A 6-inch half-round gutter machine forms a semicircular trough. A general rain-gutter line forms the broader eaves-trough family documented on the rain-gutter quotation (commonly aligned with K-style / multi-arc commercial profiles in the market). They are sibling gutter hosts, not interchangeable datasheets.
Industry comparisons note that K-style / ogee profiles usually need more complex contour control, while half-round tooling prioritizes concentric arcs. Use that only to explain why speeds and shafts differ — keep numeric answers on the FAQ baselines.
Selection cue: if the drawing is a smooth semicircle at 6-inch class, open the half-round host. If the drawing is a multi-arc / ogee-style or general rain trough on the rain-gutter quotation family, open the rain-gutter host. If angular box geometry appears, leave this comparison and open the box proposal policy.
| Item | 6-inch half-round | Rain gutter baseline |
|---|---|---|
| Speed | About 3–8 m/min | About 10–12 m/min |
| Forming / drive power | About 5.5 kW | About 4.0 kW |
| Hydraulic | Cut motor about 3 kW | Station about 3.0 kW |
| Passes | About 18 | About 18 |
| Shaft | About φ50 mm | About φ70 mm |
| Drive note | Bidirectional chain P=25.4 | About 0.6 inch chain; Delta PLC class |
| Thickness | About 0.4–0.8 mm | About 0.3–0.7 mm |
| Envelope | About 8.8×0.7×1.0 m | Whole-line envelope blocked |
| Decoiler note | Cantilever about 1–2 T; coil width about 300 mm | 3T manual decoiler cited |
| PLC brand lock | Not locked — do not invent | Delta PLC / HMI / inverter class |
No. Both cite about 18 passes, but shaft, speed, power, and profile geometry differ.
The rain-gutter baseline documents a higher band (about 10–12 m/min). That does not make it the correct host for a half-round drawing.
Only if a multi-profile proposal is written that way. Default encyclopedia answer: separate hosts.
Neither — ask for the profile. Half-round uses about 0.4–0.8 mm; rain gutter uses about 0.3–0.7 mm; they are not a single published band.
Final ratings follow the confirmed technical proposal. Price and lead time are out of scope.
