Wood Joists

Wood Joists: The Essential Framework for Your Terrace

The wood joist is the indispensable structural base for any terrace installation, whether made of natural wood, composite wood, or even tiles on pedestals. Choosing the right joist ensures the stability, longevity, and safety of your project, whether it’s a new build or a renovation. At Plots Discount, we offer a wide selection of wood joists suitable for all types of construction sites and requirements.

Selected Wood Types for Every Need

Our range addresses diverse projects with a selection of different wood types:

• Class 4 Autoclave Pine Joist: Ideal for outdoor environments, treated pine offers excellent resistance to moisture, fungi, and insects. This autoclave treatment ensures long-lasting durability, even in direct contact with the ground or in humid areas.
• Exotic Wood Joist: Valued for its strength and stability. Exotic species such as Ipe or Cumaru provide high mechanical resistance and remarkable longevity, easily withstanding demanding weather conditions.
• Composite Wood Joist: Recommended for composite decking, combining dimensional stability, no warping, and a uniform appearance.
• Aluminum Joist: An alternative to wood joists, designed for maximum structural stability, especially on uneven supports or adjustable pedestals.

Sections, Dimensions, and Technical Constraints

The cross-section of wood joists depends on the intended use and span. We offer standard sections: 40x60 mm, 50x70 mm, or 45x70 mm, suitable for various decking types, including traditional wooden boards or composite planks. The section choice determines the mechanical strength and long-term stability of the structure.

Installation can be on concrete slabs, adjustable PVC pedestals, or stabilized ground. Proper ventilation between the joist and the support is essential to protect the wood from moisture and extend the structure's lifespan.

Compatibility with Wooden, Composite, and Tile Decks

Wood joists are compatible with:

• Natural wood decks (pine, exotic wood, or other suitable outdoor species)
• Composite decking, with recommended composite or aluminum joists for enhanced stability
• Tile decks on pedestals, thanks to adjustable pedestal heights and easy bracket fixation

For high-load areas or projects requiring maximum stability, a reduced spacing between joists and/or aluminum joists may be considered.

Best Practices for Installation and Structural Optimization

To ensure the longevity of your terrace, we recommend:

• Following the recommended spacing according to joist section and board type (generally 40–50 cm for wood, 30–40 cm for composite)
• Ensuring proper ventilation beneath the structure using adjustable pedestals or shims
• Applying protective treatment at cut ends for pine wood
• Using appropriate accessories, such as stainless steel brackets, invisible fasteners, or sealing strips

These practices optimize the lifespan of your joists and the stability of your wooden terrace, ensuring a safe and aesthetically pleasing result over time.
