Install Primary Joists

What happens here

With the ledger board and main beams in place, the next step is to install the deck joists. These are typically smaller dimensional lumber pieces (e.g., 2x8, 2x10, or 2x12 treated lumber) that run perpendicular to the ledger board and main beams. The joists are cut to the appropriate length to span between these supports. Joist hangers are metal connectors used to securely attach the joists to both the ledger board and the main beams. These hangers are fastened using specific hanger nails or screws. Proper spacing, typically 12 or 16 inches on center, is crucial for the stability and load-bearing capacity of the deck. Workers in the video are clearly seen measuring, placing, and fastening joists across the established frame.

Goal: Create the horizontal framework that will support the deck boards.
