Galvanized guardrail panels are a continuous structure composed of corrugated steel guardrails interconnected and supported by main posts. The panels combine strength and flexibility, offering excellent collision energy absorption, good visibility guidance, and are aesthetically pleasing. They can be used on tight-radius curves and are easy to replace at damaged areas. The protective principle of galvanized guardrails involves utilizing the deformation of the soil foundation, posts, and crossbeams to absorb collision energy, forcing out-of-control vehicles to change direction and return to normal travel, preventing vehicles from veering off the road, thus protecting both vehicles and passengers, and reducing losses caused by accidents. When struck by a vehicle, the steel guardrails' good impact resistance and energy absorption properties make them difficult to be destroyed and provide excellent protection for the vehicle and occupants. In cases of road maintenance or other reasons requiring passage, the guardrail posts at the opening can be easily removed and moved to clear a path for vehicle traffic. Galvanized guardrail panels are made from high-quality steel plates that have undergone corrosion protection treatment, with the manufacturing process involving high-quality steel plates, zinc-plating, and spraying.
