The most prominent feature of this guardrail is its integrated active-passive protection system, which combines millimeter wave radar with 120° wide-angle AI image recognition to achieve 24/7 real-time monitoring with a response time of less than 0.3 seconds, ensuring timely warnings even in complex weather conditions such as heavy rain, fog, or night. Constructed with Q355 high-strength weather-resistant steel, it offers excellent corrosion resistance and impact resistance, meeting the ASTM A653 standard for structural steel. The dual-power supply system (30W solar panel + 100Ah lithium battery) supports continuous operation for over 15 days without sunlight, and the modular bolt splicing design allows for flexible adjustment of guardrail length to adapt to different road shapes. With an IP67 protection grade, it can withstand extreme temperatures ranging from -40°C to +70°C, making it suitable for various harsh outdoor environments. Additionally, it provides data transmission functions, allowing traffic management departments to remotely monitor road conditions and accident risks, optimizing traffic scheduling and emergency response strategies.
The Intelligent Early-Warning Anti-Collision Guardrail adopts a modular structure, with each standard section measuring 2 meters in length and 0.8 meters in height. The main guardrail panel is made of 6mm thick Q355 high-strength weather-resistant steel, while the supporting columns are 150mm in diameter with a wall thickness of 5mm, buried 0.8 meters deep into the ground for stable support. The millimeter wave radar has a detection range of 50-200 meters with adjustable sensitivity, and the AI image recognition module uses an 8MP high-definition camera with a 120° viewing angle to capture clear images of vehicle behaviors. The solar panel has a power output of 30W, paired with a 100Ah lithium iron phosphate battery that provides backup power for up to 15 days. The guardrail surface is coated with a powder coating with a thickness of 80μm, offering excellent UV resistance and corrosion resistance. It complies with ISO 14001 environmental management standards, and its impact resistance reaches up to 100kN, effectively absorbing collision energy to reduce vehicle and driver damage.
This product is primarily applicable to high-risk sections of expressways and first-class highways, including curved sections, long downhill slopes, tunnel entrances and exits, bridge approaches, and accident-prone areas with a history of frequent rear-end collisions. It is also suitable for temporary use in highway construction sections to guide traffic and prevent secondary accidents. For traffic management departments, it provides real-time data on vehicle behaviors and accident risks, enabling proactive traffic control and emergency response. For highway operation companies, its modular design reduces installation and maintenance costs, while its long service life (≥15 years) lowers the total cost of ownership. In addition, it can be used in urban expressways and ring roads with high traffic volume to improve traffic safety and reduce accident rates. By combining active warning and passive protection, it creates a multi-layered safety barrier that protects both drivers and road infrastructure.
