What Wood

There are numerous species of wood - each with their own unique characteristics that lend themselves to different applications.

This section discusses the process from tree to timber and what to consider in choosing the correct wood for the project. Structural materials include sawn timber, round timber, glue-laminated timber, panel products, plywood, and laminated veneer lumber.

Timber species

There are a range of New Zealand plantation grown exotic and indigenous species to suit a range of applications including structural, appearance, engineered wood products, furniture and joinery.

Log Quality, Conversion and Grading

Log quality is a function of size (diameter, length) shape (straightness, ovality, taper), and other external (branching) and internal (wood properties) features which can affect the suitability for a particular end use.

Structural materials

Wood has a number of excellent attributes, and can be used in a range of different building applications. From domestic buildings to low-rise commercial, industrial, public, civic and farm structures, the potential of wood is enormous.

Structural Concepts Ltd and Kanuka Engineered Wood Products Ltd

Key Features

At 60 metres wide with no internal supports, and made primarily from laminated timber, the building is a feat of innovative engineering designed to showcase the same product manufactured within.
Integral to the design are the large roof trusses which make up the majority of the 300 cubic metres of Pinus Radiata laminated wood used in the building.
For added strength, the bottom chords of the trusses have been laminated with Douglas Fir.
One of the many benefits of trusses is the ability to cover the required building width using smaller pieces of timber.
