Pressure treated wood has been used for many years for telephone poles, docks, bridges and even as building foundations in the place of masonry. Decks will almost always be constructed using pressure treated wood for the framing materials and, in most of the country, is the predominant material for deck platfomrs and railing. Treated wood meets a variety of essential requirements for this purpose. It is strong, resistant to decay and termite infestation, highly durable, easy to work with, has widespread availability and is inexpensive.

Caution: Never burn treated lumber.  Always use a dust mast when cutting lumber. Make sure to wash your hands before eating after handling building materials.
