Safety barriers and parapets

There are sev­er­al types of safe­ty bar­ri­ers. The most com­mon types are met­al bar­ri­ers with beams, tubes or wires as lon­gi­tu­di­nal mem­bers or are made from con­crete.

Safe­ty bar­ri­ers can be clas­si­fied depend­ing on area of appli­ca­tion like safe­ty bar­ri­ers and vehi­cle para­pets. Com­mon for all safe­ty bar­ri­ers are that they should be test­ed for a con­tain­ment lev­el and CE-marked. The per­for­mances of a safe­ty bar­ri­er are described by:

  • Con­tain­ment lev­el
  • Dynam­ic deflec­tion, e.g. how much the bar­ri­er is deformed (or dis­placed) momen­tar­i­ly
  • Work­ing width
  • Vehi­cle intru­sion
  • Impact sever­i­ty lev­el
  • Class of resis­tance to snow removal
