Abstract: A knock down shipping container is provided with the walls of the container constructed of composite panels that are usable as exterior sheathing in building construction at the point of destination of the shipped goods. The container is assembled with a plurality of bolts as well as four upright corner posts formed by a pair of steel angle brackets, an inner bracket containing a plurality of threaded studs extending through the walls of the container and an outer bracket where tamper resistant nuts are threaded onto the studs connecting the inner and outer brackets together and thereby attaching the side walls together at the upright corners of the shipping container. The outer brackets include upper and lower standard corner fittings for use in stacking multiple containers and in securing the containers to a shipping vessel.
