Trapezoidal / IBR Roofing Sheet Roll Forming Lines

1. Definition

A trapezoidal / IBR roofing sheet roll forming line cold-forms trapezoid or IBR (inverted box rib) style roof and wall sheets from coil. English product language includes trapezoidal roofing sheet roll forming machine and IBR metal roofing panel making machine. Mid-plate frame directories and guide-post structure directories both exist — parameters must be tied to the named quotation file.

This encyclopedia title covers the trapezoid / IBR product family for buyer navigation. It does not authorize merging every mid-plate and guide-post quote into one thickness / speed / kW band.

Industry IBR / trapezoid machines are the workhorses of warehouse and industrial metal roofs: progressive roller stations create structural ribs, then hydraulic cut produces fixed lengths. That market role is shared; numeric answers on this page stay in the separate tiers below.

2. Process and applications

Common process for this family:

1. Uncoiling
2. Feeding / guiding (leveling when the proposal includes it)
3. Multi-pass roll forming of trapezoid / IBR ribs
4. Hydraulic or configured shear
5. Exit / stacking

Applications. Industrial warehouses, commercial roofs, agricultural buildings, and utility covers where exposed-fastener trapezoid / IBR sheets are specified. Not standing-seam lock panels, not glazed step tiles, and not double-layer dual-profile hosts unless the inquiry explicitly names a double-layer quotation.

3. Reference parameters (named tiers — do not merge)

Another guide-post folder trapezoid roofing quote may list shaft about φ80 and hydraulic about 3 kW with other differences — answer by naming that file; do not merge it into the 20170109 row.

4. Conflicts and open items

• Three mid-plate power / speed stories — 12 m/min, 18–20 m/min, and 20–25 m/min are different documents. Publishing “about 12–25 m/min” as one truth is forbidden.
• Guide-post vs mid-plate — Different frame families and shaft sizes (φ85 / 90 vs φ95). Structure choice is part of the inquiry, not a footnote.
• Double-layer quotes in guide-post folders — Belong to double-layer encyclopedia titles (standard / high-speed classes). Do not answer single-layer trapezoid with double-layer numbers.
• Gantry trapezoid directory — Separate majestic-profile evidence path; not a generic mid-plate parameter dump.

5. Boundaries (related machines)

• Guide-post trapezoid (named quote) — Same product family, different structural folder; cite 20170109 or the other named file.
• Double-layer roof lines — Two roll stacks; space-saving dual-profile hosts.
• Standing-seam / YX65-430 lines — Concealed-fastener lock panels.
• Glazed tile / step-tile lines — Decorative pitched tile look with step press.
• Ridge-cap lines — Peak accessories, not full-width IBR sheets.

6. Buyer FAQ

Which speed should we publish on the website?

None as a single merged band. Name the quotation tier (low-config, 7.5 kW doc, 11 kW doc, or guide-post 20170109) that matches the offered machine.

Is IBR the same as every trapezoid?

IBR is a widely marketed trapezoid / inverted-box-rib style. Exact rib geometry still needs the drawing — “IBR” alone is not a substitute for the profile print.

Can guide-post φ95 numbers answer a mid-plate 7.5 kW inquiry?

No. Keep shaft, host length, hydraulic kW, and speed with the named file.

Where do double-layer trapezoid quotes go?

To the double-layer encyclopedia entries. Do not fold them into this single-layer trapezoid / IBR page.
