What This Machine Produces
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.
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.
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.
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.
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.
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.
Recommended Configuration
A complete working line, not just the forming machine. Each item below is quoted as one package.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Production Workflow
- 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.
- 02
Leveling
The strip is straightened at minimum pressure, because a heavier setting would mark the pre-painted surface.
- 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.
- 04
Cassette change
Wall and roof panels use different rib depths, so they run on separate cassettes on the common frame.
- 05
Cutting
A flying cut cuts to the module length with a batch counter.
- 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.

|---|---|
| Profile set | Wall panel, roof panel, micro-rib, flat, or sandwich panel skin |
| Effective width | 600–1100 mm |
| Thickness | 0.3–0.5 mm typical for container conversions; 0.3 mm is the practical minimum before oil-canning appears |
