Our cattle guards are some of the strongest around. Cross-members are made from 3″x6″x1/4″ steel placed 30 inches or less depending on length. All our guards are 8 feet wide. Standalone models or made to set in concrete sills, the choice is yours. Available in sizes from 12-24 feet in length, we have the model right for your application. These guards are used in the oilfield and stand up to constant abuse. This product definitely lives up to our Built Strong to Last motto.
