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.
What is the service life of W‑beam highway guardrail?
The hot dip galvanized W‑beam guardrail can serve 15 to 20 years under regular outdoor conditions. Service life will decrease in coastal regions with heavy salt spray.
