    Hat Purlin Forming Line

    A hat is web + two sides + two brims. Ceiling furring, solar strut and a compact shop hat+U share the silhouette. They do not share the station list.

    Operation steps

    Board the hat drawing

    Board the hat drawing

    If cooling is on all 24 passes, a dry bank is incomplete. Compact twin uses stop-cut, not tracking.

    Confirm hall voltage

    Confirm hall voltage

    The compact twin is 220 V / 1φ. The strut mill uses the voltage on its own quotation.

    Form the brims

    Form the brims

    Watch brim flare. A C mill will not grow those returns.

    Cut as specified

    Cut as specified

    Strut: first-off at tracking speed. Compact: stop-cut on 3 m tables. Run one compact host at a time unless the proposal says both live.

    What's included

    This line

    This page: How to pick and run a hat host: 24-pass strut or compact twin hat+U.

    Standard build

    Sister lines: C/Z changeover, CUZ size-change, and ceiling furring each have their own quotation.

    Key details

    Which mill is live

    24-pass tracking versus 12-stand stop-cut. Name it on the first-off tag.

    Power & voltage

    380 V 3φ vs 220 V 1φ — Wrong hall voltage is a fail before the first coil.

    Brim widths vs CAD

    Web, twist and brim. A Cee sample is not a hat first-off.

    FAQ

    Is a solar strut mill the same as a compact hat+U twin?
    The strut host is 24 passes, 22+5.5 kW, 380 V / 60 Hz, tracking cut. The compact twin is 12 and 10 stands, 5.5+5.5 kW each, 220 V / 60 Hz / 1φ, stop-cut.
    Can ceiling furring numbers sit on the strut mill?
    C47 furring (~14 stands, ~4 kW) is a ceiling mill. The 24-pass strut keeps its own kilowatts.
    How are price and lead time quoted?
    Send the hat drawing, thickness and site voltage. Commercial terms come back on the offer.
