Joist Layout for Stronger Decks Professional Deck Builder 20 Mar 2013 Another option for determining spans is to use the span charts in the American wood Council's DCA6-09, Prescriptive Residential wood deck Construction Guide (free at awc.org/publications). Keep in mind that joist spacing may be dictated by the type of decking boards to be installed and how they are to be laid out. While most wood and synthetic decking installed perpendicular to the joists can span 24 inches, some kinds require joists to be as close as 12 inches
Don't Build Decks That Rot Professional Deck Builder Lumber 1 Mar 2007 To extend deck life, eliminate pockets that catch water and debris. Poor deck design and even some common building practices create what I call “collection zones” — places organic matter and moisture can accumulate — usually where two pieces of material meet. And not only does this organic Wrapping a 12-foot-by-16-foot deck with fascia (left) creates 40 linear feet of potential collection zones, where rot-encouraging debris gathers at the rim joist.

Decks. Pressure Treated Wood Species & Sizes of Pressure Treated wood. Treated wood is generally available as dimensional stock in 2x4's, 2x6's, 4x4'x, and 2x2's for rail components. 5/4x6's and 2x6's for decking. 2x8's, 2x10's, 2x12's for joists, stair stringers, and beams. 6x6's for support posts. Also plywood. The predominant species of treated wood is a regionally available softwood. Most common are: Southern Yellow Pine - Southern Pine is the most common deck framing material in eastern United States.
How to Buy Deck Lumber - The Family Handyman 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. The three common ratings: Above-ground use (.25, sometimes .15). Typically used for decking, fence and railing material. Ground-contact use (.40). Typically used for posts, beams, joists and, again, decking. Below-grade
Decks. Different Types of Joist Hangers joist hangers can be used anywhere you need to strengthen a load bearing connection. joist hangers use face mount attachments to fasten joists to ledger boards and beams. You can buy joist hangers for different size lumber. Single, double, triple, right and left orientation hangers are available for various applications. Many builders underestimate the extreme importance of selecting and properly installing the appropriate joist hangers. Make sure to fill all of the required nail holes

Decks. Deck Joist Cantilever Rules and Limits 30 May 2017 The distance your joists can safely cantilever or overhang a drop beam is determined by the size of the joists, the wood type and grade of the lumber and the spacing between joists. Many building departments limit joist cantilevers to 24" maximums. You must use at least 5 framing nails to attach the rim joist to the ends of your joists. The American wood Council states that cantilevers are limited to 1/4 the span of the joists.

construction guides for exposed wood decks - National Agricultural Lumber Species anol Characteristics. Many lumber species will provide good ser- vice in a wood deck. However, som_e are more adequate for the purpose than others. To select lumber wisely, one must first single out the key requirements of the job. Then it is relatively- easy to check the properties of the different wood to see which ones meet these require- ments. for example, beams or joists require wood species that are high in bending strength or stiffness; wide boards in railings
