I love decks. I used to love watching Paul Lafrance’s Decked Out TV show. That guy is a deck primary.
Because I’m so passionate about decks, I asked our graphics team to go all out on creating the ultimate “parts of a deck” anatomy diagram.
They delivered big time.
In fact, as you’ll see below, our graphic sets out the different parts for each aspect of building a deck. This is a super helpful diagram if you’re planning on building a deck or designing a deck.
