How Timberlink Uses the Latest Technology to Give You the Most Consistent Stick of Timber.

Timber is often thought of as an old fashion industry. Lumberjacks and flannelette shirts might come to mind for the general public. The reality is Timberlink, like most thriving Australian manufactures are able to remain competitive by using the latest high-tech gear from around the world. So, we’ve put together a guide for our frame and truss partners to show how our timber gets from the forest to the frame with a level of quality and consistency not previously possible due to some incredible technological advances.

The Forest

At Timberlink we are proud to say that our pine only comes from plantations across Australia and New Zealand. Every tree that is harvested is replanted afterwards, Timberlink timber is a truly sustainable, natural resource, it is the ultimate renewable.

Incredibly, Australia’s pine plantations grow enough wood to replace the amount of timber required for an average single-story home in just 7 seconds!

It all starts at the nurseries where millions of seedlings are planted around Australia each year. After they have matured into viable seedlings, they are taken out and planted in time for spring.

While the pine trees are growing they are sucking up carbon dioxide, a fully-grown pine tree can suck up almost a tonne of CO2 each year.

The pine tree estates are carefully managed, and we now have the science to track how every stem is growing in the forest. A lidar detector that uses infrared and laser technology scans the forest and records not only size but also the density, fibre quality, altitude and the soil quality, giving the foresters all the information that they need to ensure the estates are managed to best meet our customers and the forests health in the future.

After somewhere between 28 and 32-years the pine trees are considered to be fully matured. Decades of selective genetic improvements and growth in knowledge have left us with a superior product in a variety of ways, for example slow growing seeds are now deployed in faster growing climates as slower growing timber enhances the density, making the timber stronger and stiffer.

The pine trees are 40-50m tall and around almost 1 metre in diameter. They are felled by harvesting machines that cut, scan, strip and then cut the log again into sizes that can be manufactured at our mills. The logs are then loaded onto trucks before being taken to one of our three mills; Tarpeena (South Australia), Bell Bay (Tasmania) and Blenheim (South Island, New Zealand).

There are strict rules in place that determine what can and what cannot be cut. These include limits on cutting within creeks, rivers and streams as well as natural habitats of native animals.

Softwood pine is the safe, environmentally friendly timber option.

The Mill

Timberlink is proud to be a Australian manufacturer and the reason this is possible is due to our world class manufacturing technology at the mills. It is this technology that allows us to provide our frame and truss customers with a more consistent piece of timber than ever before.

Once the logs come to one of our mills they are arranged by their lengths before being loaded into the mill, we remove the bark.

The Green Mill

Logs are loaded into the Green Mill where we laser scan each one, it’s no longer set and forget, we use science and engineering to get the absolute best out of each log. The scan uses sophisticated software that considers what our customers need and tries to balance this with the realities of using a natural product.

The log is then cut into strips of timber and the remaining wood is turned into chip to make paper products while the residue is used to power our kilns.

Kiln Drying

The timber is then separated by density into stacks before going into the kilns to be dried to reach the optimal moisture content, in Australia this is around 11%. The moisture content is important because it reduces the possible movement in the timber.

Timberlink has installed counter flow kilns (CFKs) in Tarpeena and Blenheim and is soon installing one in Bell Bay. This ingenious system slowly heats up the timber whilst circulating air and moves it through the 80m long kiln continuously over 16 hours.

Dr Trevor Innes, our head scientist and preeminent expert on kiln drying in Australia explains that “previously timber was heated at high temperatures in batch kilns multiple times until the moisture content was correct, this rapid heating can make the timber brittle, meaning our CFK’s result in a consistently stronger and superior product.”

We measure samples of timber for moisture after coming out of the kiln and again before going through the planer with a non-contact sensor. This incredible tool sets up an electric field to monitor the moisture content as the timber is passed through for an incredibly accurate reading.

The Dry Mill

Following the kilns our timber goes through to the dry mill to be assessed by some seriously high-tech gear to ensure the product is ready to go into frames, decks and pergolas around the country.

Each piece of timber first goes through our new Gilbert Planer which can mould up to 850 lineal meters of timber per minute, incredibly up to 300kms of timber per day is run through our Tarpeena dry mill alone. Once our timber goes through the planer it goes straight into our Lucidyne scanner.

Who is Lucy?

As a proud Australian manufacturer, we want to stay on top of the game, and that means staying at the forefront of technological advancements. This new Lucidyne scanner, or “Lucy” as we like to call her, uses AI technology to scan our wood with precision far beyond the human eye’s capabilities. This provides us with the assurance of a level of quality that wasn’t possible a few year ago.

Lucy uses multi-sensory imagery technology in conjunction with new self-training Perceptive Sight software to ensure each piece meets the structural properties required under Australian standards and also exceeds the minimum visual requirements.

“Lucy is just a great piece of high-tech gear” said GM of Operations Mike Bitzer. “She takes the guesswork out of timber grading.”

“Instead of looking at a piece and making assumptions based on out dated theories about knots or slope of grain, we can use precision engineering technology to give us the best outcome.”

“Like every tradie knows, you need the right tools for the right job or you’ll be left behind. Lucy uses similar AI technology to that used to drive driverless cars, to aggressively detect defects,” said Mike Bitzer. “If there are any defects that really impact the structural proprieties of the timber, Lucy will find them.”

Metriguard and Warp Tunnel

Following being scanned by Lucy we then test the boards for stiffness using the metriguard, physically bending the timber up and down and measuring how much load is required to create that bend.

After the Metriguard test the timber goes through the warp tunnel. This gives us a 3-dimensional cross section of the timber the software then compares the dimensions and can tell us if the board is warped or twisted.

This data is all fed into the Lucidyne optimising computer, where big data analytics is run to give us a grade for each stick of timber.


While still in the dry mill some of our timber will be treated for termite protection and become Timberlink Blue, guaranteed for 25 years. Some of our timber will be treated for outdoor structural and become low odour LOSP Timberlink Green.

The timber is then sorted into around 60 stacks depending on grade, treatment type and length before being put into packs.

From The Mill To You

The journey for our timber is far from complete though, it’s loaded up onto trucks and taken to stores across the country. Our Tarpeena mill in South Australia, which supply’s most of our FTMA members, sees almost 400 packs of timber leave per day.

Once it’s arrived at a frame and truss plant it’s turned into one of the most valuable things you can create, a family home.

I think you would agree it’s an incredible story from a truly incredible natural resource. Sustainable, renewable and a superior product, wood really in the ultimate renewable.
