How are guardrail materials configured per kilometer?
Layout Reference for One Kilometer Highway Guardrail Installation
For standard W-beam highway guardrail sections, steel posts are arranged with four meters center-to-center spacing for regular road segments.
One kilometer of standard guardrail requires the following components.
250 pieces of W-beam guardrail plates, 251 steel posts, 250 spacer blocks or brackets, 250 post caps, 250 sets of M16×170 bolts, 2000 sets of M16×40 bolts, 250 sets of M16×50 bolts, 250 beam gaskets and two R160 end terminals.
For high risk reinforced sections, we apply a two-meter post spacing layout to deliver enhanced anti-crash performance to match local highway design requirements.
