ABSTRACT:
A door (10) includes a front panel (18) and a back panel (24). The front panel and back panel are secured together by connecting members (42 and 44) which are connected by weld (82). Panels (18 and 24) include sides (32 and 38) that are dimensioned to maintain cover strip (90) therebetween. Cover strip (90) conceals the welds (82) that result in a smooth finish for the side of door (10). Panels (18 and 24) are also joined by connecting members (92, 104, 120 and 122) and welds (116 and 144). A channel member (118) is maintained between connecting members (92 and 104) to conceal weld (116). Support members (154 and 160) are also provided to panels (18 and 24).
