Double-Layer Roofing Roll Forming Machine for Corrugated and Great Wall Style Roof Panels with PLC Control
Overview
Production Line
This double-deck roll forming production line serves roofing panel manufacturers seeking flexible, high-efficiency solutions. Ideal for industrial and commercial clients, it produces corrugated and trapezoidal roof panels with precision.
- Multi-profile production capability
- Dual-layer output for increased productivity
- Space-saving design for efficient factory layout
- Durable chain drive system
- Operator-protective features for workplace safety
Profile
Corrugated and Great Wall trapezoidal roof panels are produced from 0.4-0.8mm galvanized or color-coated steel. The upper layer forms corrugated sheets, lower layer trapezoidal sheets.
| Material |
Galvanized Steel / PPGI / Aluminum |
| Thickness |
0.3-0.8mm |
| Yield strength |
200 - 350 Mpa |
| Tensile stress |
200 -350 Mpa |
Production Process
Flow Chart: Hydraulic Decoiler → Entry Guide → Roll Former → Hydraulic Cutter → Out Table
Process: Steel coils are fed and aligned, then simultaneously formed into two roof panel profiles by the double-deck roll former. Chain drive ensures stable, precise forming. Upper deck produces corrugated panels, lower deck trapezoidal panels. Hydraulic cutter trims panels to length. Out tables collect finished panels for inspection and packaging.
Key Focus
- Dual-layer design enables production of multiple roof panel profiles simultaneously
- Chain-driven, covered system ensures operator safety and reduces maintenance
- Flexible panel dimensions increase market adaptability
- High precision forming improves panel quality and structural strength
- Space-efficient design minimizes factory footprint while maximizing output
