Decking materials are the various substances used to create outdoor surfaces for patios, decks, and walkways. Common options include wood, composite, and PVC. Wood, such as cedar or redwood, offers a natural look but requires regular maintenance. Composite materials combine wood fibers and plastic, providing durability and low maintenance. PVC decking is made entirely from plastic, making it resistant to moisture and insects. Each material has its pros and cons, including cost, appearance, and longevity. Choosing the right decking material depends on factors like budget, climate, and desired aesthetics.
