How Highway Guardrail Roll Forming Works
The roll forming process for guardrails involves gradually shaping a flat steel coil into a high-strength guardrail profile.
Step-by-Step Highway Guardrail Roll Forming Process
| Step | Description |
|---|---|
| 1. Decoiling | The steel 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 hole punching for guardrail installation. |
| 4. Roll Forming | The sheet passes through multiple roller stations, forming the guardrail shape. |
| 5. Final Cutting & Output | The formed guardrail is cut to the required length and stacked. |
👉 Pro Tip: A fully automated guardrail roll forming machine ensures high precision, minimal waste, and faster production speeds.
