IronAsh External Timber

Australian Sustainable Hardwoods (ASH)

H3 treated Australian Oak (ASH's brand of Tasmanian Oak) – as beautiful as it is durable and guaranteed to perform.

Treated to H3 classification (per AS1604 Specification for Preservative Treatment), IronAsh can be used externally in partnership with Australian Oak to allow continuous flow of timber design from inside to out.

Because of the stunning blonde tones of IronAsh timber, you can stain and paint it to almost any colour. The water-based H3 treatment doesn’t affect the colour of the timber, which means that you can easily match internal joinery with external applications.

IronAsh is a great choice to finish any project. It can be easily cut, stained and painted on site. The IronAsh range offers an affordable timber choice that is stable and readily available.
