Abstract
A refrigerator door has an outer member formed from a folded sheet of steel, with a front panel and a perpendicularly projecting flange forming a cavity. A reinforcing member of thin sheet steel has a front panel, smaller than the outer member front panel, with a perpendicularly projecting flange. The reinforcing member is positioned in the cavity. A body of insulation foamed-in-place in the cavity secures the reinforcing member within the cavity in spaced apart relationship with the outer member.
