Consumers are turning to wood-alternative post options that require less maintenance. From a durability and strength standpoint, a steel or composite post are the best options. The Trex composite post is superior because it won't rust and it adds the virtue of a natural, sturdier appearance that is more compatible with the look of wood. The core of the post is hollow (which makes it easy to use as a sleeve, if needed), but the thick wall does not require reinforcement for most applications.
