Spacer
The main function of a guardrail spacer is to prevent the wheels of a colliding vehicle from snagging on the guardrail posts. Applying spacer provides a significant improvement to the safety of W-beam guardrail by maintaining its geometry during impact.
Surface finish A road safety barrier system shall have a surface finish that minimizes the friction between the system and an impacting vehicle. The surface finish shall be uniform, resistant to incidental damage and shall not be affected by detergents and similar agents that may be used to clean the external surfaces. Protrusions from the surface, which are likely to be struck by an impacting vehicle, shall not exceed 20 mm. Any protrusions shall be rounded or similarly treated, to reduce the possibility of snagging the body work of a vehicle or catching at the person or clothing of an individual. After construction, components shall not be left with splits, burrs or sharp edges after construction. Lapping of elements shall be in the direction of the potential path of an errant vehicle.
