Steel Safety Barrier Systems


Holgate provide an extensive range of steel safety barrier systems tested to EN1317 and with CE marking. The most popular systems include our VETEX range of N2 to H2 systems from TATA. We also have a very sucessful association with Fracasso who are one of Europes leading manufacturers and developers of vehicle containment systems and provide a range of high containment systems to meet all senarios. Holgate also promote the Blue Systems Wire Rope Safe Fence systems and have an extensive range of In house products and numerous other systems from across Europe.

The following table outlines the various criteria for crash barrier systems under EN1317 dynamic testing:
