Profile Information
Highway guardrail W beam barriers absorb collision impact and redirect vehicles safely through their wave-shaped structural design. They are widely used on highways, bridges, and roadside protection systems.
Popular in North America, South America, the Middle East, and Southeast Asia, highway guardrail beam barriers are usually produced from galvanized steel by a highway guardrail w beam roll forming machine.
How Does The Roll Forming Machine Work?
Machine Details
Decoiler And Leveling Machine
The decoiler continuously feeds steel coils into the leveling machine, where multiple rollers eliminate coil stress and improve flatness before punching and roll forming machine processing.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Servo Feeder And Punch Press
The servo feeder accurately controls feeding length for precise hole positioning, while the punch press performs continuous heavy-duty punching with high efficiency and long-term stability. Pneumatic punching or hydraulic punching can be optional lower-configuration solutions for lower production demands.
Transport Table
The transport table buffers punched sheets between pre-cutting and the roll forming machine, allowing continuous feeding without stopping the forming section during hydraulic pre-cut operation.
Roll Forming Machine
This highway guardrail w beam roll forming machine adopts cast-iron stands and a gearbox driving system for superior rigidity and transmission stability. Since guardrail beams use thick punched steel coils, the heavy-duty structure effectively reduces vibration, maintains forming precision, and improves long-term production reliability.
| 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 |
Convyor
Because highway guardrail beam products are usually 3–4 meters long and extremely heavy, the auto stacker greatly reduces manual labor, improves stacking efficiency, and minimizes profile scratching during collection.
| 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 |
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.
