Heavy-Duty Automatic Trapezoidal Roofing Sheet Roll Forming Line

This industrial roll forming line converts coated or uncoated metal coil into accurate trapezoidal roofing and wall cladding profiles. The machine is engineered for repeatable panel geometry, efficient continuous production and convenient operation. Its visible configuration includes a rigid welded base, multiple forming stands, hydraulic cutting section, hydraulic power unit and a movable operator control station.

The line can be customized according to the customer’s panel drawing, effective cover width, rib height, rib pitch, raw material, thickness range, production speed and local electrical standard. It is suitable for manufacturers serving industrial buildings, warehouses, agricultural structures, workshops, garages and modular construction projects.

Main Features

• Automatic coil-to-panel production with PLC-based operation.

• Precision roller forming for stable trapezoidal rib shape.

• Programmable panel length, batch quantity and production count.

• Hydraulic profile cutting for efficient finished-length processing.

• Heavy-duty welded steel frame for industrial production.

• Operator-friendly control panel with emergency stop and manual functions.

• Adjustable feeding guide for accurate coil entry.

• Custom roller tooling based on the required roof panel drawing.

• Optional decoiler, coil car, film device, punching unit and stacker.

• Suitable for a wide range of roofing and wall cladding materials.

Production Flow

Coil Loading → Decoiling → Feeding and Guiding → Leveling → Continuous Roll Forming → Length Measuring → Hydraulic Cutting → Panel Receiving or Automatic Stacking

Product Attributes and Technical Options

Suitable Applications

• Industrial factory and warehouse roofing

• Workshop and logistics center wall cladding

• Agricultural sheds and storage buildings

Optional Equipment

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

Customization Information Required

For an accurate machine proposal, please provide the finished panel drawing, effective cover width, overall width, rib height, rib pitch, raw coil width, material thickness, material grade, desired production speed, local power supply and required auxiliary equipment. The roller tooling and cutting dies will be designed around these requirements.

Quality Control and Testing

Before shipment, the machine can be fully assembled and tested with suitable material. Feeding alignment, roller operation, panel geometry, encoder measurement, hydraulic cutting, PLC functions and safety controls are checked to support stable installation and production.

Service Support

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