Double layer roll forming machine

1. Machine Structure

The double layer roll forming machine is designed with a middle-plate welded frame that ensures high rigidity and stability during continuous production.
It integrates two layers of roll forming systems on one base:

• Upper layer: for producing trapezoidal sheets.

• Lower layer: for producing glazed roof tiles.
  This structure saves floor space and investment costs compared with two separate single-layer machines.

2. Working Principle and Function

The equipment automatically feeds, rolls, cuts, and outputs finished sheets according to preset programs.
By selecting the corresponding forming layer via the control panel, the operator can switch between two different profiles without changing rollers, ensuring flexible and efficient production.

3. Raw Material Compatibility

The machine is suitable for processing galvanized steel (GI), pre-painted steel (PPGI), aluminum, and other metal coils.
Standard material thickness ranges from 0.3 mm to 0.8 mm, width from 1000 mm to 1250 mm, meeting various roofing and wall cladding needs.

4. Transmission System

Equipped with a chain transmission system, the machine delivers stable power and reliable synchronization between rollers.
This simple yet efficient mechanism minimizes maintenance costs and is ideal for continuous operation in industrial environments.

5. Control System & Operation

The forming process is managed by an advanced PLC control system (with touchscreen interface), enabling automatic counting, length setting, and precision cutting.
Users can easily switch between profiles and adjust parameters without mechanical intervention, making operation intuitive and safe.

6. Applications

The double-layer roll forming machine is widely used for manufacturing roofing sheets for industrial buildings, residential houses, warehouses, carports, and workshops.
The trapezoidal profile is known for its strength and water resistance, while the glazed tile profile offers a decorative, elegant appearance.

7. Performance Advantages
