Description

Blackbutt 240x45mm F27 is one of Australia’s most trusted native hardwoods for structural work due to its high strength-to-weight ratio, neutral tones, and excellent durability. The 240 x 45mm F27 DAR profile is kiln dried to reduce movement and dressed all round to provide a premium, finished surface.

Its extra width and thickness make it ideal for large-scale structural applications such as long-span beams, heavy joists, exposed rafters, and feature timber elements. This profile complies with BAL29 bushfire regulations, meets Class 1 durability ratings, and offers natural termite resistance—making it a standout choice for both commercial and residential builds.
