What Are the Structural Components of a Raised Deck?

Four main structural components make up a raised deck. These include a Balustrade, a Ledger, a Joist, and concrete footings. These components are discussed in detail to understand their purpose better. Read on to learn about these essential parts of raised decking supports.


While handrails and balustrades are often made of timber, they can be susceptible to the elements. Timber is particularly vulnerable to the effects of rain and salt, so it is essential to treat the timber with weather-proof paint or stain. The same applies to railings made of steel or concrete.

To be safe, balusters and guardrails should be installed with adequate spacing between them. The spacing should be at least four inches. A four-inch space is enough to fit a four-inch-diameter ball. This will prevent a baby’s head from getting stuck in the railing.

Balustrades are a standard feature on a raised deck. Depending on its size, it can be made of wood or other materials. The balusters are the decorative elements that connect the posts and railing. The balusters are usually evenly spaced and supported by posts. Balustrades are also an excellent way to define space.


A raised deck has several structural components: the ledger, end joists, deck framing, and siding. The ledger supports one end of the deck joists and is the deck’s foundation. It is essential to install the ledger early in the construction process to make it easier to lay the foundation. There are several different methods for installing a ledger.

If you’re installing a new deck, consider installing pressure-treated plywood spacers behind the ledger. This will help prevent moisture from entering and causing rot. Also, use caulk to fill any holes before inserting bolts. This can prevent leaking into the house, rotting, and insects from ruining the decking material.


Joists are structural components of a deck that runs above ground level. They support the deck’s decking and can be installed at different levels. They are commonly made of galvanized steel or stainless steel. They are secured to the beam with structural fasteners. There are many different types of joist hangers. Some are used to connect joists to a beam, and others are used to fasten the joists directly to the face of the beam.

The first step is to cut the joists to the proper height. Mark the joists with a sharpie or construction pencil to determine the proper spacing. The spacing should be 16″ on the center. After cutting joists, install them one at a time, connecting them 16″ on the center. Use a chalk line to mark the locations of hanging hardware.

Concrete Footings

Raised decks can be built in many different styles, and there are many ways to construct a raised deck’s structural components. The first step is to create the footing. Traditionally, footings were a post buried in the ground and supported by a concrete pad. However, over the years, footings have taken on many different forms. They’ve become a more sophisticated design that varies according to weight and soil tests. In addition, they’ve also begun to be poured above grade, which prevents freezing water from collecting in the ground.

Most building departments require footings to support the deck. You should check with the building department to ensure the deck will be safe to use during winter. You should ensure that the footing depth is below the freezing point of the ground.
