    1. Definition

    This page answers a recurring sales failure mode: treating a box / square gutter inquiry as if the rain-gutter or half-round datasheet already covers it. In the documented pack, box gutter is a real product category (profile drawing + forming video), yet complete machine ratings are missing. Therefore public encyclopedia and CMS answers must demand a separate technical proposal instead of inventing numbers.

    Industry box-gutter builders likewise start from customer drawings (width, leg height, material, gauge) before locking stations, kW, and speed. That commercial practice matches the blocked status here.

    2. When this question appears

    • Buyer sends only a square-gutter photo or DWG and asks for “standard speed and power”
    • Sales drafts a quote by copying rain-gutter 10–12 m/min / 4.0 + 3.0 kW
    • Marketing wants a numeric table on the box-gutter product card before engineering signs off
    • A portal auto-answer tries to fill empty cells from sibling gutter FAQs

    Correct handling: keep the category page visible as a category page, keep this page as the policy page, and only unlock numeric bands after a named proposal is filed against the customer drawing.

    3. What is blocked vs confirmed

    TopicStatus
    Product category (box / square eaves trough)Confirmed — drawing + video
    Forming speedBlocked — do not invent
    Main / hydraulic kWBlocked
    Pass count / shaft / envelope / massBlocked — drawing ≠ host spec sheet
    Thickness bandBlocked
    Line BOMBlocked
    Minimum inputs for a proposalFinished profile drawing, material & gauge target, required length accuracy, voltage, whether plant or portable duty is expected

    Market pages may show portable 7-inch box machines or plant lines with their own bands. Cite them only as industry context — never as ZTRFM box ratings on this entry.

    Forbidden fill sources (explicit): rain-gutter FAQ, half-round FAQ, downpipe YX/English FAQs, and unlabeled competitor datasheets. Allowed fill source: a ZTRFM technical proposal that names the box profile drawing.

    4. Boundaries

    • Rain-gutter baseline (about 10–12 m/min, 4.0 + 3.0 kW) is not a box placeholder.
    • Half-round baseline (about 3–8 m/min, 5.5 + 3 kW, φ50) is not a box placeholder.
    • Downpipe YX sheets never answer box-gutter host questions.
    • Price and lead time stay out of encyclopedia scope even after the proposal exists.
    • Do not treat the square-gutter DWG dimensions as shaft diameter, pass count, or motor kW.

    5. Buyer FAQ

    Why can’t we publish “typical” box numbers from the market?

    Because this encyclopedia only publishes documented FAQ ratings. Market figures are unlabeled third-party proposals.

    Is the square-gutter video enough evidence for a speed claim?

    No. Video proves the category exists; it does not quantify m/min or kW.

    What should the sales reply be today?

    Confirm box profile from the drawing, state that host ratings need a named technical proposal, and refuse rain/half-round substitution.

    After the proposal is signed, where do numbers go?

    Into the contract and a revised encyclopedia revision — not into silent edits of the rain-gutter page.

    Final ratings follow the confirmed technical proposal. Price and lead time are out of scope.
