A tool box having a reinforced door that withstands prying and resists flexing during use. The door includes a reinforced region including a first flange, a second flange and a third flange extending from the first edge of the door. At least one additional flap extends from an edge of the door adjacent to the reinforced region and is welded to the reinforced region to provide additional strength. In another embodiment, a second and a third additional flap is included on the door, and each additional flap may be welded to an adjacent flap or welded to the reinforced region. Multiple reinforced regions, each including at least one flange, may also extend from the door body to provide increased strength.
