Since its debut in 2008, Hill & Smith Inc.’s Zoneguard has been the most widely used temporary steel barrier system on America’s roads and highways. Tested to NCHRP 350 and MASH crash test standards, Zoneguard offers maximum safety. The ability to haul 750 LF of barrier on one truckload significantly reduces freight costs and accelerates installation and relocation, making Zoneguard a cost-effective alternative to traditional concrete barrier.
