Absolutely CRUSHED this huge framing day with ProWood TrueFrame Joist!!

What happens here

With the main support beams established, the floor joists for the first major section of the deck are installed. These joists are typically smaller dimension lumber (e.g., 2x8 or 2x10) and are spaced at regular intervals (commonly 12 or 16 inches on center), running perpendicular to the main beams. Workers are shown rapidly cutting joists to length, positioning them on top of or alongside the beams, and then fastening them securely using an impact driver or nail gun. This process forms the grid that will support the decking surface.

Goal: Create the subfloor framework for the initial deck area

Tools and materials

  • Chalk Line — Marking consistent spacing for joists along beams and ledger boards
  • Circular Saw — Precisely cutting joists to length
  • Deck Joists — Creating the subfloor surface upon which decking will be laid (e.g., 2x8, 2x10 pressure-treated lumber)
  • Deck Screws — Fastening joists to beams and ledger boards
  • Impact Driver — Driving deck screws to fasten joists securely
  • Joist Hangers
  • Measuring Tape — Accurate measurement of joist lengths and spacing
