Is Trex Durable? What is it made out of?

Trex is built from a composite material that consists of 95% recycled film plastic wrapped in a hard shell. This design allows it to hold up through long term exposure to all the elements it would in any environment it is set in. With minimal upkeep required Trex is one of the most durable composite options on the market. Trex will last between 25-30 years and it comes with a 25 year fade and stain warranty.
