The highway corrugated guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrails spliced with each other and supported by columns.

The S-level guardrail is a reinforced type, which is suitable for use in particularly dangerous road sections on the roadside, and the A-level guardrail is used for special roads. The commonly used roadside corrugated beam guardrails can be divided into five grades: B, A, SB, SA, and SS according to the anti-collision level.
