When it comes to constructing a terrace, there are several factors to consider. From the type of wood used to the spacing between joists, it's essential to plan your project correctly to ensure that your deck is safe and secure. In this article, we'll discuss the different elements that determine the maximum span of floor decks between beams. The size of the deck, the type of wood used, and the design of the platform all play a role in determining the maximum distance between joists and beams.
Generally speaking, most decks use a 16-inch center spacing for joists. However, if you're looking to increase the strength of your platform or increase the maximum allowable span of your joists, you may need to reduce this spacing to 12 inches. When it comes to the distance between two roof beams, this is measured in inches “in the center”, commonly abbreviated as “OC”. For example, if you draw a line in the center of two joists and measure the distance between them as 16 inches, that measurement is 16 inches in the center.
If your deck won't be more than 6 feet from the ground, it's recommended to space support beams no more than 12 feet apart. Additionally, most decks only require one beam along the outer edge of the platform (a ledger bolted to the house supports the other end).The weight load on your structure will also influence the maximum distances of your joists and beams. Each roofboard manufacturer submits their roofing material to extensive independent tests to find out what is an appropriate spacing between joists. For instance, if you're installing your deck at a 45-degree angle, most composite deck brands suggest 12 inches of OC. It's worth noting that there is an alternative framing method that allows you to install your terrace perpendicular to the house and make it independent.
