Starting From Just $100.00

Grey Ironbark is one of the most durable timbers available in Australia, known for its density, deep reddish-brown tones, and long lifespan. It’s a popular choice for flooring due to its impressive strength, dense structure, and ability to withstand heavy use over long periods. With a Class 1 durability rating and 14.0 kN Janka hardness score, Grey Ironbark performs exceptionally well in busy homes, high-traffic commercial spaces, and any environment where long-term durability is a priority.

Product Description

Standout Features of Grey Ironbark Flooring

Tough Timber that Handles Heavy Use

Grey Ironbark has built a reputation for being one of the hardest flooring timbers on the market. It’s dense and solid underfoot, which gives it great resistance to dents, scuffing, and day-to-day wear. That makes it well-suited to hallways, open-plan living areas, and commercial fit-outs that see a lot of foot traffic.

With a Janka rating of 14.0 kN and a density of around 1120 kg/m³, you’re working with a product that’s built to last.

Natural Grain and Colour Variation

This timber ranges from dark reddish-browns to deep chocolate shades, often with a slight grey undertone depending on the board. The grain is typically tight and interlocked, which helps it present a consistent finish once installed. It’s a good fit for projects that need a stronger visual presence without looking overly busy or patterned.

Performs Well in Harsh Environments

Grey Ironbark holds a Class 1 durability rating, meaning it resists both decay and termite activity. It also meets the BAL 12.5 bushfire rating, making it suitable for properties in areas with a moderate fire risk. These features give it a reliable performance profile, particularly in exposed or rural settings.

Sizes and Profiles

We supply Grey Ironbark boards in the standard size – 130 x 14 mm.
All boards are designed to fit together easily with tongue and groove edges. They’re already prepared so you can install them directly onto the floor, on top of plywood, or over battens, ensuring a straightforward installation and a smooth finish.

Low-Maintenance Requirements

Because it’s so dense, Grey Ironbark doesn’t need much upkeep. A sweep or vacuum followed by a damp mop is usually enough to keep it clean. You won’t need to recoat or oil it often; the finish tends to hold up well over time.

We’re Here to Help

Janka Rating

What Is the Janka Rating?

The Janka rating is a way to measure how hard a timber is, specifically, how much force it takes to push a small steel ball halfway into the wood. The number you get is shown in kilonewtons (kN). A higher Janka score means a harder, more durable timber. Builders and floor installers use it to work out which timbers hold up better in busy areas.

Here’s a rough guide to how some timbers sit on the scale:

  • Brazilian Walnut – around 16.0 kN
  • Spotted Gum – roughly 11.0 kN
  • Tasmanian Oak – about 5.5 kN
  • Radiata Pine – close to 3.0 kN

Keep in mind: these values can vary depending on moisture content and grain direction.

It's One Part of the Decision

Hardness is useful to know, but it’s just one factor. Janka doesn’t tell you how a timber reacts to heat or humidity, how stable it is, or how easy it is to cut and install.

Some of the hardest woods can be difficult to work with. Others, even if softer, might be more stable or forgiving on-site.

At Greenhill Timbers, we look at the whole picture, not just the numbers. All our timbers are structurally graded and covered by a 25-year guarantee. We'll help you pick something that works for your project, not just on paper.
