Composite decking is one of the most lasting and secure flooring options. Composite materials consist of recycled plastic and recycled wood. It is both durable and keeps the natural beauty of the wood. Now, though, homeowners are opting for composite decking materials. Now, let’s discuss the optimal joists required to construct the composite decking.

To make a deck safe and long-lasting, however, you need more than simply robust materials. The construction of a floor, from the foundation to the finish, is crucial. Planning the construction process is equally as crucial as selecting the materials. So, what is the first step while creating a deck?

Joist frame

One of the initial steps in deck construction is creating a solid foundation. In comparison to other decking materials, composite materials require less effort for the deck’s foundation. You only need to construct a sturdy joist frame as the deck’s base or support. Decking construction does not require a complicated foundation or a concrete base.

Yes, WPC decking requires easier substructures than conventional materials. Nevertheless, you will not settle for mediocrity. Keep in mind that your decor relies on these frames. Inattention to these particulars may result in bad outcomes.

Which joists are ideal for composite decking?

There are numerous factors to consider while selecting joists for your WPC decking boards. Trim frames, including trim joists, are the structural backbone of a floor. To get the most out of your floor, you must lay the best possible foundation. To accomplish this, you must locate the most suitable joists.

The advantages of composite joists are identical to those of composite decking. It is highly waterproof, mildew-resistant, and rot-resistant. In addition, the composite joist has the benefits of durability and long service life. When compared to pressure-treated wood, composite decking offers greater convenience.

Consequently, when you utilize composite decking to construct your outdoor living space, you will enjoy the following benefits: We also recommend using composite joists to construct deck frameworks for outdoor decks.

How can joists be used to construct deck frames?

The frame’s height from the ground

When deciding the material to choose, you need also to consider the height of your deck. For subfloors and patios, the frame must be protected from moisture and decay.

Therefore, if you use pressure-treated wood, you must perform a thorough job of water- and corrosion-proofing. Avoid major safety issues with the outside deck caused by the frame’s deterioration. Therefore, composite joists are the best option.

Strut Spacing

When installing joists, one must also pay attention to the joists’ spacing. It is the distance between the centers of one joist and the other. Even with the finest materials, the effect will not be attractive if the beams are not separated properly.

The normal spacing in residential areas is 16 inches. While safety rules normally require 12 inches for commercial decks, Some do 24″ spacing. The planks are weaker the more space there is between the joists. Therefore, if you like a strong deck, opt for a closer joist spacing.

However, it is best to adhere to the manufacturer’s or supplier’s instructions. Additionally, you will need to adhere to the construction codes of your country.

Girder thickness

The thickness of the joists might also influence the results of your deck construction. Similar to spacing, joist thickness will impact the overall floor capacity. Decks are strengthened with beams that are thicker and more robust.


Regardless of the type of material chosen for the outdoor deck. A sturdy and long-lasting deck frame is essential. A quality deck frame can extend the life of an outdoor deck. So that you do not have to worry about your family’s safety.
