C47 furring machine · ceiling furring channel · C furs roll forming · omega light keelCeiling work uses light-gauge C furring, hat furr channel and omega (Ω) keels. They share a light-gauge ceiling family: φ40-style shafts on many rows, host power in a few kilowatts — not PEB purlin hosts.
“Hat purlin” and “omega purlin” searches often land on structural pages, but ceiling furring is a different family. This page covers the ceiling fork. Structural hat / sigma for PEB stays on the hat-purlin page, not here.
On the C47 recommend quotation:
| Item | On that C47 recommend quote |
|---|---|
| Speed | ~15–20 m/min |
| Host | ~4 kW |
| Stands / shaft | ~14 stands; φ40 |
| Thickness | ~0.4–0.6 mm |
C47 is the common ceiling furring channel inquiry. High-speed C-furs kW and PEB hat numbers stay on their own rows.
High-speed C furs is a separate speed tier in the same ceiling family:
| Item | On that high-speed C-furs quotation |
|---|---|
| Speed | ~0–35 m/min |
| Host / hyd / total | Host ~5.5 kW + hyd ~4 kW; total ~10 kW |
Use this row only when the offer is labeled high-speed C furs. It is not the default C47 recommend mill with a recipe change.
| Build | On that quotation | Notes |
|---|---|---|
| Hat furr channel | ~10 stands; φ40; envelope ~3800 × 800 × 1400 mm | Thickness often ~0.4–0.7 mm |
| Ω63 | ~10 stands / ~3 kW | Ceiling omega — separate row |
| Ω100 | ~12 stands | Ceiling omega — separate row from Ω63 |
Hat furr and omega sit in the same ceiling keel family as C47 / C furs. They are not the 22 kW solar strut or PEB structural hat lines on the hat-purlin encyclopedia.
If the drawing is a structural hat or sigma purlin for PEB roof or wall, you are on a different family. Thickness, stands and host leave the light-gauge ceiling band. Use the Hat Purlin Machines wiki — do not order a C47 ceiling mill for that duty.
65C wall stud is a different mill (~10 stands, ~3 kW, ~0.4–0.8 mm). Close in gauge to furring, different roll path — quote from the stud drawing, not from C47.
No. C47 recommend is ~15–20 m/min and ~4 kW host. High-speed C furs is ~0–35 m/min with host ~5.5 + hyd ~4 (total ~10 kW).
No. Ceiling hat/omega stay in the light-gauge ceiling family. Structural hat/sigma PEB belongs on the hat-purlin page.
No. Ω63 is ~10 stands / ~3 kW; Ω100 is ~12 stands. Separate rows.
Neighbor only: different mill (~10 stands, ~3 kW, ~0.4–0.8 mm). One stud path does not become C47 by renaming the HMI.
Speeds, kW, stands, shaft and thickness above come from the named C47, high-speed C-furs, hat furr or omega quotation.
