Output

What This Machine Produces

01

Thin ribbed or micro-rib wall panels in 0.3–0.5 mm — the normal specification for container conversions and modular buildings, because the container frame already carries the structural load and the panel only has to close the opening.

02

Deeper-rib roof panels for the same structures: the roof panel needs a deeper rib for spanning and water run-off, while the wall panel uses a shallower rib. Both run on the same frame with two cassettes.

03

Flat panels where a clean, unribbed face is wanted — the most demanding product on this line, because a flat surface shows every defect a rib would hide.

04

Insulated sandwich panel skins — where thermal performance is required, the single skin is replaced by an insulated sandwich panel, and this line forms the steel skins.

05

Panels in effective widths of 600–1100 mm at 15–28 m/min — one of the faster lines we build, because these are thin, simple sections.

06

Dimensionally consistent modules: because panels are cut to a fixed module size and assembled off-site, effective width has to hold. If it varies, modules do not line up and panels get re-cut on site, which destroys the time saving that makes modular construction worthwhile.

Line Composition

Recommended Configuration

A complete working line, not just the forming machine. Each item below is quoted as one package.

  1. 01

    Decoiler and leveling unit

    pre-painted coil at 0.3 mm marks easily, and a flat panel will show any leveling defect across its whole face.

  2. 02

    Container and modular panel roll forming machine

    12–18 stations on a gearbox chain drive at 5.5–11 kW, forming at 15–28 m/min.

  3. 03

    Polyurethane or nylon guide rolls

    we set roll pressure to the minimum that still forms the profile, which is what keeps the paint film intact on pre-painted panel.

  4. 04

    Two cassettes for wall and roof

    the rib depth differs between the two products, so they cannot share tooling, but the base frame, decoiler and cutting unit are common.

  5. 05

    Flying cut to length with batch counter

    modular panels are cut to module dimensions, so a whole module set is produced in one run.

  6. 06

    A word on thickness: 0.3 mm is the practical minimum. Below that the strip tends to buckle between stations and the finished panel shows oil-canning, which is visible on a flat or shallow-rib face.

How It Runs

Production Workflow

  1. 01

    Decoiler

    Coil is loaded and uncoiled at controlled tension. At 0.3–0.5 mm the material is very light, so over-tensioning is a common cause of edge wave.

  2. 02

    Leveling

    The strip is straightened at minimum pressure, because a heavier setting would mark the pre-painted surface.

  3. 03

    Roll forming

    12–18 stations form the ribbed, micro-rib or flat section at 15–28 m/min. Rib depth is the variable that distinguishes a wall panel from a roof panel on the same frame.

  4. 04

    Cassette change

    Wall and roof panels use different rib depths, so they run on separate cassettes on the common frame.

  5. 05

    Cutting

    A flying cut cuts to the module length with a batch counter.

  6. 06

    Output

    Panels leave on the runout, bundled by module so the off-site assembly sequence is respected. For a small modular builder, 15–20 m/min is ample — roughly 600–800 m of panel per shift, which supports several modules a day.

Common Questions

FAQ — Container & Modular Wall Panel Roll Forming Machine

What panel is used on container conversions?
Mostly thin ribbed or micro-rib panels in 0.3–0.5 mm, because the container frame already carries the structural load and the panel only has to close the opening. Where thermal performance is needed, an insulated sandwich panel replaces the single skin.
Can the machine produce both wall and roof panels for a container?
Yes. The roof panel normally has a deeper rib for spanning and water run-off, the wall panel a shallower rib. Both can run on the same frame with two cassettes.
Why is dimensional consistency important for modular buildings?
Because panels are cut to a fixed module size and assembled off-site. If the effective width varies, the modules do not line up and the panels have to be re-cut on site, which destroys the time saving that makes modular construction worthwhile.
What is the minimum thickness you can run?
0.3 mm is the practical minimum. Below that the strip tends to buckle between stations and the finished panel shows oil-canning.
Can it form pre-painted panels without marking?
Yes. We use polyurethane or nylon guide rolls and set roll pressure to the minimum that still forms the profile, which keeps the paint film intact.
What output rate is typical?
For a small modular builder, 15–20 m/min is ample — roughly 600–800 m of panel per shift, which supports several modules per day. Higher speeds mainly suit panel wholesalers.
Can the machine be built for our own profile?
Yes. Send the profile drawing with the section dimensions, the material and thickness, and the coil width you intend to run. We confirm the roll design, forming stations and line layout against that drawing before quoting, so the machine matches the section you actually sell.
How do we get a price for this line?
Send the profile drawing or section dimensions, the material and thickness, the coil width, and your target output per shift. Price depends on the profile, the coil and the level of automation, so we quote against your actual job rather than a catalogue figure.
Which coil materials can the line run?
The line forms PPGI, GI, aluminium. Confirm the exact grade with your order so the tooling and drive are matched to it — that is decided at the design stage, not on site.
How many forming stations does it use?
The line uses 12 – 18 forming stations. Station count follows the section — more bends and tighter tolerances need more forming steps, which is why two profiles rarely share one roll set.
What is the drive and installed power?
Drive: Gearbox chain drive, 5.5 – 11 kW. Final drive sizing is confirmed against your profile and coil, because a wider or thicker section needs more torque to hold the same line speed.
How is the finished profile cut to length?
Cutting is by Flying cut to length. Cut length and batch quantity are entered at the control panel, so a job runs to a fixed schedule instead of being measured by hand.
