In traffic engineering, highway crash barrier is aimed at preventing errant vehicles from hitting roadside obstacles which may be either man-made (sign structures, culvert inlets, utility poles) or natural (trees, rocks), running off the road and going down a steep embankment, or veering off the roadway into oncoming traffic (commonly referred to as a median barrier). 

Guardrail post, as a holder of highway guardrails, generally determines the barrier's performance during collisions. 

The Sigma Posts manufactured by Wuhan Dachu are well designed and made of high quality steel, such as Q235, A36 or depend on your needs.
