| 1.1 Production Line | ||
| This roll forming production line targets roofing manufacturers and construction companies. It delivers high-quality half round ridge caps with folded edges and ribbing. Advantages include precise dimensions, efficient production, anti-corrosion edges, and adaptability for various roofing projects, ensuring aesthetic and structural quality. |
| 1.2 Profile | |
| The ridge cap is made from galvanized or pre-painted steel, thickness 0.4–0.8mm, featuring a half-round curved shape. Folded edges improve safety and corrosion resistance, while rib embossing enhances strength. Ideal for residential, commercial, and industrial roofs, providing durable, aesthetic, and high-quality roofing finishing solutions. | |
| 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: The steel coil is fed into the roll former, where the curved half-round ridge shape is continuously formed. Folded edges are shaped simultaneously, reducing sharpness and protecting coatings. Hydraulic punching creates ribs for strength and aesthetics. Hydraulic cutting ensures precise length, while the out table collects finished ridge caps efficiently. |
| 1.4 Key Focus | |
| High precision roll forming ensures consistent ridge cap dimensions and curvature. | |
| Folded edges reduce material sharpness and enhance corrosion resistance. | |
| Rib embossing strengthens ridge caps and improves aesthetic appeal. | |
| Chain-driven roll former with wall plate structure ensures long-term stability. | |
| Hydraulic punch and cutter provide fast, accurate processing for custom lengths. |
