highway guardrail roll forming machine



The Highway Guardrail Roll Forming Machine manufactured by Hebei Xinnuo Roll Forming Machinery is not merely a piece of equipment; it is a critical instrument in the global advancement of transportation infrastructure. As the world expands its network of expressways, national highways, and complex interchanges, the demand for high-strength, crash-resistant road barriers has reached an all-time high. Our machinery is engineered to meet this demand, producing W-beam and Thrie-beam profiles that adhere to the most stringent international standards, including AASHTO M180, EN 1317, and various local metallurgical certifications.
At Hebei Xinnuo, we leverage decades of cold roll forming expertise to deliver a system that balances brute structural strength with microscopic precision. Every guardrail produced on our line is a testament to the "Xinnuo Standard"—a commitment to reliability that ensures the safety of millions of commuters worldwide. By integrating advanced hydraulic punching systems and state-of-the-art PLC automation, we provide a turnkey solution for manufacturers looking to dominate the industrial fencing and road safety market.

The longevity of a roll forming machine is determined by its core components. The Xinnuo Guardrail Machine utilizes GCR15 bearing steel for its rollers. Unlike standard carbon steel, GCR15 undergoes a rigorous vacuum quenching and tempering process to reach a hardness of HRC58-62. This ensures the rollers can withstand the immense pressure of forming 4.0mm thick steel without surface wear or profile distortion over years of operation.
Furthermore, the 40Cr solid shafts are precision-ground and CNC-machined to ensure perfect alignment. The machine base is constructed from 400H-beam heavy-duty welding, providing a rigid, vibration-free foundation. This structural mass is essential for maintaining consistent tolerances in the punching and cutting phases, preventing the "bow and twist" common in lighter, inferior machines.
Our production line operates as a synchronized, automated ecosystem. The process begins at the Hydraulic Decoiler, which handles coils weighing up to 10 tons. The material then passes through a 7-roller Leveling Device to eliminate internal stresses and coil set.
The most critical phase is the Multi-Die Hydraulic Punching Station. Our design allows for pre-punching of bolt holes and slots before the final profile is formed, which ensures that holes are perfectly aligned for easy assembly on-site. Following the punching, the material enters the forming stations, where the W-beam profile is gradually shaped through 20 stages of precision rolling. Finally, the Hydraulic Post-Cutting System uses a high-strength Cr12Mov blade to provide a clean, burr-free cut to the exact length specified in the PLC interface.
The products generated by this machine are the backbone of modern civil engineering. Beyond expressway guardrails, these W-beam profiles are essential for bridge railings, parking lot safety barriers, warehouse protection zones, and rural road safety upgrades.
Xinnuo Machinery has successfully exported these guardrail lines to over 70 countries, including significant installations in Southeast Asia, the Middle East, Africa, and Latin America. We understand the nuances of different climates, providing specialized anti-corrosion treatments for machines destined for humid or coastal environments.
Choosing Xinnuo means entering a partnership focused on long-term industrial success. We offer an industry-leading 2-year comprehensive warranty on all mechanical and electronic components. Our technical team provides detailed layout designs, foundation drawings, and remote video commissioning to ensure your operators are fully proficient within days of delivery.
