Double Layer Roof Trapezoidal Sheet Roll Forming Machine
The Double Layer Roof Trapezoidal Sheet Roll Forming Machine is an advanced cold roll forming solution designed for manufacturing high-strength GI trapezoidal roofing panels. By integrating two roofing profiles into one compact production line, this equipment significantly improves factory space utilization and overall production efficiency.
Unlike traditional single-layer roofing sheet machines, this double-layer roofing sheet machine allows manufacturers to switch between two trapezoidal panel designs without investing in separate production lines. As a result, production flexibility increases while operational costs decrease.
Integrated Double Layer Roofing Sheet Machine Structure
This trapezoidal roof roll forming machine adopts a reinforced 400H steel frame and 80mm solid shafts to ensure long-term stability. The upper and lower forming stations operate independently yet share the same transmission system, enabling smooth profile switching.
Furthermore, the hard chrome-plated 45# steel rollers enhance durability and guarantee precise shaping of GI roofing sheets between 0.3–0.6mm thickness.
Because of its double-layer design, manufacturers can efficiently produce different metal roof panels for industrial buildings, warehouses, and commercial facilities.
Intelligent PLC Control & Hydraulic Cutting System
Equipped with an advanced PLC control system, this automatic roofing sheet making machine allows operators to set sheet length, quantity, and batch production directly from the touchscreen interface.
Meanwhile, the hydraulic cutting system made of Cr12Mov material ensures clean and deformation-free cutting. The integrated pulse encoder maintains high precision in length measurement, improving overall product consistency.
Additionally, the machine operates at a forming speed of 15–20m/min, depending on material thickness and panel profile. Therefore, it meets the demand for high-volume industrial roofing sheet manufacturing.

Application of the Trapezoidal Roofing Sheet Production Line
The roofing panels produced by this metal roof tile production line are widely used in:
- Large-span industrial factories
- Warehouses and logistics centers
- Commercial buildings
- Public facilities such as sports halls
- Solar photovoltaic roof systems
Because trapezoidal roof panels offer strong load-bearing capacity and excellent waterproof performance, they have become an ideal alternative to traditional roofing materials.
Why Invest in a Double Layer Roofing Panel Roll Former?
Compared with two single-layer machines, this double layer trapezoidal roofing sheet making machine:
- Reduces equipment investment cost
- Saves factory floor space
- Lowers labor requirements
- Decreases energy consumption
- Improves ROI cycle
Moreover, its modular design simplifies maintenance and extends equipment lifespan, making it a cost-effective choice for roofing sheet manufacturers worldwide.
