Commercial
Blackbutt
A premium Australian hardwood suited to large-scale specification, valued for its structural strength, long-term durability and consistent, refined appearance across extensive runs. Its pale caramel to golden-brown heartwood mellows evenly over time, with a straight, tight grain that maintains a cohesive look across multi-unit or high-traffic projects. Blackbutt's natural resistance to rot and termites, combined with excellent fire performance, makes it a preferred specification for demanding commercial applications — from stairs and structural beams to decking, cladding and joinery in high-exposure or high-use environments.

Why is Blackbutt used for commercial stair components?
Blackbutt is valued for its natural durability, termite resistance and fire performance, making it a preferred hardwood for commercial stairs where longevity under heavy use is essential.

Laminating adds dimensional stability across wide treads and stringers, reducing movement over time while retaining Blackbutt's natural strength — well suited to sustained commercial foot traffic.
