
• Not YX76-305-915 / 3W (76 mm open deck with the same 305 mm pitch and 915 mm cover)
• Not automatically interchangeable with a 914 mm effective-width forming line without engineering review
• Not roof sheet / roofing panel equipment

4. Machine-side status

Available evidence covers profile geometry and composite-floor application notes. The following are not established in current source documents and must not be invented:

• Forming speed
• Main motor / hydraulic power
• Pass count, shaft diameter, overall footprint
• Full line auxiliaries BOM
• Machine-side thickness band (do not copy ~0.8–1.2 mm from other deck machine quotes onto this profile-only entry)

When a buyer needs production equipment for this profile, request a dedicated technical proposal built from the drawing.

5. Applications

• Multi-story steel building composite floor systems where open deck profiles are specified
• Permanent formwork contexts that accept open rib geometry

Fire-performance or marketing advantages mentioned in profile literature remain subject to project codes and contract tests.

6. Buyer FAQ

Why is there no speed on this page?

Because machine-side speed evidence is blocked in the source FAQ. Publishing a neighboring width’s 8–10 or 8–12 m/min here would invent a rating.

Is 915 the same as 914?

No. Similar coverage numbers belong to different evidence packs — one is open profile knowledge; the other is an effective-width machine reference.

Can I order rolls from this page alone?

You can start from the drawing, but station count, power, and shear package still need a forming-line proposal.
