Automatic Trapezoidal Roof Panel Production Line with PLC and Hydraulic Cutting

This industrial roll forming line continuously converts metal coil into precisely shaped trapezoidal roofing and wall cladding panels. The machine shown features a rigid welded base, multiple supported forming stations, chain transmission, hydraulic profile cutting, an independent hydraulic power unit with cooling and a suspended HMI control panel for convenient operation.

The equipment is suitable for roofing sheet factories, steel structure companies, prefabricated building manufacturers, metal service centers and construction material suppliers. The complete line can be designed according to a customer-supplied profile drawing so the effective width, total width, rib height, rib pitch, overlap and finished sheet length match the target market.

Key Advantages

• Automatic coil-to-panel production reduces labor and handling.

• PLC control supports programmable length, quantity and batch production.

• Precision roller tooling helps maintain stable rib geometry.

• Hydraulic cutting provides efficient finished-length processing.

• Heavy-duty frame supports long-term industrial operation.

• Suspended HMI station provides convenient access and clear monitoring.

• Adjustable feeding guide helps improve coil alignment.

• Custom tooling is available for different trapezoidal profiles.

• Compatible with manual, motorized and hydraulic decoilers.

• Optional film laminator, punching unit, conveyor and automatic stacker.

Production Process

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

Product Attributes and Customizable Specifications

Typical Applications

• Industrial factory roofing sheets

• Warehouse and logistics center wall cladding

• Workshop roof and siding panels

• Agricultural sheds and storage buildings

• Prefabricated and modular building envelopes

• Garage, canopy and commercial roofing

Compatible Materials

The line can be configured for pre-painted galvanized steel, galvanized steel, pre-painted Galvalume, Galvalume and aluminum coil. Final roller design, forming station quantity, drive power and cutting configuration depend on sheet thickness, yield strength, coating type, coil width and the required panel profile.

Optional Line Equipment

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

Customization Information Required

For an accurate machine proposal, customers should provide the finished panel drawing, effective cover width, overall width, rib height, rib pitch, side lap geometry, raw coil width, material thickness, material grade, desired production speed, local electrical standard and required auxiliary equipment.

Quality Control and Pre-Shipment Testing

Before shipment, the machine can be fully assembled and tested with suitable material. Coil feeding, roller alignment, profile geometry, transmission operation, encoder measurement, hydraulic cutting and PLC functions are checked to support reliable installation and stable production.

Installation and 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.
