    Arch Roof Forming Line

    A jobsite K-span forms flat, then curves, then sews. A shop arch-beam rolls the radius in the last stand. They are two first-offs.

    Operation steps

    Form flat to developed length

    Form flat to developed length

    Footer-to-footer. Arch speed is the next mode, not this step.

    Curve to the engineering radius

    Curve to the engineering radius

    Not the shop Ø110 last-stand template. Then seam the shell.

    If the order is shop arch-beam

    If the order is shop arch-beam

    Form nine stands as a beam. Last stand sets the arch. First-off: PLC angle vs template, both-end 1 cm bend, 30 m span only as that sheet’s max.

    Corrugated shear-bend is another mill

    Corrugated shear-bend is another mill

    18 stands, 7.5 kW forming main, hyd bend 5.5 kW after form. Standing-seam motor curver is auxiliary to a seam mill.

    This page: How to run MIC240 three-speed on site, and how the shop Ø110 beam first-off differs.

    Standard build

    Sister lines: Large-span arch beam, corrugated sheet, and standing-seam mill each have their own quotation.

    Key details

    Three MIC240 speeds stay three

    One blended “line speed” fails this specification.

    Jobsite vs shop beam

    914→610 is not 1200 mm feed Ø110.

    K-span sew vs 2″ seamer

    Lock-panel closer is a different tool.

    FAQ

    Why are there three speeds on MIC240?
    Flat form ~15 m/min, arch ~13 m/min, seam ~16 m/min. They are three modes on one jobsite machine, not one blended line speed.
    Is the shop arch-beam the same machine?
    Shop arch-beam is 10 stands, last-stand Ø110, ~10 m/min, feed 1200 mm, 0.8–1.5 mm. It is not 914→610 and not a K-span sew.
    How are price and lead time quoted?
    Send span, thickness, whether the work is jobsite K-span or shop beam. Commercial terms come back on the offer.
