Default now that these composite lumber materials are old

have never used any of the composite materials for anything

i came across some discards and i noticed that they are flaking
not sure how old they are but natural woods last a long time and i have
a good understanding of failure modes in wood but not at all with this
composite material

also this plastic is so much heavier than equivalent wood that i would
say that a structure like a deck would need a very much more sturdy
pilings and cross members to support the increased weight


but i wonder more how these composites are doing that are out there
anyone have any decks or etc made of these materials


how old and how are they holding up










I have a small composite/plastic deck and it is holding up perfectly after
15+ years with the only maintenance being annual pressure washing to get
rid of the inevitable mildew buildup in a humid region. The deck is on the
north(ish) side of the house and gets direct sunlight only during late
afternoons in the late spring, summer, and early autumn so that might
contribute to its lack of deterioration.
