Re: trex composite
Trex is a very good product, been around for many years and holds up in any weather. The only drawback I see, is that Trex is fairly heavy compared to wood, and you would need to support it with brackets or wood framing to hold it up. It really depends on the design of the shelves, and what you are going to put on them. Trex will also scratch, and it will stain if you pour certain things on it. Let me know more of what you intend on putting on these shelves, and I could probably offer more suggestions. Griggsmars
