Asking about whether or not I can remove the diagonal 2x6 boards nailed diagonally under my deck joists if I will be putting up 2x4s across the underside of the joists from left to right every 3 ft (I'm adding them to serve as the mounting for a corrugated PVC under-deck ceiling). I figured the bracing, while not diagonal, should still provide adequate bracing as a strong grid and make putting the left to right 2x4's easier without those 4x6's in the way. Would that work? Thanks in advance.
Would be best to see a photo first to fully understand what you are describing. It sounds as though someone nailed a 2x6 on the underside of your deck to square it up then forgot to remove it. I dont see any reason why you wouldn't be able to remove it safely. But again this is without seeing it and any safety issues will be based on your discretion only.
That diagonal bracing is installed to stop the deck from racking out of square. It is highly advisable to shim your ceiling framing over the bracing. Lateral framing does not work the same as diagonal. Its more work, but its the proper way to do it
