American white oak has a pale yellow-brown color with a pinkish tint, straight grain, and a silver grain figure on quarter-sawn wood due to its broad rays. Northern Oak grows slowly, yielding lightweight wood deemed better than the faster-growing, harder Southern oak. US forests prioritize sustainable management and environmental conservation.

American White Oak

Australian Oak is a mixture of two Eucalypt species. It ranges in colour from pale pink to brown straw. It is straight, open and even grained with a uniform texture, usually all quartersawn for stability with excellent staining properties. Victorian ash carries independent PEFC certification.

European Beech heartwood and sapwood are cream to pale pink in colour with a straight grain and fine, even texture. It is common practice to steam the timber, which turns it to a darker pink-red colour.

European Beech

The wood is pale yellow-white with distinct annual rings, straight grain, tight knots, and a fine texture. It's dense for a softwood due to slow growth, moderately durable, with heartwood resistant and sapwood moderately resistant to preservative treatment. Larch dries fairly quickly, with slight degrade, but kiln drying is effective.

European Larch

European Oak heartwood is light tan to biscuit colour and usually straight grained but irregular or cross-grained material can occur. Characteristic silver grain figure on quartered surfaces due to broad rays.

European Oak
