Trex - Slightly more expensive than ChoiceDek, this man-made material is similar to a particle board wrapped in plastic. Trex advertises that it requires no maintenance beyond regular cleaning. Trex comes in two colors: "natural" (which fades to light gray) and "Winchester Gray" (a slightly darker gray). You cannot paint or stain Trex to achieve a different color.
Forever Deck - This is the most expensive of the three man-made materials mentioned. This is a recycled plastic that works like a plastic version of lumber. That means that it can be sawed, cut or routed just like wood. Forever Deck material comes in a variety of colors that run through the material, so if you do cut it, you won't see a seam or a different color on the interior of the plastic. You cannot stain or paint Forever Deck material to achieve a color different from the color options provided by the manufacturer.
