Manufacturing Curved Timber

Creating curved timber is a complex process and often difficult to effectively achieve on a commercial scale. Our Curved Timber Battens allow designers to create buildable, affordable solutions for curved concepts which are an increasingly popular design choice, likely due to the visual appeal and fluidity they bring to a space.

Words by Sculptform

Sculptform curved timber is moulded in our Australian factory by our team of experts. The processes we have adopted to curve our timber products are Steam Bending and Kerfing.

Why is timber able to curve?

Understanding what timber actually is, makes the curving process a lot easier to understand. Timber is made up of millions of fibres that run through its entire length. The fibres are visible by the naked eye and you can also see where fibres have bonded together to create structural integrity. A naturally occurring polymer called lignin is a powerful natural glue which bonds the timber fibres together. When timber is exposed to our curving processes the lignin is compromised and curving can occur.

Steam Bending

Suitable for interiors only, our process takes the traditional art of steam bending timber and applies it on a larger commercial scale. Through a complex process involving steam and heat, we can form spotted gum and white oak timber (in block and dome profiles) to the required shape without resistance.

This method creates seamless transitions between walls and ceilings and allows designers to create their curving vision unrestricted. While steam-bent timber lessens the number of joins required for a curved application, some joins are still required. Check out our join line options.

This technique exposes timber to steam to make it pliable. The heat and moisture from steam softens the lignin (the resin that binds the fibres) so that it can be bent and compressed. In this state, we are able to shape the piece of timber into the desired curve.

Just after we have curved the piece of timber, we continue to hold it in place while it cools down. This is called stress-relaxation. Then, once it has fully cooled down, it will maintain its curved timber form.

You can cut a curved shape out of a piece of timber, but that compromises the strength and durability of the timber and produces waste. The benefit of steam bending is that it manipulates the wood so that the grain continuously flows with the curve across the whole length. This is especially important on structural elements, where the curved piece is going to be supporting weight and taking stress.

While the steam bending and cooling process ensure the timber will hold the curve, grain and density variations can affect the overall curve. This is unavoidable due to the natural variation in timber.

Kerfing

When a sawblade cuts into a piece of timber this is called a kerf. Many of these kerf cuts along a timber batten provides the timber with more malleability so that it can be curved, this is what is referred to as kerfing.

The process of kerfing involves cutting along a timber batten with a saw blade multiple times in very close proximity. Each cut is the width of the saw blade and its teeth, so a very narrow cut

The kerf cut pierces the timber so that it nearly cuts the whole way through, but leaves the face of the timber batten untouched so that the length of timber stays in one piece. Once there are enough cuts in the timber for the amount of curve we need to create, we are able to shape it in place. These kerf cuts allow the timber batten to be flexed around a substructure to create the intended curve.

Kerfed pieces of timber are suitable for interiors and sheltered exteriors. Timber species that we can curve through our kerfing method include blackbutt, spotted gum, white oak and vic ash in block profiles.
