A pressure-treated 2×10 is a common size of wood used for framing. The lumber is treated to prevent decay and rot, so it can last many years under the harshest conditions. This process uses considerable energy, but does reduce the need for preservatives in new construction materials like cement or plastic which would require more energy over their lifetimes.
The “pressure treated lumber span chart” is a table that shows the maximum spans for pressure treated lumber. The table also includes the allowable load and weight of each type of wood.
In general, 16-inch-on-center joists may reach 1.5 times their depth in inches in feet. A 2×8 may be up to 12 feet long, a 2×10 can be up to 15 feet long, and a 2×12 can be up to 18 feet long. The joists become bigger as the deck gets bigger.
How long can a 2×10 span without support, given this?
A double ply beam may span in feet a value equal to its depth in inches when supporting joists that span 12 feet with no overhang beyond the beam. A double 2×12 beam may span 12 feet, while a (2) 2×10 beam can span 10 feet, and so on.
As a result, the issue becomes: how broad can a 2×10 span be? No 2x8s fulfill the span and spacing criteria, as shown in the chart, but a 2×10 with an E of 1,300,000 psi and a Fb of 1093 psi can span 15 feet 3 inches, which is more than adequate. Because it can span 15 feet and 10 inches, a 2×12 with an E of 800,000 psi and a Fb of 790 psi also works.
