Corrugated / Arc Roof Sheet Roll Forming Line

1. Definition

A corrugated / arc sheet roll forming line produces corrugated roofing or cladding sheets in the corrugated-arc family documented under 01-ROOF-PANEL. It is distinct from Russian C-profile corrugated codes and from cross-direction arc presses that curve already-formed panels.

Public corrugated and arch-panel machines vary widely in station count and speed; commercial ratings still follow the named English quotation and proposal.

2. How it works

1. Load coil on the decoiler and feed into the mill
2. Guide strip to the selected feed-width path (1000 or 1350 mm class)
3. Progressive roll forming of the corrugated / arc wave profile
4. Hydraulic cut-to-length (about ±1 mm on the reference quote)
5. Exit / stack

3. Technical parameters

From the pack FAQ English quotation family:

Industry corrugated guides commonly cite about 0.3–0.8 mm light-gauge bands and 10–18 stations — market context only; do not overwrite the English quotation table above.

4. Thickness caution

The quotation thickness row is poorly formatted in source extraction. This encyclopedia page does not publish a single guessed thickness band. Open the original document row or confirm thickness in the contract.

Conflict note: Public market sheets for corrugated / arc lines often advertise about 0.3–0.8 mm or similar. Those are industry context only — not a substitute for the FAQ’s “do not invent thickness” rule.

5. Applications

• Corrugated roofing and cladding sheets for industrial and agricultural buildings
• Arc / wavy coverage where the finished drawing matches the corrugated-arc quotation family
• Not a substitute RFQ for trapezoid / IBR main panels or standing-seam lock panels

6. Related machines

• Cross-direction arc pressing — different configuration family with its own parameter source
• Russia C-series corrugated codes (C8, C20, C21…) — order by exact code; do not borrow wave height or speed from this arc quotation
• Post-form curving machines for already formed panels — auxiliary class, not this mill’s default scope
• Trapezoid / glazed-tile hosts — separate product leaves

7. Inquiry checklist

• Feed-width variant: 1000 mm or 1350 mm
• Finished drawing (wave height / pitch / cover width)
• Material grade and thickness (confirm from original quote row)
• Whether post-form curving is also required

8. Buyer FAQ

Is 1000 mm or 1350 mm enough to order?

State which feed-width variant you need, plus material and the finished drawing. Both widths appear on the same quote family as alternatives.

Can I use Russia C-profile speed here?

No. C-code lines are a separate quotation family with different wave geometry and drive packages.

What about thickness?

Confirm from the original quotation or contract. This page intentionally leaves thickness open.

Is an arch-curving press the same machine?

No. Cross-direction or post-form curving equipment is specified separately from this corrugated forming host.
