Silvertop ash is a large, moderately durable Australian hardwood that grows in the southern and central coast and tablelands of New South Wales, eastern Victoria and north eastern Tasmania. It is also known as ‘coast ash’ due to its occurrence along the coastal areas of the cooler eastern states.
Of medium texture, silvertop ash has an interlocked grain and with noticeable growth rings. The heartwood is brown, sometimes pinkish and the sapwood is narrow in appearance. Gum veins, markings from pinhole borers and pencil streaks also distinguish the appearance of silvertop ash.
Care needs to be taken when drying silvertop ash, because of its proneness to surface checking on the tangential surface. It is also slow to dry.
Silvertop ash provides good fire resistance, and is one of seven hardwood timber species that was found to be suitable by the Building Commission in Victoria for home construction in bushfire areas (provided it has a thickness greater than 18 mm).
It is mainly used for general construction, but is also used for flooring, furniture, handles, joinery, fence posts, cases and chemical pulp.
