Profile Information
Highway guardrail U posts and block spacers are widely used in road safety barrier systems for supporting and spacing guardrails. Their U-shaped structure provides high strength, impact resistance, and installation stability.
These profiles are popular in North America, South America, the Middle East, and Southeast Asia, commonly produced from galvanized steel using a highway guardrail U post roll forming machine.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler+Leveler
The decoiler feeds steel coils smoothly into the roll forming machine, while the leveling machine removes coil stress and surface curvature through multiple rollers to improve forming precision and punching consistency.
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 5/7/10 Ton | Expanding Range | 460-50mm |
Punching unit
The hydraulic punching unit creates mounting holes before roll forming for lower tooling cost and easier punching operation on the web area. Its compact connection with the roll forming machine saves factory space, although production speed is relatively slower due to synchronized stop-and-punch operation.
Roll Forming Machine
This roll forming machine uses cast-iron stands and a gearbox driving system to handle thick steel material with punched holes reliably.
Multiple roller stations gradually form the profile while maintaining dimensional accuracy, structural strength, and long-term machine stability during heavy-duty production.
| 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 |
Hydraulic cutting unit
The hydraulic cut adopts a stop-to-cut design, allowing stable and accurate cutting by temporarily stopping profile movement during cutting. For customers requiring higher production speed, customized flying cut solutions are also available.
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 30-40 days post-order, varying by customization level and supplier location. We typically require 35 days for standard machines.
Yes. If the U post and block spacer share similar dimensions and section structures, the roll forming machine can usually produce both profiles with roller adjustments.
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.
There is no need to worry. Our machines are designed for easy installation and operation.
Before shipment, we will finish the main assembly and testing in our factory. When the machine arrives, you only need to place it in position, connect the power supply, and it can start working.
We will also provide:
detailed installation and operation manuals
machine layout drawings
wiring diagrams
online technical support (video call / photos / videos)
If needed, we can also arrange an engineer to come to your factory to help with installation and training. Many of our customers complete installation smoothly with our online guidance.
