Standing Seam Lock Roof Machines
1. Lock is a system, not one motor
Searchers write lock roof machine for the mill that rolls standing-seam legs. On a mechanical-seam roof the mill is only the first crate. Clips fasten to the deck; a seamer (electric or tongs) folds the legs together. Snap-lock / clip-lock panels that click without a seamer are a different roll path.
The standing-seam encyclopedia already publishes one quotation baseline (0.8–1.2 mm, ~25 m/min class). This page is the lock-system landing: mill, seamer, clips, and the wall-panel mill that must not be merged.
2. Snap-lock vs mechanical seam
| Mechanical / seamed | Snap / clip-lock | |
|---|---|---|
| On the roof | Electric closer walks the rib; single lock (90°) and double lock (180°) are different jobs | Legs snap over a clip; no seamer pass if the profile is truly snap-lock |
| On the mill | Lock-leg geometry + often a site seamer in the same order | Different flower; portable snap-lock family exists as a labeled brochure class |
Ask which lock the drawing shows. A wall-panel mill can still be sold under a standing-seam name — KR700-class in that family is a wall panel.
3. Named panel hosts
| Build | Strip / speed / power on that quotation | Notes that stay on that quotation |
|---|---|---|
| Wiki standing-seam host | ~0.8–1.2 mm; ~25 m/min; main ~5.5 kW; hyd ~3 kW; φ70; chain; host ~7500×1650×1450 mm | Al-Mg-Mn hardness follows that quotation; motor curving is a separate auxiliary |
| KR18 floor-type (process library) | 0.4–0.8 mm; infeed 600 mm stated; 11 passes; 10–13 m/min; main 5.5 kW; hyd shear 3 kW CR12MoV; 3 t manual decoiler | Package includes 1× electric seamer + 3× manual tongs; factory test 0.6 mm, 380 V/50 Hz |
| Guide-pillar auto-slide standing seam | 0.5 mm PPGI/PPGL; infeed 460 & 625 mm stated (if CAD lists 416 mm, the pattern board wins); 20 passes Ø70; ~8 m/min; main 7.5 kW | Decoiler is listed as an accessory, not a major unit; hyd notch then hyd cut+bend; width motors 2×0.75 + 1×1.5 kW; 380 V/50 Hz |
| Portable standing-seam former | Coverage 245–625 mm adjustable; seam heights ~24 / 25 mm on that board | Related snap-lock brochure (~0.4–0.6 mm, ~12 stations, ~3+3 kW) — confirm on the portable former you buy |
YX65-430 / mother-of-pearl is another standing-seam family with its own two ratings. Those speeds stay off the 25 m/min host and off the 8 m/min slide mill.
4. What closes the seam on the roof
An electric seam closer in this catalogue is specified for already-formed legs: seam height 50.8 mm (2″), must sew single lock and double lock (board: 90° single, 180° double). Coverage on that board about 12″–24″. Related packages often list ~2.4 kW / 220 V / ≤0.8 mm — confirm on the seamer you buy.
KR18 ships an electric seamer plus three manual tongs as accessories of that host. Tongs are not a mill.
Fixed clips on one order are parts, not a forming machine: Aluzinc 1 mm, height ~38 mm, 76.2 mm (3″) mark, qty 10,000, with tongs in the kit. Clip roll forming would be a different process.
5. What is not a lock-roof mill
- KR700-class wall panel — a wall mill. Open the wall quotation; lock-leg ratings on this page do not apply.
- Trapezoid / IBR — exposed fasteners, no lock legs.
- K-span arch + sew — beamless shell, different machine (next encyclopedia).
- Floor-type vs slide vs portable — three packaging classes, not one speed.
6. RFQ that names lock height and coverage
- Finished panel drawing: coverage, rib height, snap vs mechanical
- Thickness and alloy (PPGI vs Al-Mg-Mn vs aluminium)
- Shop mill vs portable / jobsite
- Seamer: electric single/double lock, seam height, voltage
- Clips: buy parts or form them
- Curving yes/no as a separate machine
7. Buyer FAQ
Is the seamer included in a lock roof machine?
Only if the quotation lists it. KR18 in this catalogue includes one electric seamer and three tongs. The 2″ closer quotation is a finish tool, not a roll former.
Can I run KR18 numbers on the 0.8–1.2 mm wiki host?
No. KR18 is 0.4–0.8 mm and 10–13 m/min. The wiki standing-seam host is 0.8–1.2 mm and ~25 m/min.
Does 7.5 kW on the slide mill match a wall-panel mill?
Same integer, different machines. Slide is 20-pass 0.5 mm at ~8 m/min. A wall-panel mill is a different quotation.
Family-typical seamer kW is labeled as family. Commercial terms come back on the offer.
