Roller Shutter Door Slat Roll Forming Line

1. Definition

A roller shutter door slat line forms interlocking curtain slats (Chinese 卷帘门帘片). English names include roller shutter door / shutter door roll forming machine. Recommended baseline is the 2019 English shutter-door quotation (about 0–20 m/min, main about 11 kW, hydraulic about 3 kW, about 16 rolls on φ70).

Single-layer Chinese, European thin (e.g. 55 class), and PU double-layer are same-family variants with different speed and thickness wording — publish side by side, never as one forced band.

2. Process and applications

Recommended single-layer wording:

1. Decoiling / pay-off
2. Feeding and leveling (may be integral)
3. Roll forming
4. Hydraulic cut-to-length (optional synchronized punching)
5. Exit / stacking

PU double-layer setups add foaming, heating, reshaping, and tracking cut-off — do not describe every slat line as if those stages were included by default.

Applications. Batch production of shutter slats for shops, warehouses, and similar buildings. Materials are often galvanized steel or stainless (e.g. 304 on the recommended wording). Not a door-frame machine; not a garage continuous foaming panel line; not a guide / slide / box line.

4. Conflicts and open items

• Speed tiers — 0–20 vs ~10 vs ~8–10 vs ~25. Name the variant.
• Power tiers — 11/3 vs 5.5 vs PU combo vs 3 kW accessory. Never paste accessory power onto the slat host.
• Thickness tiers — CS 1.5/1.6 vs single 0.8–1.2 vs European 0.25–0.35 vs PU 0.4–0.9 (max-0.6 conflict on some PU sheets).

5. Boundaries (related machines)

• Guide / slide / shutter-box line — Side rails and hoods; section-tiered power (~7.5 to ~75 kW).
• Door frame / leaf line — Hinge/lock punching before form; different section.
• Garage continuous foaming panel — Wide insulated garage panels; not PU slat.
• Octagon tube — Winding shaft; often bought with a full shutter project but separate ratings.

6. Buyer FAQ

Same as a guide rail or shutter-box machine?

No. Guides, slides, boxes, and rails are a separate section family with their own power tiers.

Can one host run two slat profiles?

Yes when the proposal includes full roll-set change (or cassette tooling). It is not a free default on every single-profile machine.

Is the English 11 kW the same as Chinese single-layer 5.5 kW?

No. They are different configuration tiers. Label which package the quote follows.

Do I need guides and octagon tubes on the same RFQ?

A complete shutter project often needs them, but they are separate machines/parameters — do not paste their kW onto the slat host.
