A self-supporting structure constructed from an extremely strong, quality steel. The panels are easily used on all types of terrain including uneven ground—leaving a minimum gap between the panels. Also, the unique construction of Stroberg panels keep cows and calves from trying to go underneath. The panels are completely welded around the horizontal bars and joints. Extra time taken in welding workmanship insures added strength. The corral is transported on either a panel trailer or combination panel trailer/loading chute.
