Install Bracing Between Deck Posts. Install all of the beams the same way. Once they are all in place, screw diagonal bracing between the posts. The bracing is important for structural integrity and helps prevent racking — a side-to-side or front-to-back shifting of the structure. The bracing for this deck is 2 x 4 treated lumber.
Ledger Board: Whenever the deck is attached to the house, a ledger board is used. In general, ledger boards are the same size as the floor joists. After selecting a straight piece of lumber for the ledger board, the ledger is bolted to the house's framing. Given the potential for injury should the deck break apart from the house,
How to build & install a built-up structural beam for decks, porches, & simliar structures. This article describes how to build a beam used to support a deck or porch floor or similar structure. We describe building the beam out of 2x lumber in four easy-to-follow steps. The article concludes with a description of different methods
A new series, brought to you by Cottage Life, Jason Lake shows you common mistakes, and easy fixes for building a deck. By having the top of the post flush with the top edge of the beam the post end will end up above the beam edge (after the wood shrinks) and a bulge or crack will appear in the
cost prohibitive for larger projects. The four main components of the deck are the posts, beams, joists, and decking. Posts consist of 4 x 4 lumber. Beams typically measure 4 x. 6 and are usually made by nailing two 2 x 6 pieces back to back. Joists are normally 2 x 6 lumber. Face decking boards are either 2 x 2, 2 x. 4, or 2 x
When securing 2 or more dimensional wood boards together to form a beam you will need to use the proper number and size nails to create a solid member. A 2x10 Beam should use a minimum of (4) - 3” nails fastened in a vertical pattern from both sides of the beam every 16” on center. Be on the safe side when in doubt

Sizing deck beams got a lot easier when the 2015 IRC came out. Deck builders can now refer to Section R507.6 Deck Beams and Table R507.6 Deck Beam Span Lengths to sort out the size of 2-ply and 3-ply built-up beams made from 2×6 through 2×12 lumber. Sign up for eletters today and get the latest

The span of a beam is dependent on a few variables. The species of lumber, size of lumber and the load it carries. Fewer posts on upper level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Beam span maximums are based on a maximum anticipated
Using an engineered beam will reduce the number of posts blocking windows under a deck or may provide a clear span for a deck over a driveway. These beams are designed much stronger and more stable than standard dimensional lumber beams. It is possible to achieve spans up to 20 feet. Engineered beams must be
