  • Zoneguard® Steel Barrier
    The Zoneguard® steel barrier system has been extensively crash tested to the newest set of standards for roadside safety devices, MASH and has received eligibility from the FHWA....

  • Since its introduction to the highway safety industry in 2008, the Zoneguard® steel barrier system has become the most widely used temporary steel barrier in the country, and its many safety and money-saving benefits have been realized by DOT’s and contractors throughout the US.

    Designed to protect highway travelers, as well as road and construction crews, Zoneguard® offers the maximum safety requirements, as it meets NCHRP 350 and MASH crash test standards.

    Temporary concrete barrier systems are costly, heavy to transport and handle, time-consuming and do not provide the energy-absorbing capabilities of Zoneguard®.

    Today’s contractors, engineers and DOT’s have a responsibility to provide the upmost safety to the driving public, while meeting tight budgets and timelines.
