when I done my deck, weight would be a issue for me. Mine is constructed (frame) 2" thick wall aluimium angle & 1" thick wall aluimium tubing. The flooring is 3/4" top grade construction plywood topped with a rubber matting glued & trimmed in 1 1/2" alumium angle. I built the deck in halves the center were both halves meet have a neoprene gasket. I constructed the deck so if I have to work on wiring or add more electric I can just remove it by 6 machine screws and unplug it.
