Hill & Smith’s signature creation, Zoneguard®, offers the road construction industry a revolutionary temporary steel barrier solution that provides superior protection. A cost-effective alternative to traditional concrete barrier, Zoneguard’s lightweight configuration allows 750 LF to be hauled on one truck and up to 1,500 LF to be installed in one hour. Zoneguard’s light weight does not affect its performance, as it meets both NCHRP 350 (TL-3 & TL-4) and MASH (TL-3) crash test standards. Finally, a safe temporary barrier solution that doesn’t weigh down your bottom-line.
