Hoop Pine | Araucaria cunninghamii

Hoop Pine is a softwood widely used in general construction purposes, interiors, and for furniture.

Other Names: Queensland Pine, Colonial Pine, Moreton Bay Pine

Overview

Hoop Pine is a Queensland timber whose ease of use has made it popular for general construction purposes, flooring, joinery, shelving and cupboards, furniture, and plywood. When treated with preservatives it is suitable for outdoor uses such as fencing, pergolas, landscaping, retaining walls, and playground equipment. It is also used for a variety of non-architectural and non-building purposes, such as the manufacture of musical instruments, drafting instruments and brushware.

The heartwood ranges from pale cream to light yellow brown with little difference between heartwood and sapwood, though the heartwood is a little darker. It is a very fine and evenly textured wood with a straight grain. The growth rings are visible but not distinct and the figure is plain or mottled. 

The sapwood of Hoop Pine is easily treatable with preservatives, but the heartwood is not. It is resistant to lyctid borer attack, but not to termites. It is of low durability, with the heartwood having a life expectancy of less than seven years above ground and five below. 

Hoop Pine machines and turns well, but is not suitable for steam bending. It can be polished, painted and stained with ease, and works well with fittings and fastenings.
