Grey Ironbark is the pinnacle of versatile Australian hardwoods, originally highly prized for its immense strength and natural durability.

This versatility has seen it expand into a new, limitless range of applications including cladding, flooring, decking and joinery products as well as feature posts and beams.

With a deep patina, the colour palette of the Grey Ironbark varies from a mahogany like appearance to dark shades of chocolate.

The heartwood ranges from pale brown to dark brown with occasional rich, red tones. Its grain is usually tight and straight.

Polishing beautifully, always ensuring a smooth finish, Grey Ironbark is a popular choice for many architects, designers and builders.

The incredible strength and durability of Grey Ironbark has resulted in it becoming the top choice for exterior applications over the years.

Today Grey Ironbark is also recognised for its rich, warm colouring and stunning patina, revealing its adaptability as an internal building material.
