<p>The present invention relates to a weight reduced door frame for a cargo truck. More specifically, the weight reduced door frame for a cargo truck can prevent water from being infiltrated into the inner portion of the floor of the cargo truck by forming a bonding groove in a lower frame to be connected with a drain-pan angle which is formed on the floor of the cargo truck; reduce the weight relatively by forming a pillar, the lower frame, and an upper frame differently; and reduce the working hours by forming a jamming protrusion on the lower frame to be fixated immediately to the cargo truck frame without additional equipment in assembly.</p> |
