The Andersen will do well as long as you only subject it to vertical loads and light lateral loads. Any lateral load will reduce the load on 1, 2 or 3 of the legs and load the remaining legs in a high compressive load. A cylindrical column will do well as long as the load is on its centerline axis. With one end anchored and a load off the centerline, the column will be subject to bending or buckling. If the thickness cannot tolerate the off-center load, failure will occur.
