What happens here

Joists, typically 2x8 or 2x10 treated lumber, are spaced evenly across the main beams. They are secured using joist hangers, nails, or structural screws to create a rigid and flat surface. Precise spacing is crucial for proper decking installation and load distribution.

Goal: Deck joists are installed perpendicular to the main beams, forming the subframe upon which the decking boards will be laid. This creates a sturdy and level surface for the deck.
