Abstract: A panel assembly for providing underdeck water drainage and for other applications such as wall panels and skirting for exposed areas under building. The panel assembly, for an underdeck water drainage system, includes a plurality of joist brackets that are mounted transversely to and under the joists of a deck, a plurality of drainage panels, a plurality of drainage panel brackets, and a plurality of joist bracket spacers. The drainage panels may be slidingly engaged or snapped into separate panel brackets or into panel bracket portions of adjacent drainage panels. When properly installed, the underdeck drainage system will protect an area of interest, such as a patio or storage area under a deck, from rain water and keep the area dry. Another application of the present invention is to provide a shield, skirt, or cover for an exposed area under a deck, a home, a mobile home, a wall, or other place of interest.

Abstract: An apparatus and method for creating expanded and non-expanded regions on a sheet of sheet metal. The apparatus includes a programmable controller, a sheet metal feeder for incrementally advancing the sheet metal, and a cutter/expander for generating rows of expanded metal apertures. The controller selectively controls both the amount of incremental advance provided to the sheet metal by the feeder and the timing and location of the cutting and expanding provided by the cutter/expander; the combination of which creates such regions.
