Our guardrail roll forming machine is an advanced, high-performance production line engineered for the continuous, accurate manufacturing of highway guardrail panels, three-beam guardrails, and other roadway safety profiles.
It efficiently converts steel coil feedstock into premium finished guardrails with uniform cross-sections, tight dimensional tolerances, and excellent structural strength. Built for reliability and productivity, this machine is a key solution for highway infrastructure projects, road safety product manufacturers, and metal fabrication facilities seeking consistent quality at scale.
Main Components
| Decoiler | Holds and feeds steel coils smoothly into the line |
| Leveling System | Ensures flat, uniform material before forming |
| Roll Forming Unit | Precision-engineered rollers shape steel into into different profiles with accuracy |
| Punching | The flat strip passes through the pre-punching station, where holes/slots are stamped out at precise intervals |
| Hydraulic Cutting System | Provides fast, clean, and burr-free cuts to required lengths |
| Control System (PLC + Touch Screen) | User-friendly interface for automatic operation and easy adjustments |
| Output Table | Collects finished products for efficient handling and packaging |
Key Features
1. High Automation & Efficiency
- Integrated design from decoiling, leveling, roll forming, punching to cutting.
- Fully automated PLC control system for seamless operation, minimal manual intervention, and high-volume output.
- Significantly reduces labor costs and increases production efficiency.
2. Exceptional Precision & Consistency
- Fabricated with high-strength alloy steel and precision-machined forming rolls.
- Ensures every meter of the guardrail maintains a consistent, accurate profile and precise dimensions, fully compliant with AASHTO, EN 1317, or other international standards.
3. Robust & Durable Construction
- Heavy-duty welded frame and reinforced structure ensure extreme stability and longevity, even under 24/7 continuous operation.
- Designed to handle high-tensile strength steel and long production runs.
4. Versatility in Production
- Capable of producing various guardrail profiles (e.g., W-beam, Thrie-Beam) and sizes by simply changing the forming roll sets.
- Can handle different material thicknesses (commonly from 2.0mm to 4.5mm) and coil widths as per project requirements.
5. Integrated Post-Forming Processes
- Pre-Punching System: Accurately punches bolt holes at pre-set intervals during the forming process.
- Flying Cut-Off System: Cuts the continuous rail to the exact required length without stopping the production line, ensuring clean and burr-free ends.
- Automatic Stacking: Optional automatic output rack for orderly collection of finished guardrails, preventing surface scratches.
6. User-Friendly Operation
- Centralised Human-Machine Interface (HMI) panel allows for easy parameter setting (length, quantity, etc.), operation monitoring, and fault diagnosis.
- Simple for operators to learn and manage.
