ROOF BOWS: The roof sheet will be supported by full width .125 inch thick x 2 x 2.25 inch architectural box tubing. The roof bows will be located on twelve inch centers. The roof bows will be MIG welded to the roof rail extrusions with no less than four and one-half inches of continuous weld per end. The roof sheet will be bonded to the roof bows with VHB (Very High Bond) adhesive tape. LATERAL ROOF SUPPORTS: If this agency requires ducted ceiling HVAC, additional structural support will be added as a result of the 2 inch ducted heat and A/C delivery system .2 x two inch three sided extruded channel with two sides being .125 inch thick and the bottom surface for fastener acceptance to be .160 inch will be full length of the body. ROOF CORNERS: The roof rail extrusions will be welded together along the roof bow mating walls at the corners. In addition, the outer surfaces of the roof rail extrusions will be 100% continuously TIG welded to cast aluminum corner castings. The castings will have internal mating flanges that extend horizontally inside the upper roof rail extrusion and vertically down the corner post extrusions. 6.4 Exception - The side sheet will be .125 thick, 5052-H32 aluminum. The side sheet compartment opening cut outs will be cut with CNC controlled, gantry mounted plasma or high speed routing equipment. The door opening will be cut to allow for the skin to be molded into the jamb opening to create a crevice free jamb with a smooth paint finish. The machine formed skin will return into the body at least 3/4" to meet the jamb extrusion. This method will encourage square openings to receive the door assemblies and maintain critical structural locations. The door jamb will have a full structure frame behind the jamb skin return. It will not rely strictly on the skin for the compartment jamb. Pre- determined ventilation louvers will be formed into the body sheet, where specified. Bodies that do not incorporate formed louvers have the potential for additional corrosion points and are not preferred by this agency. 6.5 Exception - Floor structures will be 6105-T6 aluminum, 2.000 by 2.500 inch proprietary hollow section architectural box tubing aluminum. This proprietary shape tubing allows for half-inch plate to be recess to which floor mounted items can be securely connected. Each member will have a defined bevel built into the extrusion die to allow for full weld penetration on the edge of the extrusions. FLOOR HORIZONTAL GUSSET PLATES: The floor member to side wall fully welded horizontal gusset system will be made of 5052-H32 aluminum plate, four (4) by four (4) inch triangles. A minimum of 12 gussets will be located horizontally connecting cross members to longitudinal main center members at each main cross member site. FULL WIDTH CROSS MEMBERS: The module floor will provide core support for the side assemblies and will incorporate a minimum of four(4) full body width floor members. The full width floor members will connect to and support the side wall assemblies. Each member will be made of 6105-T6 aluminum. The front floor tube is to be a minimum of 3.000 x 2.000 x .250 inch thick 6105-T6 aluminum tube which is fully MIG welded into the front corner post at each side of the vehicle. On top of the tube is to be a minimum .188 thick 5052 aluminum front sill running full width of the body. One of the members located just forward and/or rear of the rear wheel housing will be 2.000 by 2.500 inch proprietary hollow section architectural box tubing. The last floor cross-member will be a 2.375 x 3.188 6105-T6 aluminum proprietary shape proof tube on the rear wall which is fully MIG welded into the rear corner posts at each side of the vehicle. This tube is butted up and welded to a 2.000 x 1.000 x .125 inch thick
