Galvanized steel guardrail panels are the primary form of semi-rigid guardrails. They consist of a continuous structure with corrugated steel panels joined together and supported by posts. These panels combine strength and flexibility, harmonize with road contours, are aesthetically pleasing, can be used on tight-radius curves, and are easy to replace at damaged sections.
It absorbs collision energy by utilizing the deformation of the soil base, pillars, and beams, forcing out-of-control vehicles to change direction back to the normal driving path, preventing the vehicle from veering off the road, and protecting the vehicle and passengers, thereby reducing the losses caused by accidents.
