Types Of Materials
Pressure- treated lumber is the strongest and least expensive choice for deck lumber. Pressure- treated lumber resists rot, decay, and insects and is an excellent building material for outdoor use. Treated lumber is created by forcing chemical preservatives into it under high pressure. The most common treatment uses , identified by the label "ACQ." The preservative usally gives the wood a green color, which fades with time. Or, you can stain pressure treated wood in a variety of colors.
Pressure treated lumber is rated by the amount of chemical retained by the wood. For decks, post and joists are selected with a retention level of .40, approved for direct ground contact. The decking boards are selected with a retention level of .25, approved for above ground use.
A deck made with cedar, one of the world's most beautiful woods, is apt to be one of the best looking decks in the neighborhood. Cedar decks, however are more expensive than the common pressure- treated deck. Cedar has a light brown apperance, with an attractive grain. Because it ages to a uniform silver- gray, cedar is often used where a weathered apperance is desired.
Cedar is one of the few woods with its own preservative oils, its freedom from pitch and resin makes it an excellent base for portective coatings. And cedar has other natural qualities that make it a good choice for decking. It is one of the most stable of softwoods, so cedar decks stay flat and straight and resist checking.
A deck built with cedar will have the structural part like the post, beams and joists built with pressure- treated lumber. The visible surfaces like the decking boards, railings, and borders will use the cedar wood.
