Welcome to the Timber Joists category at Build4Less, where we offer a comprehensive range of high-quality timber joists suited for a variety of construction and carpentry projects. Our selection includes both treated and untreated options in various dimensions to meet your specific needs.

Treated C24 Carcassing Timber

Our treated C24 carcassing timber is a top choice for structural applications. The treatment process enhances durability, making these joists ideal for use in areas prone to dampness or where additional strength is required. These joists come in several sizes, including 47mm x 100mm, 47mm x 125mm, 47mm x 150mm, 47mm x 175mm, and 47mm x 225mm, all at a standard length of 4.8m. The variety in width and depth allows for tailored solutions in construction, particularly for floor and ceiling joists, roofing, and framing.

Untreated C24 Carcassing Timber

For projects where treated timber is not necessary or a natural finish is preferred, our untreated C24 carcassing timber is an excellent choice. These joists offer the same high-quality structural integrity as their treated counterparts but are more suited for indoor applications or where timber will not be exposed to moisture. Available sizes include 47mm x 100mm, 47mm x 125mm, 47mm x 150mm, 47mm x 175mm, and 47mm x 225mm, all in 4.8m lengths. These are ideal for interior framing, non-load-bearing walls, and other general carpentry projects.

Untreated C16 Timber Carcassing

In addition to our C24 range, we also offer untreated C16 timber carcassing. This is a cost-effective alternative for less demanding applications where a lower grade of timber is sufficient. The 47mm x 100mm x 4.8m size caters to a range of uses, including light framing and non-structural work.

Selecting the Right Timber Joist

When choosing timber joists, consider the following factors:

  • Treatment: Treated timber is essential for outdoor use or in damp environments, while untreated timber is suitable for dry, indoor applications.
  • Strength Grade: C24 timber is stronger and more durable, ideal for structural work, whereas C16 is more economical for non-critical structures.

  • Size and Load: Ensure the dimensions of the joist match the load requirements and spacing of your project.

     

Our range at Build4Less caters to both professional builders and DIY enthusiasts, offering flexibility and reliability for your construction needs. Whether you're building a new home, adding an extension, or undertaking a renovation project, our timber joists provide the structural integrity and quality you need.
