Hello, Composite decking is great but you have to be very certain that you are getting high quality and original materials. When it comes to Trex, you need to know how to differentiate the fake products from the genuine ones in the market. First, make sure the board has a protective shell, if it doesn't then its not genuine Trex. secondly, look out for deep wood grains on the board and find out if it is made of 95% or more recycled materials.
