DURA PINE (Radiata Pine or Pinus
Dura Pine timber is produced from the Radiata Pine tree.
Radiata Pine, also know as Monterrey Pine, is classed as a medium-density
softwood. Radiata Pine is a versatile timber and widely used
in the USA, Australia and New Zealand for the full range of structural and
decorative applications including framing, lining, glue laminated beams,
veneer and plywood. When appropriately treated, it can be used for many
exposed structural and non-structural applications.
Radiata Pine plays a significant role
in meeting the ever-increasing demand for sawn timber. As a well-managed
plantation tree, it can provide a renewable
resource providing dependable supply for generations to come due
to the fact that Radiata Pine is one of the world's most widely
planted plantation species and has the ability to grow to a large
diameter faster than almost any other tree species
The timber is low in density and fairly soft, often
with very wide annual growth rings.
We may suply:
SYP (Southern Yellow Pine) from the USA; solid sawn timber
(no finger jointing) S4S (4 sides planed) which is “CA-C”
treated. CA stands for Copper Azole. The C indicates the 3rd
variation (the 1st was A, etc). This product comes in
various dimensions mainly suitable for structural beams (no.
2 Framing grade) and for decking (Premium grade). This is
certainly a very suitable option but the timber will contain
knots, some wane, however it does not affect the strength.
The Pine that we use is FSC certified.
Finger jointed/laminated radiata pine columns & beams from
New Zealand. This is an engineered product specifically
designed for load bearing application. This product can
either be clear or with white or dark primer suitable for
immediate use. The treatment is “LOSP” (= Light Organic
Solvent Preservative) and similar to CA-C. This timber is
FSC certified (FSC number SW-COC-001657).
Both Pine products come with a 20 year (limited)
warranty against rot and termites.
The heartwood is light brown to yellow;
the sapwood white to pale yellow but often indistinct. The grain is usually
straight, but knots are common and growth rings are prominent.
In-ground contact: Class 4.
Outside above ground: Class 4.
Termite resistance of heartwood: Not resistant.

The above is the main reason that we do not advise
the use of this wood species for structural uses when it comes in
contact with soil, unless properly treated (see the paragraph about Dura
Radiata Pine can be used for both exterior and interior
applications. For interior uses it is kiln dried and for exterior uses it is
treated with preservatives, in some occasions kiln dried as well. Main use:
Flooring and decking boards, siding boards, cabinets, fencing, exterior
cladding, window sashes, pergolas, landscaping, shingles
What is Dura Pine
Dura Pine © is a brand
name of treated Radiata Pine wood and
has been developed to ensure structural performance. Its performance
characteristics provide the framework for achieving an excellent quality
of finish. Dura Pine has greater strength and stability due to its
special treatment, is more uniform in size, and reduces warping,
twisting and cupping. Dura Pine can be painted or stained immediately,
without waiting for the lumber to dry, unlike standard treated wood that
is still wet from treatment.
