As of 2015, some different types of decking products include pressure-treated lumber, redwood, western red cedar, plastic decking and composite decking. Composite decking, which is primarily composed of recycled plastics and wood fibers, is produced by a number of different companies, such as Veranda, Trex, CorrectDeck and TimberTech.
Composite decking usually comes in a variety of different colors, and is extremely stain-resistant and weather-resistant, meaning it won't warp, split, splinter or rot.
Plastic decking is generally constructed from 100 percent plastic, usually polyethylene or polyvinyl chloride. Like composite decking, it is also available in a wide range of colors and is resistant to staining and weathering. Some of the companies that produce plastic decking include Leisure Decking, ForeverDeck and Azek Deck.
Pressure-treated lumber is the most commonly used decking material, with approximately 75 percent of all new decks being covered with pressure-treated decking. Usually made from southern yellow pine that has been chemically treated to resist fungus, rotting and wood boring bugs, pressure-treated lumber is usually the most affordable type of decking material.
Redwood and western red cedar are both popular types of decking, and contain a variety of tannins and oils that make them naturally resistant to decay, fungus and insects. Both types of lumber are more resistant to cracking, splitting or warping than pressure-treated lumber, although they are usually three to five times more expensive as well.
