Lumber utilized in deck construction typically falls into one of the adhering to classifications:
Pressure-Treated Deck Lumber
Pressure-treated lumber (PT), generally want or fir is infused with chemicals that make it extremely rot-resistant. The chemicals additionally give the wood an environment-friendly or brown cast, which you can conceal with stain or paint or allow the climate to a dark grey. Pressure-treated lumber is the least costly, yet you’ll have to pick thoroughly to obtain a supply that is straight and without loosened knots.
Naturally Immune Deck Lumber
Naturally immune species, such as cedar, redwood, and cypress, are resistant to rot as well as pests, a quality most characteristic of the heartwood, the thick centermost core of the tree. You can seal or discolor these woods to maintain their all-natural elegance or let them weather to various tones of gray.

Framing: Unless your layout requires the same timber throughout the entire framework (as well as your budget plan can endure the sticker label shock of all-natural heartwoods), pressure-treated lumber is a great choice for framing. Usage lumber rated for ground call for posts and also mounting participants within 6 inches of the soil. Try to find a quality stamp that claims “ground get in touch with” or indicates a therapy deepness of 0.40 or better. Some pressure-treated species are less porous than others, so they’re incised prior to being dealt with.
These cuts still show after therapy, so location this lumber where it will be much less visible. Timber that has been kiln-dried after treatment (KDAT) is of the highest quality.
Articles: 4x4s or 6x6s are conventional for deck articles. Cut cleats and also stiffeners from 2x4s; for joists as well as beams, utilize 2x6s, 2x8s, 2x10s, or 2x12s. Choose PT lumber with care. Some boards will be smaller than basic nominal sizes. An unattended 2×10 will certainly gauge 9-1/4 inches, a PT 2×10 may just be 9-1/8 inches wide.
Decking and barriers: These are the most visible parts of your deck, so you’ll want to use the best lumber you can pay for. Redwood, cedar, and cypress, as well as the unique varieties, are good choices, however considering that many outdoor decking boards from residential woods are sapwood as well as not rot-resistant, you should treat them.
For the deck surface, you can make use of 2x4s, 2x6s, or 5/4x6s. The 5/4 outdoor decking (pronounced “five-quarter”), readily available in cedar and pressure-treated fir, is 1 inch thick and also 5-1/2 inches vast with rounded edges that create a splinter-free surface. Cedar 1x lumber generally has one harsh side and also one smooth side. Put the rough side down.
