I decided to build my garden RR elevated and would like to know what products are the most flexible to bend around a 8-9’ circle. I did watch a YouTube video on bending Trex decking which goes into heating the decking and bending on its flat side, I would like to cut the decking in strips, say 2-3" wide and install it on the sides, up and down not flat. What I’m thinking is the decking cut that way will probably bent much easier, anyone done this. Texas sun and weather is over 100 degrees these days so laying this material should heat it up to 140 degrees laying on concrete. Do note in the Trex video they heat the decking to around 225 degrees for bending, but they are bending it to lay the decking flat. I guess there is also PVC boards that could be used, or are there other material that are used that will flex, Hardiebacker strips would be great, but not sure of its flexibility. I’ve watched several YouTube videos on above ground RR, but most never tell what product they used for their flexible curves, I would rather not use wood here, but a man made product that will flex and withstand the elements is what I would like to use.
