Clears and cutting grades suitable for manufacturing. Able to produce special
sizes and specifications to order.
Through good silviculture management, New Zealand pine logs come in
a range of qualities capable of yielding lumber grades to meet almost
any requirement.
Appearance grades (board grades): for finishing and furniture uses
can be either clear of knots or contain minor blemishes and tight knots.
They include:
- clear lumber free of knots and blemishes, used for high quality joinery, furniture and mouldings
- cutting grades for reprocessing to produce shorter clear lengths
with excellent machining, and gluing properties. These grades contain
large knots and blemishes which are removed by cross-cutting and
ripping. The resulting clear components are often finger-jointed and
edge-glued to produce mouldings and furniture.
Structural grades (framing grades): used primarily for construction
where strength and stiffness are important. The main factor influencing
a structural grade is the size and location of knots. Grades limit such
defects to meet specified strength requirements.
Industrial Grades: used in packaging for various products such as
pallets, cable drums, and concrete formwork. Grades contain a range of
knot sizes compatible with the final use.
New Zealand exporters are able to grade to most customer requirements. Common export grades include:
- Australia - Standards Association of Australia F5 and F7 structural grades (visual and machine stress graded)
- United States - Western Wood Products Association random width
lumber specifications including mouldings and better, shop and factory
grades.
- Japan - JAS structural grade specifications (which also include
glue-laminated and plywood grades). Industrial grades are also produced
including thinboard and a range of other grades to buyer specification.
