seasoned timber refers to timber that has been dried to a moisture content between 10% and 15% . This process, known as seasoning, involves removing the bound moisture contained in the walls of the wood cells to produce timber that is stable and less prone to warping or splitting

Characteristics of Seasoned Timber

Seasoned timber has several advantages, including:

• Cross-section dimensions that remain almost constant
• Improved stability and reduced risk of warping or splitting
• A moisture content that is in equilibrium with internal environments in many parts of Australia

Moisture Content Requirements

In Australia, seasoned timber is typically supplied with a moisture content not exceeding 15% . This ensures that the timber is suitable for use in construction projects and meets the required standards for stability and performance.

Grading and Classification

Seasoned timber is graded and classified according to its strength and moisture content. In Australia, the stress grade classification system is used to derive the strength classification for structural timbers . Seasoned timber is typically denoted by the prefix "SD", which indicates that it is seasoned or dry timber .
