Our standard rear bumper is made of 4"X2" rectangle tube with a 3/16" thick wall.  Rear bumpers are double taper cut on ends.  Shackle points are 3" tall X 3/4" thick high-grade steel.  Mounting depends on application, typically with at least 6 mounting points, some applications require a frame tie in bracket and additional holes in the rear crossmember.
