Let's find out [Book Free Deck Consultation](https://3brothersdecking.com/free-consultation/schedule/) ##### Anatomy of a deck #### Footings Concrete columns below grade(the ground) that support the posts and, thus, the deck. On sites where the soil freezes and thaws, concrete is poured in an above-grade form and a cylindrical hole. Footing depth requirements vary from area to area. ### Posts Timbers (usually 4in or 6in) set vertically to support the deck framing. Posts are used on all but the shortest decks. The posts can be cut off below the deck surface, or they may rise above the surface to provide support for railing. Posts may rest on top of concrete footings or they can be set plumb in the hole before the concrete is poured. ### Post Anchors Metal framing connectors that attach posts to piers or footings. They raise the base of the posts slightly above the top of the footing, protecting them from water damage. ### Girders/ Beams Boards directly connected to the posts to create a surface for joists as a foundation for the framing. ### Ledger A board (usually 2in stock) attached to the house to support one side of the deck. ### Joists Horizontal framing boards (usually 2in stock) fastened on top of the beam or flush with the ledger to support the decking. Header joists are fastened to the ends of the deck's interior joists. Rim joists or end joists are the outermost joists perpendicular to the ledger. ### Joist Hangers Metal fasteners that allow you to fasten the joists in place without noticing the ends of the board. A joist hanger secures a joist to a ledger or rim joist. ### Bridging Short pieces of lumber between joists that strengthen the framing. They are designed to prevent the joists from twisting. ### Treads/ Steps The horizontal, stepping surfaces of a stairway. ### Risers Boards covering the vertical spaces between stairway treads. Although shown in the drawing, risers are often omitted on decks and other exterior steps. ### Stringers Long, diagonal framing boards (usually 2in x 12in) that support stair treads. The stair steps are attached to and supported by the stringers. ### Decking 2 inch or 1 1/4 inch boards attached to the joists to form the deck floor. ## Book Your Free Deck Consultation ## Schedule Your Free On-Site Consultation LIC: #3BROTBD817J6 Monday-Saturday 7am-7pm [info@3brothersdecking.com](mailto:info@3brothersdecking.com?subject=&body=) #### Bellevue, WA (425) 999-2048 3220 118th Ave SE, Suite 105 Bellevue, WA 98005 [Deck Builder in Bellevue](https://3brothersdecking.com/locations/bellevue/) #### Coeur d'Alene, ID (425) 999-2048 3390 W Hayden Ave Hayden, ID 83835 [Deck Builder in Coeur D'Alene](https://3brothersdecking.com/locations/coeur-d-alene/) #### [Sandpoint](/sandpoint/) (425) 999-2048 502 Cedar St, Suite 100 Sandpoint, ID 83864 [Deck Builder in Sandpoint](https://3brothersdecking.com/locations/sandpoint/) [View All Service Areas](/locations/) ## Your Trusted Deck Builder & Exterior Remodeling Partner Serving Western Washington, including the Greater Seattle Area, and Northern Idaho, 3 Brothers Decking is your go-to expert for custom deck design and professional installation.
