An open top container having at least one side wall constructed of vertically disposed panels having horizontally extending corrugations or ribs lending beam and column strength to the side wall panels. The panels of that side wall can have an interconnecting slip joint permitting limited horizontal movement between the panels. One or more of the side posts of at least that side wall can have inner and outer sleeved sections permitting vertical movement of the bottom end relative to the top end while restricting horizontal movement and forces. The side post vertical movement permits the transference of portions of the vertical, load imposed forces from the top rail to the corrugated ribs of the side wall panels. The composite beam consisting of the top rail, bottom rail, corrugated panels and side post can be prestressed for additional advantages. Also, both walls of a rectangular container for maximum advantage should include the horizontal corrugations and the sleeved side post.
