Timbers

Timber is a natural, reusable, recyclable and sustainable product. S&A Stairs acquire timbers from accredited and responsible contractors and mills which follow the strictest of private forest management practices to sustain a viable industry without placing unrealistic demands on our resources. A hardness rating is provided for all timbers as a measure of their resistance. Hardness is an important consideration when deciding on a timber for your stair.

Below is a more detailed breakdown of our timber varieties and their hardness ratings...

Victorian Ash

Alpine and Mountain Ash are tall trees found in cooler, high altitudes. This wood is a pale pink to yellow brown in colour. Both species are fast growing and often show clearly distinguishable growth rings. The grain is generally straight with occasional waviness.

(Hardness Rating - 4.5)

Blackbutt

One of the most important hardwoods of Australia. It is a tree of striking appearance and can grow to 75 metres in height with its straight trunk rising to at least half its height. The wood is renowned for both its strength and versatility of application, with attractive colouring from cream to pale brown.

Brushbox

Brushbox is a large hardwood that tends to be found on the edge of rainforests. The heartwood ranges from rich reddish brown through lighter browns to pinkish greys.
