Scots pine is a softwood originating from northern Europe and Asia, the sawn form of which is used in general construction, flooring, paneling and interior joinery. Treated with preservatives it has also been used for poles and pit props.
The sapwood of Scots pine is 50-100mm wide, creamy white or pale yellow, and readily identified from the yellow-brown to reddish brown heartwood. Its texture is relatively fine and the grain is usually straight. The growth rings are prominently marked by the darker, denser summerwood. The knots are usually grouped, whereas in White Baltic Pine they are much more randomly distributed. The wood is resinous; it is of low durability and not susceptible to lyctid borer.

The heartwood of Scots pine is yellow-brown to reddish brown, and can be easily distinguished from the creamy white to pale yellow sapwood. The sapwood is 50-100mm wide. The grain is commonly straight and the texture relatively fine. Usually the knots are grouped, as distinct from white Baltic pine, where the knots are much more randomly distributed. The wood is resinous and the growth rings are marked by the darker, denser summerwood.
Scots pine is used for general construction, paneling, flooring and interior joinery. Treated with preservatives it can also be used for poles and pit props.
