American White Ash


American ash is similar in appearance to European ash. The sapwood is light coloured to nearly white and the heartwood varies from greyish brown to light brown, to pale yellow streaked with brown. The wood is generally straight grained with a coarse uniform texture. The degree and availability of light coloured sapwood, and other properties, will vary according to the growing regions. for example, southern ash lumber will be faster grown and contain more sapwood and therefore, a higher percentage of white colour, but compared to Northern ash, it has a more open texture and grain. 

American ash can comprise a number of commercial sub species and is available in a wide range of grades and specification as lumber and veneer.   

Durability: Non-resistant to hardwood decay. The heartwood is moderately resistant to preservative treatment.

Main Uses: Furniture, flooring, doors, architectural interiors, high class joinery and moulding, kitchen cabinets, panelling, tool handles, sports goods and turning. A versatile, good looking wood, offreing great value for a wide range of joinery and furniture applications.

Working Properties: Ash machines well, is good in nailing, screwingand gluin, and can be stained and polished to a very good finish. It dries fairly easilywith minimal degrade, and good stability means there is little movement in performance. 

Other info: Light brown flecks or mineral streaks, sometimes referred to as a glassworm, are common and are treated as a natural charecteristic and not considered as defects.
