I saw my first cattle guards out in Arizona two years ago. I had no clue as to what these metal grates were until I saw the cattle standing near one. They had no want to cross it. These didn't have the rolling pipes in them. They were made from flat bar stock with the thin edge standing up. The spaces were 3-4" apart and about a foot wide lenghtwise in size. I didn't know why the cows couldn't walk right across this. I think it could be because they can see down through the openings.
