How C Purlin Roll Forming Works
The roll forming process for C purlins involves progressive shaping of a flat steel strip into a C-shaped profile.
Step-by-Step C Purlin Roll Forming Process
| Step | Description |
|---|---|
| 1. Decoiling | The metal coil is placed on the decoiler to feed the material. |
| 2. Leveling & Feeding | The sheet is straightened and guided into the forming stations. |
| 3. Punching & Cutting | The hydraulic system performs precise hole punching before forming. |
| 4. Roll Forming | The sheet passes through multiple roller stations, forming the C profile. |
| 5. Final Cutting & Output | The formed C purlin is cut to the required length and stacked. |
Pro Tip: A fully automated C purlin roll forming machine ensures higher accuracy and lower material waste.
