Hydro high capacity sign posts

In addition to Hydro's crash-friendly aluminium lighting columns and traffic signal poles, we also offer aluminium sign posts. These high-capacity posts reduce the risk of personal injury even after a crash of high force. Thus our crash-friendly sign posts increase safety on the roads.

To develop the safest constructions for our roads, we have conducted crash tests on our aluminium pole products since the 1970s. The knowledge we have gained from these tests has led to a range of safe, secure, and crash-friendly aluminium solutions that reduce the risk of personal injuries after a collision.

  • Single-leg and multi-leg posts with signage
  • Bending moment up to 80 kNm
  • Installed on a baseplate, rigid foundation
  • Upon impact, the post breaks at ground level

  • Maintenance-free
  • Sustainable with 100% recyclability and Cradle to Cradle certified on the post profiles


Expertise in passive safety

Our expertise and years of experience in the execution of crash tests have led us to produce a whitepaper about passive safe light poles and support structures. We are happy to share our knowledge with you.
