This automatic roll forming line continuously converts metal coil into precisely shaped trapezoidal roofing and wall cladding panels. The machine shown features a heavy-duty welded base, supported forming stands, hydraulic cutting section, independent hydraulic power unit and a suspended operator control panel for convenient parameter setting and production monitoring.
It is suitable for roofing sheet manufacturers, steel structure companies, prefabricated building factories, metal service centers and construction material suppliers. The complete line can be designed according to the customer’s exact panel drawing, including effective cover width, overall width, rib height, rib pitch, overlap geometry and finished sheet length.
Automatic coil-to-panel production reduces manual handling.
PLC control supports programmable length, quantity and batch settings.
Precision roller tooling helps maintain consistent rib geometry.
Hydraulic profile cutting provides efficient finished-length processing.
Heavy-duty frame supports stable long-term industrial production.
Suspended HMI station improves operator access and visibility.
Adjustable feeding guide helps improve coil alignment.
Custom roller tooling is available for different trapezoidal profiles.
Compatible with manual, motorized and hydraulic decoilers.
Optional film laminator, punching system, conveyor and automatic stacker.
