What size joists are required for a deck?
What size joists are required for a deck?
Commonly used joist sizes are 2-by-6, 2-by-8 and 2-by-10. For example, when you space joists 16″ apart — which is standard for residential decks — a deck spanning 9 1/2′ would require 2-by-6 joists, a 13′ deck would need 2-by-8 joists and a 16′ deck calls for 2-by-10 joists.
What should I use for deck joists?
Pressure-treated lumber is ideal for deck framing. We also recommend using joist tape or a wood protectant to help shield cut ends from moisture damage.
How do you fix joists in a rotten deck?
Repair and reinforce joists that have soft, discolored areas with rotted wood putty. Apply a thick coat of clear sealer to the damaged joist. Let it dry, and then apply a second coat of sealer. Cut a reinforcing joist from pressure-treated lumber.
How much does it cost to replace deck joists?

| Rail replacement (wood & metal) | $125.00 – $145.00 per lineal foot |
| Decking replacement | $12.00 – $15.00 per LF or approx $30.00 per SF |
| Stringer replacement | $245.00 – $375.00 per stringer |
What kind of joist do you need for a deck?
Joists are the repeated structural members that are used to build a deck frame. The minimum size joist to be used in deck construction depends on the number of footings and beams that will be installed. What Is a Beam?
What’s the difference between a joist and a beam?
Joists are the repeated structural members that are used to build a deck frame. The minimum size joist to be used in deck construction depends on the number of footings and beams that will be installed. What Is a Beam? A beam is the main load-bearing element for the structural soundness of your deck’s roof.
How many beams should be spaced on a deck?
To properly space deck beams, you need to consider the joist span. The limitations of how far a joist can span determines just how many beams you’ll need. Joists spaced the standard 16 inches apart can span 1.5 times their depth in feet.
What are the different types of deck beams?
There are two types of deck beams to consider: flush beams and drop beams. A drop beam is positioned under the joists to bear the weight of the frame. A flush beam is positioned at the same level as the joists. With a flush beam, the joists are attached to the beam using joist hangers.
How far can a deck beam span?
The beam span for most deck beams is less then 16 feet (4.87 meters) but can be as small as 8 feet (4.87 meters) depending on the thickness of the beam. These special beams support the weight of the main floor on the deck are an essential for overall structural integrity.
What is deck support beam?
How to Size a Deck Beam. A beam is a solid structural member that is supported by posts and footings that accepts and transfers the load from joists. Once you know the distance between support posts and the length of the joists that will be supported you can determine the required size by checking our beam-sizing chart.
What is deck post spacing?
The size of the deck directly affects the spacing of the support posts. While a 16-foot-by-16-foot backyard deck for recreational purposes, such as an outdoor kitchen and general lounging, may only require deck posts spaced every 7 feet, a larger deck may require that the spacing be narrowed down to within 5 feet.
