Heavy duty cattle guard ratings for the H-15, H-20, U-54 and U-80 rated cattle guards are set by the AASHTO for use by state and federal agencies in public roadway projects. These guards are available in lengths of 8 feet, 10 feet, 12 feet and 14 feet and can be installed end-to-end to meet your road width requirements. The finished top of these guards are flat and provide a smoother transition for crossing vehicles than round top cattle guards.
