Description

Blackbutt 120x45mm F27 is a high-performance native hardwood widely used across Australia for structural and architectural purposes. Our 120 x 45mm F27 DAR profile is kiln dried to reduce movement and improve strength, and dressed all round to ensure a consistent, clean appearance for exposed or hidden applications.

This larger profile offers strength and coverage suited to framing, bearers, beams, rafters, and structural members in demanding residential and commercial builds. With Class 1 durability, natural termite resistance, and compliance with BAL29 bushfire zoning, Blackbutt is both practical and visually appealing.
