Lumber (American English; used only in North America) or timber (used in the rest of the English speaking world) is a type of wood that has been processed into beams and planks, a stage in the process of wood production. Lumber is mainly used for structural purposes but has many other uses as well. There are two main types of lumber.
The most readily available plantation timbers in Australia are softwoods such as Hoop Pine, Radiata Pine and Slash Pine, the two latter of which are introduced species.Regrettably, there is an undersupply of plantation-grown Eucalypt and other hardwood species on the Australian market.Many eucalypt plantations growing in NSW-apart from mainly bluegum and blackbutt-are generally not yet mature, or their trees are not currently being processed as sawlogs.nofficial reports indicate, however, that (treated) sewage-fed hardwood species can equal the rapid growth rates of Radiata Pine. Australian hardwood plantation timbers are mainly used for low-value applications such as pulp and paper products, their fibre being considered superior to that from native forest trees.
