Pressure-Treated Joist

Pressure-Treated Joists: A Technical Choice for Deck Frameworks

The pressure-treated joist is a key element in any deck framework, whether for wood, composite, or softwood. Its function is essential: it provides the structure and stability of your deck by forming the base on which the boards are fixed. Mainly made from pressure-treated pine, but also available in Douglas fir, spruce, or fir, it is deeply treated to resist external aggressions, moisture, and insects over the long term.

Joists Suited to Every Structure

Available in various sections, lengths, and classes, pressure-treated joists are suitable for all types of decks: natural wood, composite, or exotic wood. Class 4 is recommended for outdoor use with frequent exposure to moisture, while Class 3 is suitable for less exposed environments. A Class 4 pressure-treated Scots pine joist is ideal for a durable garden layout or pedestal deck.

Compatibility with Adjustable Pedestals and Elevated Decks

A pressure-treated joist installs perfectly on adjustable polypropylene pedestals, allowing precise leveling, whether the base is concrete, gravel, or an old slab. This setup avoids direct contact with the ground, prolonging the wood’s lifespan and simplifying framework installation, particularly in renovations. The joists are compatible with all types of boards: wood, composite, or pressure-treated pine for decking.

Tips and Best Practices for Installing a Pressure-Treated Joist

Preparing the Support for the Framework

Before installation, ensure that the support (concrete slab, gravel, adjustable pedestals) is flat, stable, and well-draining. Place the joists with spacing adapted to the thickness of wooden or composite decking boards. For high-exposure areas, opt for thicker sections and higher class.

Recommended Fixings and Accessories

Joists should be anchored using stainless steel fasteners, resistant to weather and corrosion, ensuring reliable long-term attachment. Bitumen strips placed on top of the joists reduce water stagnation and extend the lifespan of your deck.

Durability and Maintenance

Pressure-treated joists have a long lifespan, often exceeding 15 to 20 years with proper maintenance. Regular inspection of the framework and cleaning between boards optimize the strength and performance of your outdoor layout.
