Decking Parts And Structure Explained

Decks come in wide ranges of shapes designs, large and small. One thing that stands out among the different sizes and looks is that the structure or look of a deck is the same. For DIY'ers here is a valuable breakdown of all deck parts or structures needed to ensure a solid, long lasting and safe deck.

So what are the parts of a deck? What are they made of?

Knowledge is strength. Acquaint yourself with the various names and parts of your deck. Just think how you'll impress your friends and spouse as you order that part by name at your building supply.

Let's begin identifying and naming each structural part of a deck.

Boards used in the construction of decks usually are pressure treated wood because pressure treated is great for strength and longer life in the elements. These boards come in 2x6, and larger structural sizes, that hold the deck up. When constructing a deck other names you will become familiar with are ledgers, beams, posts, and joists.

Topside parts of the deck include the actual decking , rails, stairway, and decorative fascia usually 2x6 just below the deck running horizontal. The parts you see topside are usually in redwood, cedar or for example if its a composite deck, then you would probably use the manufacturer's composite railing kit and posts that compliment the brand of decking you have chosen.

Lets Identify the Deck Ledgers: They are used to secure a deck to an existing house. It's used to support one end of your joists. Joists: These are usually 2x6 boards attached at both ends of the deck. Joists are what the deck boards are attached to, either by nailing, screwing or T-clips. These joists are secured to the header joist on one end and to the ledger on the other end.

Concrete Footings; How is the deck supported? By concrete footings. The footing is formed by pouring concrete in the ground and hence allowed to dry. While drying some will secure a cement block of sorts with wood on top of this to nail in their 4x4 posts. Another way to attach posts is with metal post anchors made of galvanized steel.

Posts: These are attached to the concrete footings vertically 4x4's.

Beams: ( 2x8 or 2x10 wood supports) Called the main support system which is fastened to the deck posts underneath the deck.

Railings Terms you will hear are balusters, posts, railing and the cap. Balusters and posts you'll find are attached to the header and outside joists of the deck. The height of of the rails are usually 24- 34 inches high- check with local building codes.

Stairs: Made of 2 stringers and a number of what is called treads attached with cleats (metal) to the side of a deck.

That's it for now.....Happy Deck Building.
