Some deck builders have noticed premature rot in treated decking and framing. Are new preservatives and lower retention levels (compared with old 0.40 CCA-treated lumber) to blame, or is the problem the use of above-ground-rated lumber when ground-contact-rated material is required?

Pressure-treated lumber is rated according to the pounds of preservative retained per cubic foot of wood; the higher the number, the better the protection against fungi and insect attack. Select decking boards with the preservative concentration suitable for their use.
On Jan. 1, 2004, the EPA banned chromated copper arsenate from use in pressure-treated wood for residential projects. This article looks at the new pressure-treated wood, which is arguably safer to people and the planet, but is more corrosive to fasteners.
Apart from structural wood preservation measures, there are a number of different preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, wood structures or engineered wood.
Because ACQ and CA contain more copper (an expensive commodity) than does CCA, one way for lumber treaters to hold down costs is to treat lumber only to a level appropriate for its likely use. So, post-size — 4x4, 4x6, and 6x6 — lumber is generally treated for ground contact, but most lumber dimensions used for joists, beams, and decking ...
Chromated copper arsenate (CCA) has been used extensively in this country as a wood preservative. CCA is composed of: copper, which acts as a fungicide; arsenate, a form of arsenic, which is an insecticide; and chromium, which binds the ingredients to the wood.
Copper azole is registered for treatment of millwork, shingles and shakes, siding, plywood, structural lumber, fence posts, building and utility poles, land and freshwater piling, composites, and other wood products that are used in above-ground, ground contact and fresh water as well as in salt water splash (marine) decking applications.
This lumber is pressure treated in order to protect it from termites and rot. Ideal for a variety of applications including decks docks ramps and other outdoor projects where lumber is exposed to the elements.
These include ACQ-C (Alkaline Copper Quat Type C), ACQ-D Carbonate (Alkaline Copper Quat Type D, Copper Azole Types B and C, as well as Zinc Borate preservatives. Top Choice Treated wood is safe to use for play-sets and other child-focused structures, around vegetables, people and pets.
ACQ-treated timber can be painted, but this is not necessary. In the US and other countries, ACQ is registered for use on: lumber, timbers, landscape ties, fence posts, building and utility poles, land, freshwater and marine pilings , sea walls, decking, wood shingles, and other wood structures.

So, post-size — 4x4, 4x6, and 6x6 — lumber is generally treated for ground contact, but most lumber dimensions used for joists, beams, and decking are not. The tag on the end of each board notes the level of preservative retention and states whether that board is allowed to contact the ground (see sidebar).
Today, pressure-treated lumber is treated with a range of inorganic chemicals rather than arsenate. Other common chemicals used are Alkaline Copper Quaternary (ACQ), Copper Azole (CA), Sodium ...
