Characteristics that must be possessed by the safety performance of guardrail beam

Firstly, guardrail beam should have sufficient strength and stiffness to withstand the impact force of vehicle collisions, prevent vehicles from crossing or collapsing through guardrail beam and thus avoid the occurrence of secondary accidents.

Secondly, guardrail beam should have good energy absorption performance, which can absorb the kinetic energy of vehicle collisions and reduce injuries to vehicles and passengers.

In addition, guardrail beam should also have good line of sight guidance function, which can coordinate with the road alignment, provide clear driving direction indications, and reduce driver fatigue and misunderstandings.
