Hanging Plate
Open box beam guardrails are a type of guardrail used in highway safety systems that offer higher stiffness and impact resistance, making them suitable for special sections requiring higher crash performance ratings. Unlike traditional corrugated beam guardrails, open box beam guardrails feature a hollow rectangular cross-section steel beam structure. They are manufactured from high-quality hot-rolled steel plates through cold-forming and welding processes, resulting in a rectangular open-box cross-section. This unique design provides extremely high section modulus and bending stiffness, enabling the guardrail to effectively resist bending deformation caused by vehicle collisions, thereby significantly enhancing the system’s overall crash performance.

PRODUCT DESCRIPTION
Open box beam guardrails are a type of guardrail used in highway safety systems that offer higher stiffness and impact resistance, making them suitable for special sections requiring higher crash performance ratings. Unlike traditional corrugated beam guardrails, open box beam guardrails feature a hollow rectangular cross-section steel beam structure. They are manufactured from high-quality hot-rolled steel plates through cold-forming and welding processes, resulting in a rectangular open-box cross-section. This unique design provides extremely high section modulus and bending stiffness, enabling the guardrail to effectively resist bending deformation caused by vehicle collisions, thereby significantly enhancing the system’s overall crash performance.

The open box beam guardrails manufactured by our company strictly comply with international standards. We can provide zinc-aluminum-magnesium coatings or powder coatings (such as warning colors like yellow and green) according to customer requirements, with a service life of over 30 years in coastal or high-salt-fog environments. Due to their high rigidity, minimal deformation, and strong protective capabilities, open-box guardrails are particularly suitable for critical locations with extremely high requirements for guidance performance and structural stability, such as bridge sections, openings in median strips, lighting poles and pier protection zones, and ramp divergences. They represent an ideal protective solution for high-risk sections of expressways.
