| 1.2 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. Features include high structural strength, weather resistance, and aesthetic design. Suitable for roofing and cladding in industrial, commercial, and residential projects. Custom thickness and profile options available. | |
| Material: Galvanized Steel / PPGI / Aluminum | Thickness: 0.3-0.8mm |
| Yield strength: 200 - 350 Mpa | Tensil stress: 200 -350 Mpa |
| 1.3 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. |
| 1.4 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. |
