Alden-
If the edges on your plywood have not delamiated after 3 year outdoors, count yourself very lucky. Remember that plywood is not always 100% solid and there may be voids in the sheet, along with areas where the composition isn't perfectly uniform. When you rip it down to strips for the grating, you're going to have a hundred times more 'edges' than you do now. If they start to delaminate, that's going to be a huge waste of both time and money.
Please...consider that all the "teak grating" on the market is SOLID NOT PLY and maybe there's a reason for that. Solid teak grating, and grating kits, or small strips of framed teak (or ipe, which is extremely similar but much cheaper) aren't that expensive. You are betting that your "3 years" plywood will last and wear like the "40 years" grating. I don't think you could get odds on that happening, even in Vegas. Not even ten years, and 50-50 says it will be a mess before five years are up. Especially since grating gets stepped on all the time, and that will cause serious flexing (compared to the sheets that just sit) which in turn will promote delamination.
Are you a gambling man?[g]
