| The most popular choice of deck material in the U.S is pressure-treated lumber, primarily because it's long-lasting and the most economical. Pressure-treated lumber is impregnated with salts, which prevent wood decay. This type of lumber is available in various grades; however, the use of pressure-treated lumber in and of itself is not enough to guarantee the quality of the deck. A well-built, quality deck will: -- have a good, solid foundation. Poured concrete footings with metal post saddles are the best. Small decks or those lower to the ground can be built on pier blocks. -- require flashing if fastened to the house in order to prevent water entry into the house; -- require water- and weather-resistant nails, fasteners, flashing, joint hangers and hardware. Hot-dipped galvanized material is a good choice unless you are near salt water, where stainless steel would be a better choice; -- not have contact with the soil, although pressure-treated lumber is capable of withstanding soil contact for 40-plus years; -- be water sealed to prevent cracking and splintering. This sealer should be re-applied every three years. About 80% of pressure-treated wood is southern yellow pine. Grain patterns are prominent, and its initial green color becomes a honey brown before fading to grey. It is available in almost every lumber outlet in various grades, and in common lumber dimensions, plus 5/4 decking profiles. Tags stapled on ends of lumber indicate the intended use, e.g., above ground or ground contact. Pressure-treated wood usually has a warranty against decay and termite damage, in most cases, for the lifetime of the original purchase. Pressure- treated lumber is used for many outdoor projects, and is generally a good choice. |
| Composite decking and railing products are made from a combination of reclaimed wood and plastic, giving the best qualities of both materials. The plastic acts as a shield from moisture and insect damage, so there is no rotting or splintering. The wood protects the plastic from UV damage, both contributing to the long life of the product. Because there is no need to spend hours staining or repairing, the enjoyment of a composite deck is truly timeless. Unlike wood surfaces, composite material: -- will not deteriorate due to harsh weather; -- is available in several finishes, smooth or wood grain; -- is available in several color options; -- is splinter-free; -- contains no toxic chemicals or preservatives; -- resists moisture, insects and sunlight, making composite decking the perfect choice for pools, hot tubs and spas; -- has excellent traction, even when wet. Composite material is made primarily with recycled plastic grocery bags, reclaimed pallet wrap and waste wood, making it environmentally friendly. While composite is low-maintenance, it is not maintenance-free. Period and regular cleaning is necessary to prevent mold growth and stains from adhering to the material. The plastic component of this material makes it susceptible to scratches, so care is needed in order not to damage the product in this way. Darker colors tend to radiate the sun's heat more than lighter colors. |

| CEDAR |
| Cedar is also available in many grades, the most popular being knotty and clear. When properly maintained, a cedar product may last as many as 40 years. Cedar contains natural oils which help prevent decay and insect attack. The wood has a dense cell structure, and shrinks and swells very little. It stays flat and resists checking. Cedar can be left untreated to weather naturally to a silvery gray color, or deck finish can be applied to preserve the rich colors. Periodic applications of sealer will help maintain this color. Cedar is one of the most colorful woods available for outdoor projects, and is usually the wood of choice for arbors, pergolas and gazebos. |
