Therefore, I am toying with making a screened bottom board out of Trex. Trex is an extremely durable product that is made from wood and plastic fibers. It is a very popular material to make decks out of because it holds up so well outdoors, but I have not seen any beehive components made from Trex. Trex is pretty expensive, but I was able to salvage a few short pieces from a dumpster at a construction site last summer. I already used some of it to make a pretty cool Trex birdhouse. Below is a pic of a rough prototype. I can't wait to finalize assembly and throw it under one of my hives.
