Profile Information
Highway guardrail W beam barriers absorb vehicle impact energy and improve roadside safety. Their corrugated wave-shaped design provides excellent strength, flexibility, and crash resistance.
Widely used in North America, South America, the Middle East, and Asia, highway guardrail beam barriers are commonly produced from galvanized steel by a highway guardrail w beam roll forming machine.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler+Leveler
The decoiler and leveling machine continuously feed steel coils into the roll forming machine. The leveling section removes coil stress and surface deformation, ensuring stable feeding accuracy and smooth profile forming quality.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Hydraulic punching unit
The servo feeder accurately controls feeding length and synchronizes material movement with the hydraulic punching unit. The hydraulic punching system creates precise mounting holes and slot patterns required for highway guardrail installation, ensuring dimensional consistency and efficient downstream roll forming production.
Transport Table
The transport table transfers pre-cut sheets into the roll forming machine continuously, allowing punching and pre-cutting operations without stopping the main forming section during production.
Roll forming machine
This highway guardrail w beam roll forming machine adopts cast-iron stands and a gearbox driving system for heavy-duty continuous production. Because guardrail material is thick and already punched, the forming machine requires higher rigidity, stronger transmission stability, and precise roll forming performance to prevent profile deformation.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Auto stacker
Finished highway guardrail beams are typically 3-4 meters long and extremely heavy. The auto stacker reduces manual handling, improves production safety, increases collection efficiency, and keeps finished products neatly organized after roll forming.
| Item | Out Table | Auto Stacker |
| Type | Manual / Semi-manual | Fully automatic |
| Investment | Low cost | Higher initial investment |
| Labor | Requires manual handling | Reduces labor significantly |
| Efficiency | Suitable for low–medium speed | Ideal for high-speed production |
| Flexibility | High | Moderate |
| Stacking | Manual, less consistent | Automatic, neat and consistent |
| Maintenance | Simple | More complex |
| Application | Small to medium production lines | Large-scale, continuous production |
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
The standard configuration operates at 15–20 m/min. Higher-end configurations can reach 30–40 m/min, and even higher speeds can be customized according to specific production requirements.
Lead times range from 40-60 days post-order, varying by customization level and supplier location. We typically require 50 days for standard machines.
For heavy and long highway guardrail products, the auto stacker significantly reduces labor intensity, improves safety, and increases production efficiency during continuous roll forming production.
Yes. We are a professional manufacturer that produces both standard market profiles and customized profiles. We can also sign an agreement to ensure that your drawing will not be shared with other parties.
