Application Summary AI generated
This standard specifies the dimensions, materials, manufacturing processes, and performance requirements for three-wave corrugated steel beam guardrails used in road safety. It is applied in the design, production, and quality inspection of highway and expressway guardrail systems, particularly where higher impact resistance is needed compared to standard double-wave guardrails. The standard ensures consistent structural integrity and crashworthiness for roadside barriers in high-risk zones such as curves, bridges, and median dividers.
