The AS 4440:2004 standard outlines the requirements for the bracing, connection, and installation of nail-plated timber trusses in roof structures, specifically for typical applications. This standard serves as a guideline to ensure that the installation of timber trusses in roof structures meets certain safety and structural integrity standards.

The standard emphasizes the importance of proper bracing to ensure the stability and strength of the roof structure. It provides guidelines on how the trusses should be connected and secured using nail plates, which are metal plates with pre-punched holes that are nailed into the timber members to create load-bearing connections. The standard also addresses the installation process, providing instructions on how the trusses should be positioned, aligned, and fixed in place.
