  • Zoneguard® Steel Barrier System
    Zoneguard® offers the road construction industry a revolutionary temporary barrier solution that provides superior protection (MASH tested)....

  • 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.

    Zoneguard® provides a cost-effective and efficient barrier solution and is available nationwide for rent or purchase.
