CRASH TESTED H4A AND H4B
In the 1970's a concrete profile was developed to contain vehicles, this profile was referred to as New Jersey.
By adapting this profile and converting it to steel, with strategic reinforcement and a simple anchor arrangement the STEELGARD system was developed.
Modular in style and robust in nature the STEELGARD system is connected together using a specific and unique hinge assembly detail designed to provide a gateway for the distribution of energy amongst its members causing a failure of the anchors to create a heavy chain mechanism to occur.
By designing the system in this manner means heavier vehicles can be contained without increasing loads to the structure or concrete support.
The introduction of Steelgard changed the entire spectrum of vehicle restraint systems. Old fashioned procedures used to contain vehicles was replaced with new innovative ideas and mechanisms to dissipate energy designed to minimise occupant injuries and loadings to old structures. Steelgard remains the only very high containment restraint system crash tested and approved to both H4a and H4b containment criteria.
Suitable for bridge and verge applications. No intrusive cradle anchors denote savings in global bridge design.
