    Multi-Layer Roof Sheet Forming Line

    A triple mill is three roll sets in one frame; one deck runs. Unique thickness, speed and power wait for your three drawings. Dual-layer neighbours stay labeled as two-deck machines.

    What this process looks like

    A triple mill is three roll sets in one frame. Shared decoiler, cut, PLC. This catalogue names the machine and does not lock a unique thickness, speed or power. Dual-layer numbers below are neighbours only.

    Which deck is which. Thickness often differs — dual-layer already splits corrugated vs trapezoid.

    Clutch, handle or hydraulic shift. Two decks on a shared drive only if the proposal says so.

    Speed waits. Dual-layer 5.5 kW or 18.5 kW numbers stay off a triple nameplate.

    Key details

    Live deck tagged

    Upper / mid / lower matches the first sheet.

    Thickness per profile

    One blended gauge for three flowers fails the quote.

    Dual-layer stays two-deck

    5.5 kW / 18.5 kW / 220 V tile are other machines.

    FAQ

    Is there a standard triple-layer kilowatt?
    Not on a unique nameplate in this catalogue. Send three finished profiles and thickness per profile. Dual-layer 5.5 kW or 18.5 kW numbers stay on two-deck hosts.
    Can two decks run at once?
    Typical designs run one live deck. Clutch, handle or hydraulic shift selects it. Two decks on a shared drive only if the proposal says so.
    How are price and lead time quoted?
    Send three profiles, thickness per profile, cut type and site voltage. Commercial terms come back on the offer.
