| 1.1 Production Line | ||
| This ridge cap roll forming production line is designed for roofing accessory manufacturers, construction suppliers, and steel profile distributors. It provides stable performance, reduced floor space, and versatile customization. With features like folded edges, rib punching, and anti-rust design, it ensures higher product quality, safety, and durability for global roofing projects. |
| 1.2 Profile | |
| The ridge cap is made from galvanized or pre-painted steel, with thickness ranging from 0.3mm to 0.6mm. It features an arc-shaped profile with folded edges for safety and corrosion resistance. Rib embossing enhances strength and aesthetics. Widely applied in residential, commercial, and industrial roofing, it serves as both a protective and decorative component. | |
| 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: Decoiler → Guide → Roll forming machine → Hydraulic Punch → Hydraulic Cutter → Out table | |
| Process: The steel coil is guided into the roll former, where it is shaped into an arc ridge cap with folded edges. A hydraulic punching unit creates decorative or reinforcing ribs. The hydraulic cutter ensures precise length cutting. This process delivers uniform, durable, and aesthetically enhanced roofing ridge caps efficiently. |
| 1.4 Key Focus | |
| Folded edge design reduces sharpness and improves corrosion resistance. | |
| Rib punching enhances strength and decorative appearance. | |
| Portable hanging PLC screen saves floor space. | |
| Stable chain drive and wall frame structure ensure durability. | |
| Suitable for galvanized and pre-painted steel roofing applications. |
