Before you get to excited about Trex.... I don't think it will work for a door....
"Can Trex lumber be used for deck posts or joists?
No. While Trex lumber is tough and durable, it does not have the same stiffness as wood. Therefore, it is not intended for use as a load bearing post, joist or any other primary load-bearing member."
The prime word here is "same stiffness as wood".
