Span Charts and Options

Framing

Span Charts

Calculations are based on 40 psf (pounds per square foot) live load with a 10 psf dead load. These charts provide common – but not complete – deck framing information. Please check with the local building department for the requirements that apply to your project.

LVL framing lumber is super strong, straight, and works like wood. Treated LVL from Pacific Wood Tech uses proprietary Tru-Core ® technology, including treatment chemistry in both the glue and wood treatment, producing boards that are consistent, dry after treatment, not corrosive to fasteners, carrying 25-year transferable warranty.

Traditional treated lumber is more expensive today than it was only months ago. Treated LVL today costs about 60% more than treated lumber. Treated LVL is stronger, however, and may replace larger profile treated lumber. So for a typical deck, upgrading to treated LVL costs about $2-3 more per square foot. But also consider that treated LVL eliminates some traditional frustrations of working with wood, so it’s faster to build with and flatter when it’s done.

Our treated framing lumber is #2-and-better Southern yellow pine (SYP), with “Treater Series” computer-aided log-grading technology developed by Weyerhaeuser. Treater Series is noticeably straighter than other treated lumber. Additionally, our treated lumber is also kiln-dried after treatment (KDAT), making it lighter and easier to work with. Open units of lumber are stored indoors.

Metal Framing

Metal framing systems have been growing in popularity. While we do not stock metal framing, you can ask your salesperson about available systems made by Trex or Fortress.
