In engineering, a deck is a level surface fit for supporting weight, like a bottom of a room, yet normally developed outside, usually lifted starting from the ground, and generally associated with a building. Wood or timber “decking” can be utilized used in many cases: as a component of landscape around the house, and as  an alternative to the stone based floor , for example patios, yards. Decks are produced using treated wood, composite timber, composite material, and Aluminum. Wood might be Western red cedar, teak, mahogany, ipê and different hardwoods. Reused boards might be high-thickness polyethylene (HDPE), polystyrene (PS) and PET plastic and blended plastics and wood fiber (frequently called “composite” timber). Fake decking items are regularly called “wood-plastic composites”.
