Guardrail Spacer Block are considered as passive protectors with a view to ensure the safety of the pedestrians by the wayside and the vehicles. Highway guardrails are designed in pursuance to the principle of keeping the vehicle inside the road in a secure way and at the same time minimizing the loss of life and property in case of an accident.
It is mainly installed between guardrail and post to reduce the crash collision of highway/expressway/roadway.Spacer block itself is an energy absorbing part,so it could make the guardrail deform gradually during the sudden collisions.thus is conducive to energy absorption, reduce occupant casualties;at the same time,the spacer block could allocate the crash energy to guardrail and post,thereby increase the overall strength and tension of the guardrail system.
The most popular types of guardrail posts are C Type, U Type, H Type, UPN 120 Type, Box Type, Trapezoid Type and T Type.
