What is Structural Graded Timber?

Structural graded timber is essential for construction projects where strength and reliability are paramount. At Ecochoice, we supply high-quality, sustainably sourced structural timbers that meet industry standards and provide excellent performance in load-bearing applications.

Graded timber is classified into C (softwood) and D (hardwood) strength classes, ensuring the right material is used for structural integrity and durability.

C-Class vs D-Class Strength Ratings

• C-Class (Softwood Timbers) – Typically used for general construction, C-class timbers (such as C16 and C24) are cost-effective and widely available. They are suitable for beams, joists, and structural frameworks where moderate strength is required.
• D-Class (Hardwood Timbers) – Hardwoods are denser and more durable, classified as D30, D40, and higher. These timbers are commonly used in heavy-duty structural applications such as bridges, marine works, and railway sleepers.

Popular Structural Hardwood Timbers & Strength Classes

1. Oak (D30 & D40) – Oak is a highly durable and strong hardwood, ideal for beams, trusses, and heritage restoration projects.
2. Ekki (D70) – One of the toughest timbers available, Ekki is perfect for marine and civil engineering projects due to its extreme density and resistance to decay.
3. Greenheart (D70) – A high-strength timber used in heavy-duty construction, piers, and marine structures, thanks to its exceptional durability and water resistance.
