Composite decking joist
Different types of joists for composite decking: a key choice for your structure
At the heart of any composite decking project, the choice of joist is crucial. The composite decking joist ensures stability, longevity, and installation quality, contributing to the overall durability of the project. At Plots Discount, we offer a full range of composite, wood, and aluminium joists, suitable for all types of decking structures, whether residential, commercial, or for elevated decking on adjustable pedestals.
Composite joist: balance between durability and ease of installation
Made from composite wood, composite joists combine moisture resistance with mechanical stability. They effectively support composite decking boards and offer a longer lifespan than raw wood, with excellent resistance to weather and temperature variations. Their simple installation, low maintenance, and structural reliability make them a reference choice for pedestal or concrete slab installations.
Aluminium joist: unmatched strength
For environments requiring maximum strength and precision, such as high-traffic areas or professional projects, the aluminium joist provides optimal structural support. Resistant, lightweight, and perfectly straight, it ensures even load distribution and maintains the recommended slope for rainwater drainage. Compatible with all composite boards and invisible fixing systems, it guarantees exceptional durability for your composite decking structure.
Wood joist: a traditional choice
The wood joist, although classic in decking construction, remains popular for natural ground projects or limited budgets. However, it requires class IV treatment for moisture resistance and periodic maintenance for durability. Wood joists are less frequently used with composite boards but can suit certain configurations.
