What is American 'white' Ash?

American 'white' Ash Introduction: timber is mainly used for interior furniture and joinery, particularly where bending-strength is required. The colour of Ash boards will vary from a white appearance through to brown.

The natural order Oleaceae includes a number of species of the genus Fraxinus or ash, whose timber is characterised by good strength elasticity, toughness, stiffness and hardness, allied to relatively light weight. The following are the principal species found in North America:
Black ash Fraxinus nigra
Green ash Fraxinus pennsylvanica
White ash Fraxinus americana

American Ash timber is imported in FAS grade in imperial thicknesses of sawn 1", 1 ¼", 1 ½", 2", 2 ½", 3" & 4". Kiln dried imported packs normally contain random widths from 4" to about 9" and are in predominantly even lengths i.e. 8', 10', 12' as this is the standard method of American hardwood production. Occasionally we are able to obtain other lengths up to 14' long and also premium widths.
