High Precision W Panel Roll Forming Machine for 3–4mm Galvanized Steel
These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.
1. Production Line Overview
This roll forming line is designed for highway guardrail manufacturers and metal profile suppliers in the road safety sector. It provides stable, high-precision W-beam production for heavy-duty applications. Ideal for companies seeking long-term performance, flexibility in thickness, and consistent panel quality using cold-rolled galvanized steel.
2. Profile Description
The W-beam guardrail profile is made from 3–4mm thick galvanized steel, with a two-wave curved structure. It offers high tensile strength, corrosion resistance, and is widely used for highway crash protection. The profile’s punching design ensures easy installation with bolts and posts on roads and bridges.
3. Production Process
7.5T Hydraulic Decoiler → Guiding Device → Powered Roller → Leveling Machine → Hydraulic Punching → Roll Former → Hydraulic Stop-to-Cut Cutter → Output Table
The line begins with coil decoiling, guiding, and assisted feeding via powered rollers. Leveling and punching share the same base with the roll former, optimizing space and alignment. Punching uses dual stations for efficient hole layout. The 18-station gearbox-driven roll former ensures high precision, ending with a hydraulic shear.
4. Technical Parameters
| Machine | Function & Highlights |
| 7.5T Hydraulic Decoiler | Feeds heavy steel coil into line |
| Hydraulic expansion ensures safe loading | |
| Guiding Device | Centers the coil for proper alignment |
| Powered Roller | Assists thick coil feeding into the forming line |
| Especially useful for 3–4mm thick material | |
| Leveling Machine | Flattens material before forming |
| Shares base with roll former for precise alignment | |
| Hydraulic Punching Unit | Dual station design improves punching efficiency |
| Integrated with roll former for compact layout | |
| Roll Former | Gearbox transmission ensures stability and strength |
| Chain drive suitable for thicker, heavy-duty materials | |
| 18 stations provide enough forming control for deep curves | |
| Hydraulic Cutter | Performs final cutting after forming is completed |
| Stop-to-cut system ensures cut accuracy and safety |
