Treated pine is commonly used in framing applications in Australia due to its affordability, durability, and availability. Treated pine framing is suitable for use in both residential and commercial construction projects and is used for wall framing, roof trusses, and other structural applications.

In Australia, treated pine framing is typically treated with preservatives to protect it from termites and fungal decay, and to increase its service life. The level of treatment required will depend on the intended use of the timber and the location of the project. H2 treated pine is suitable for above-ground use in protected environments, while H3 and H4 treatments are designed for use in outdoor and in-ground applications, where the timber is exposed to moisture and/or the risk of termite attack is higher.
