ABSTRACT:
A relatively thin side wall panel is formed of an array of sheet metal riveted sections formed from an aluminum coil to form inner and outer panel skins which are placed in a mold and used to form with the skins an injected thermoset plastic rigid foam core panel which is 48 foot by 9 foot and is about 0.9 inches thick. The panel is cut into three side panels for each container side. The roof is also formed similarly into a single panel of about 1.1 inches thick with an array of recesses which reinforce the roof panels and allow for thermal expression, the recesses containing the rivets of the adjoining skin sections. The panel is then cut to form three roof panels. A frame is formed of lower and upper extruded aluminum rails and lower steel rails at the front and rear, front and rear corner posts and two pairs of intermediate posts to which posts and rails the side panels are attached. The posts are interconnected to headers to which with the upper rails the roof panels are attached. A front wall containing fiberglass insulation between an outer metal skin and an inner plywood layer is secured to the front posts and a lower sill and upper header. The entire container weighs no more than a conventional all metal container without the heavier foam core panels and structurally resists bowing at the lower side rails.
