Industrial Trapezoidal Metal Roof Panel Roll Forming Machine

This industrial roll forming line is engineered to convert flat metal coil into accurate trapezoidal roof and wall panels in a continuous production process. The system is suitable for manufacturers serving steel-structure buildings, warehouses, workshops, agricultural facilities, commercial projects and prefabricated construction.

The machine shown uses a heavy welded frame, precision forming stands, a hydraulic cutting unit, an independent hydraulic power station and a movable PLC operator console. A progressive forming sequence helps control material stress, preserve coated surfaces and maintain consistent rib shape, panel width and cut length.

Key Features

• Automatic operation from coil feeding to finished panel cutting

• PLC control with touchscreen production-data setting

• Encoder-based length measurement and automatic batch counting

• Rigid frame and closely supported forming stations for stable production

• Hydraulic profile cutter for clean and repeatable panel ends

• Custom roller tooling for different trapezoidal roof profiles

• Compatible with common coated steel and aluminum coil materials

• Expandable with decoilers, leveling, punching, stacking and packing systems

Typical Technical Attributes

Notice: The values below are typical references. Final specifications are confirmed according to the approved panel drawing, material grade, thickness range, target speed and local electrical standard.

Production Workflow

1. Coil loading: The coil is loaded onto the decoiler and aligned with the production line.

2. Guided feeding: Adjustable guides center the strip before forming.

3. Progressive forming: Multiple roller stations gradually produce the trapezoidal profile.

4. Length control: The encoder sends real-time length data to the PLC.

5. Hydraulic cutting: The profile cutter operates at the programmed length.

6. Receiving: Finished panels move to support tables or an automatic stacker.

Typical Applications

Finished panels are used for industrial roofs, warehouse walls, workshops, logistics facilities, agricultural sheds, garages, carports, prefabricated houses, modular buildings and general steel-structure construction.

Optional Line Configurations

• Manual decoiler, roll former, hydraulic cutter and receiving tables

• Hydraulic decoiler with coil car and leveling unit

• High-speed line with servo tracking cut

• Inline punching and marking system

• Double-layer machine for two profiles

• Automatic stacking, counting and packaging line

Customization Information

For accurate engineering, please provide the finished panel drawing, material type, grade, thickness range, input width, effective cover width, rib height, rib pitch, required speed, cutting method, local voltage and desired auxiliary equipment.

Quality Control

Before shipment, the complete line is assembled and test-run. Roller alignment, drive operation, hydraulic pressure, cutting action, PLC program, encoder measurement and sample-panel dimensions are checked against the approved specification.

Maintenance and Service

Routine maintenance includes cleaning the forming rollers, lubricating bearings and transmission parts, checking hydraulic oil and filters, verifying blade clearance and keeping the electrical cabinet dry and ventilated. TOPPO provides remote commissioning support, operator training, spare-parts service and optional on-site assistance.
