Deck girders & beams guide: This article reviews the proper construction and connection of beams or girders used to support a deck or porch.

Our page top photo shows an unsafe (incomplete) deck girder construction with only minimal connections between the girder and the post top.

When you find a deck built like this one, it makes sense to check every point where a connection should have been made.
This article series discuss best porch & deck construction practices, including choice of framing materials, decking or flooring choices & installation, how to select and use deck and porch structural and flooring fasteners, actual deck & porch framing construction details & connections, deck joist & beam span tables, how to build leak-proof rooftop decks, construction of covered & screened porches, deck & porch railing construction & materials, choices of finishes and stains for decks & porches, and past & current deck lumber preservative treatments with related health & environmental concerns. This article series includes excerpts or adaptations from Best Practices Guide to Residential Construction, by Steven Bliss, courtesy of Wiley & Sons. Also see our review of that book.
For the strongest connection of beam to post, place the support beam directly on top of the posts, rather than bolting them to the side, so the full load is transferred to the posts.
To keep the post in place and to prevent any twisting or shifting, the connection should be reinforced with steel strapping, a steel connector, or a treated plywood cleat (Figure 4-13).
In general, notching a 4x4 post will leave too little wood for an adequate connection. A double 2x beam can rest on a notched 6x6 post, as shown.
For the strongest connection of joists to the support beam, the joists should sit on top of the beam. For a more streamlined appearance, however, joist hangers are acceptable.
Make sure the hangers and nails are approved by the manufacturer for use with the new types of pressuretreated wood (ACQ or ACZA) and fill all the holes in the hangers with properly sized nails.
In general, nail into the joists with 1 1/2-inch joist-hanger nails and nail into the beam with 10d to 16d common nails, as specified by the hanger manufacturer. Sizes for joists and beams are shown in Table 4-7 and Table 4-8 below.
