PLC-Controlled Trapezoidal Metal Roof Panel Roll Forming Machine

This automatic trapezoidal roof panel roll forming machine converts metal coil into accurately profiled roofing and wall cladding sheets through a continuous cold-forming process. The equipment shown uses a rigid industrial frame, multi-stage forming stands, hydraulic cutting section, independent hydraulic power unit and elevated operator control station for convenient production monitoring.

The production line is suitable for roofing sheet manufacturers, steel structure contractors, prefabricated building factories, metal service centers and construction material suppliers. It can be engineered around a customer-supplied panel drawing to achieve the required effective width, rib height, rib pitch and sheet length.

Key Benefits

• Automatic coil-to-panel production with reduced manual handling.

• PLC control of sheet length, production quantity and batch settings.

• Precision rollers support consistent trapezoidal rib geometry.

• Hydraulic cutting provides efficient profile cutting after forming.

• Heavy-duty welded frame supports stable long-term production.

• Accessible operator panel simplifies setup and machine monitoring.

• Customizable forming stations, transmission and electrical components.

• Compatible with manual, motorized or hydraulic decoilers.

• Optional automatic stacker, protective film device and punching unit.

• Suitable for multiple coated steel and non-ferrous sheet materials.

Standard Production Process

Coil Loading → Decoiling → Feeding and Guiding → Leveling → Multi-Stage Roll Forming → Encoder Measuring → Hydraulic Cutting → Receiving or Automatic Stacking

Product Attributes and Customizable Specifications

Suitable Panel Applications

• Industrial factory and warehouse roofing

• Workshop and logistics center wall cladding

• Agricultural building and storage shed panels

• Prefabricated house and modular building envelopes

• Garage, canopy and commercial roofing sheets

• Steel structure roof and wall systems

• Metal building material production plants

Material Compatibility

The machine can be configured for pre-painted galvanized steel, galvanized steel, pre-painted Galvalume, Galvalume and aluminum. Final roller design and power selection depend on material thickness, yield strength, coating type, coil width and required panel profile.

Optional Line Equipment

Available options include a hydraulic decoiler, coil loading car, servo feeding unit, entry leveler, protective film laminator, hydraulic punching station, safety enclosure, automatic conveyor, pneumatic or servo stacker, inkjet printer and remote technical support module.

Customization Requirements

To prepare the correct machine configuration, customers should provide the finished panel drawing, effective width, overall width, rib height, rib pitch, raw coil width, material thickness, material grade, desired line speed, local electrical standard and required auxiliary equipment. The forming rollers and cutting dies will then be engineered for the target product.

Quality Control

Before delivery, the machine can be fully assembled and tested using suitable material. Feeding alignment, roller operation, panel geometry, encoder measurement, hydraulic cutting, PLC control and emergency functions are checked to support reliable installation and stable production.

After-Sales Support

Installation guidance, electrical diagrams, operating instructions, maintenance recommendations, spare parts support and remote troubleshooting are available. On-site commissioning and operator training can be arranged according to project requirements.
