look for PVC covered composite
Composite decking materials have been around a while now and their popularity has plateaued. Composite materials are made from various post-consumer products like plastics and woods. They will last longer than wood with less maintenance but they have some cons of their own.
Composite decking materials are known to allow mold growth. This will depend on your climate and can easily be washed off but it is something to keep in mind. Composite decks will, also, expand and contract much more, with the temperature changes, than wood. This is rarely a problem for homeowners, however. The color can fade quickly with composite boards and some styles are quite slick when they get wet. PVC decking materials are relatively new to the market but have already left their mark.
PVC is virtually, maintenance free and can be cleaned with a garden hose. PVC decking materials now come in several different colors, including earth tones so you don't have to settle for white vinyl. PVC will be more expensive than other materials to build with but it will last much longer and require much less maintenance. To reduce the cost a little, you can look for PVC covered composite. Some of these simply, have PVC covering one side to protect it from the weather.
