Step 1 Construct the Deck Beam
The first step to building a deck frame is to construct the beam that will support the floor joists that will be attached to the ledger. The beam will consist of two 2” x 10” boards screwed together. Our deck beam will be cantilevered, which means the joists will extend past the beam. This results in a more visually pleasing look. To support the beam, use a metal post saddle to attach the beams to 4” x 4” posts.
