Ironbark Timber

What is Ironbark Timber?

Ironbark timber is a premium native Australian hardwood comprised of several different species with a wide range of applications and uses from industrial construction to house framing and flooring. Ironbark timber is a hard-wearing and durable timber that is borer and termite resistant.

Its name comes from the apparent resemblance of its bark to iron slag, the by-product left after the metal has been separated from its raw ore.

The colour of ironbark timber varies anywhere from dark red, dark brown and pale brown. However, common ironbark has a reddish tone.

Why Ironbark Timber?

Ironbark timber is a hard-wearing and durable timber that is borer and termite resistant. Additionally, ironbark timber has a Class 1 Durability rating. As the highest timber durability raring, ironbark is projected to last for 50+ years in a fully protected area and 50+ years outside above the ground. Class 1 timber will last 25+ years if it is in the ground, such as decking and patio poles.

Not only is ironbark durable, but it is also extremely heavy, making it ideal for structural use. It is primarily used in timber decking, flooring, handrails and outdoor timber construction.

Ironbark Timber:
The Benefits?

Due to its incredible weight and density, it is not a timber that is often used for smaller, precision work and projects. But rather larger construction projects. However, Ironbark Timber provides various exciting construction benefits.

Strength: Due to its durability, the hard-wearing Ironbark is ideal for high traffic areas making Ironbark decking and flooring popular in commercial and domestic builds. It is the ideal timber for large construction projects, such as house framing, cladding, lining and internal and external flooring.

Rot and Insect Resistant: Ironbark timber has high-density levels with a strong natural resistance to lyctid borers and termites. This makes it a great option when building in areas prone to termites and other natural borers.

Degree of Fire Resistance: Ironbark Timber is the recommended timber for construction in bushfire-prone regions, as it is not easily flammable and fire-resistant.

Style: The natural appeal and range of colours of Ironbark lead to some stunning architectural and design applications.

Gowan Lea Timbers

Known for our hardwoods, our timber supplies include Ironbark and other timber and building product lines such as pine framing, plywood, engineered timber, and fibre cement products.

Our History

We began Gowan Lea Timbers over 25 years ago when we decided to open a small retail yard for timber needs on the rapidly growing Sunshine Coast of Queensland. We started with two staff members, a forklift, a flat-bed truck, and an office in a shipping container, and as we grew, we gained a solid reputation for boasting the best hardwood around. 

It didn’t take us by surprise. Our mill—Gowan Lea Sawmilling Company—had been operating for over 40 years and was already a well-respected wholesaler of premium quality western QLD Spotted Gum and Ironbark products. However, when the Queensland State Government bought out and closed Gowan Lea Sawmilling Company through a Regional Forestry Agreement process in 2007, the retail timber yard was left without a supply of the premium hardwood that our business relied upon.

It was then we entered into a productive relationship with Mary Valley Timbers, a green hardwood sawmill near Gympie, who had a similar focus on quality and cut 95% Spotted Gum and Ironbark.
