Touchscreen Automatic Trapezoidal Roof Sheet Roll Forming Line

This automatic roll forming line converts flat metal coil into accurately shaped trapezoidal roofing and wall-cladding sheets through a continuous cold-forming process. It is suitable for manufacturers supplying industrial buildings, warehouses, workshops, agricultural structures, prefabricated houses, garages, carports and commercial construction projects.

The machine shown features a heavy welded frame, precision forming stations, an independent hydraulic power unit, a profile-matched cutting assembly and an elevated touchscreen control console. The progressive forming sequence helps control strip stress, preserve coated surfaces and maintain consistent rib geometry, effective cover width and finished panel length.

Key Advantages

• Automatic production from guided coil feeding to fixed-length cutting

• PLC and touchscreen control for length, quantity, speed and batch settings

• Encoder-based measurement for repeatable finished-panel dimensions

• Rigid welded frame for stable continuous industrial operation

• Hydraulic profile cutting for clean and accurate panel ends

• Custom roller tooling for different trapezoidal roof profiles

• Suitable for galvanized, Galvalume, color-coated steel and aluminum coils

• Expandable with decoiling, leveling, punching, stacking and packaging systems

Typical Product Attributes and Technical Configuration

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

Production Workflow

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

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

3. Progressive forming: Multiple roller stations gradually create the ribs, valleys and side-lap edges.

4. Electronic measurement: The encoder measures sheet travel and sends real-time length data to the PLC.

5. Hydraulic cutting: The profile-matched cutter operates when the programmed panel length is reached.

6. Receiving and stacking: Finished panels move to run-out tables or an optional automatic stacking system.

Typical Applications

The finished panels are widely used for industrial workshop roofs, warehouse walls, logistics centers, agricultural sheds, commercial buildings, garages, carports, prefabricated houses, modular buildings, temporary structures and general steel-structure construction.

Optional Line Configurations

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

• Hydraulic decoiler with coil car and entry leveling unit

• High-speed line with servo tracking or flying-cut technology

• Inline punching, marking and production-data recording

• Double-layer machine for two roof profiles on one frame

• Automatic stacking, counting, strapping and packaging system

Information Required for Custom Engineering

Please provide the finished-panel drawing, raw-material type, material grade, thickness range, input coil width, effective cover width, rib height, rib pitch, required line speed, preferred cutting method, local voltage and desired auxiliary equipment. These details allow the roller tooling, shaft load, motor power and control strategy to be matched to the actual production requirement.

Quality Control and Factory Testing

Before shipment, the complete line is assembled, aligned and test-run. The forming sequence, shaft alignment, transmission operation, hydraulic pressure, cutting action, encoder measurement, PLC program and finished sample dimensions are checked against the approved technical specification.

Maintenance Recommendations

• Clean forming rollers and remove metal particles after production.

• Lubricate bearings, chains, gears and guide components regularly.

• Check hydraulic oil level, hoses, filters and pressure settings.

• Verify cutting-blade clearance when changing material thickness or grade.

• Keep the electrical cabinet clean, dry and properly ventilated.

• Inspect fasteners, transmission alignment and safety devices periodically.

Service and Support

TOPPO provides remote installation guidance, commissioning assistance, operator training, maintenance recommendations and spare-parts support. Optional on-site engineering service can be arranged according to the project destination and contract terms.
