Scandinavian Pine (also referred to as ‘redwood’ to differentiate it from ‘whitewood’ such as Spruce) is imported from Sweden, Finland and Russia. The grades vary for different uses. Knots are common but their size and quality vary according to the part of the tree from which boards are converted.
It should be noted that the timber is kilned prior to shipping but the moisture content is often about 18%, and therefore higher than most kiln dried hardwood moisture contents.
The diameter of such pines normally result in board widths of 100mm - 225mm.
Edge-glued panels are imported in large volumes for pine furniture manufacturers, with lamination widths usually about 45mm.

Sapele from West Africa is a reddish-brown hardwood. Although some parts of the Sapele logs will produce straight-grain or ‘quartered’ effect, generally it has a more random grain appearance. It is used for numerous mahogany-looking products, for example conservatories, door frames and solid wood doors, furniture and counter tops.
It is available kiln dried in thicknesses 26mm, 32mm, 38mm, 50mm, 63mm, 76mm and 100mm. Random widths range from 100mm to about 400mm and lengths 2m to about 5m.
It is essential to specify the narrowest and shortest dimensions to optimise the lower priced sizes.
