Our range of 5x2 timber is perfect for structural work where extra width is required. Ideal for joists, roofing, and general construction, this size offers excellent strength and versatility for a wide range of projects.

Why choose 5x2 timber?

5x2 timber is commonly used for:

  • Roof joists and rafters
  • Decking frames
  • Floor joists and supports

Its size gives extra stability compared to 4x2 timber, making it a reliable choice for heavier-duty tasks.

What is 5x2 Timber in mm?

5x2 timber is around 47mm x 125mm. This makes it a practical option for builders and DIY enthusiasts who need a sturdy timber for load-bearing applications.

Treated timber for added protection

For outdoor projects or areas exposed to moisture, opt for treated timber; this is pressure-treated to resist rot, decay and insect damage. It’s ideal for decking, garden structures, and any job that needs long-lasting durability.

We stock 5x2 treated timber in a variety of lengths. Whether you’re building a strong frame or upgrading outdoor structures, our timber provides quality, strength, and reliability.
