    1. Definition

    A U channel roll forming line cold-forms coil into structural U / channel sections for building and industrial use. Chain, gearbox, flying-saw, and twist-off packages are configuration tiers of the same family — not separate product lines.

    This page covers structural U channel duty. It is not a light-gauge “CU combined light keel” drywall machine.

    2. Typical process flow

    1. Decoil
    2. Level / feed
    3. Punch (when required)
    4. Roll form the U section
    5. Flying saw or other cut-off
    6. Exit / collect

    3. Technical parameters (flying-shear class)

    One documented flying-shear reference package uses the following baseline. Gearbox and twist-off packages differ — see next section.

    ItemTypical value
    ThicknessAbout 2.0–3.0 mm
    Material contextQ215 / Q235 / Q345 class; yield strength about 195–350 MPa
    Forming speed (this class)About 8–10 m/min
    Forming stationsAbout 12
    Shaft diameterAbout φ80 mm
    Main drive powerAbout 11 kW
    Flying-saw motorAbout 15 kW
    Hydraulic stationAbout 3 kW (punch hydraulics may add a similar class pump)
    Host envelope (approx.)About 6800 × 800 × 1200 mm, about 6.2 t; frame about 400H

    4. Other configuration tiers

    • Gearbox class — may cite about 30 m/min; do not merge with the flying-shear 8–10 m/min figure as one “standard speed”
    • Twist-off cut — alternate cut-off package on the same U-channel family
    • Controls on the flying-shear reference cite Mitsubishi PLC with Schneider-class low-voltage components; other brands appear on other contracts

    Market U-channel / U-purlin pages often advertise about 1.5–3.0 mm and various chain or flying-cut packages — industry context only, not a substitute for the named tier above.

    5. Related machines

    • C purlin line — Cee structural purlins with lips; different roll set
    • Z purlin / C/Z interchangeable — separate inquiries
    • Light-gauge CU / stud-track — thinner interior framing; SKIP for this structural U path
    • Strut channel (41×41 class, etc.) — specialized support channel; confirm drawing before assuming it is the same U mill

    6. Applications

    Structural U / channel sections for industrial and civil building packages — exact section geometry follows the contract drawing.

    7. Buyer FAQ

    Is 30 m/min the normal speed?

    Only on gearbox-class packages. Flying-shear references sit around 8–10 m/min. Ask which cut-off tier is quoted.

    Same as a C purlin machine?

    No. Different section and tooling.

    Same as drywall track / light keel CU?

    No. Those light-gauge packages must not donate thickness or power numbers to this page.

    Final ratings follow the confirmed technical proposal for the named cut-off tier. Price and lead time are out of scope.
