With a light �nudge� impact, the ZEE Park Post deforms�elastically within tightly controlled limits. When the force is�removed the ZEE Park Post springs back to its original position.�With a more severe impact, the ZEE Park Post yields in a�consistent and predictable manner, absorbing much of�the vehicle�s energy - without overloading the anchor or�damaging the structure.�The innovative ZEE Park Post�permanent deflection is directly proportional to the energy�of the impacting vehicle. Individual ZEE Park Posts will only�need replacement after a substantial impact, and have been�proven to effectively absorb over twice the force proscribed�by standard AS/NZS 1170.1 for light traffic areas.
