Decks are awesome outdoor spaces that add so much entertainment and enjoyment value to a home. But, what actually goes into a deck? What is the anatomy of a deck?

In this article, we will explain all of the components of your deck. 

The Parts Of A Deck

Whether you choose a composite or wood deck, there are many moving parts that go into building the structure. 

Essentially, your deck is a floor supported by different parts to make it structurally sound and secure to the ground.

The following terms are all critical or important features and components of your deck.
