Last summer, my son and I built a 16x20 ft deck using Trex. It was great to work with. I still have some trim board to put up, but will need to take the trailer back to the lumberyard to pick up 3 more sticks of trex.
We wanted benches on one side and a nice rail on the other side. Since trex has little strength, I fabbed some bench brackets and rail brackets out of 2x3 angle iron and placed 3/16 x 4 flat iron under the trex for the rails and benches. After welding all the iron up, took it in to be powdercoated.
Pics aren't that good, but you get the idea. We love the deck!
