What is DPR?
DPR products are made from specially
selected low shrinkage hardwood species, planed with a smooth surface and
'pencil rounded' edges. Specialised sawing technology guarantees timber
which is dead straight, strong and accurate to size.
Using DPR products will speed up
construction by eliminating most preparation work.
They are available for use as framing,
sub floor framing, roof trusses, lintels, rafters, battens, posts and
decking. DPR products are particularly popular for pergolas, decks,
exposed joists and pole home framing.

How do you look after DPR products that
are to be used in an exposed application?
Step 1
If the timber is going to be used at a later date then it is important
to minimise surface checking *
by applying a base coat of an oil based primer and then storing the timber
in a flat, elevated position protected from the sun and rain.
Step 2
Before and during construction ensure that all timbers are primed,
including joints.
Step
3
Apply Two (2) top coats with either an acrylic or oil based enamel.
Please note: For advice relating to different paint systems
available it is recommended that you consult with your local paint
supplier.
* Surface checking is a natural process whereby
unseasoned timber dries out. As a consequence fine cracks (checking)
appear. These checks will close again with time once the centre of the
piece dries out. Coating the timber helps to minimise checking by slowing
down the moisture loss.

What's F14, F17 and Appearance grade
mean?
F14, F17 and Appearance grade are terms
used to grade unseasoned hardwood.
|
DPR is
supplied in three grades
|
| F14 |
Graded
for strength, not good looks |
| F17 |
Graded
for strength, not good looks** |
| Appearance
Grade |
Graded
for its lack of natural characteristics *** |
| |
| **F17
is stronger than F14, however 98% of the F17 spans can be
substituted with F14, which means substantial savings. Ask your
Architect or designer to apply the DPR Span tables to your project
for maximum value. |
| |
| ***Appearance
grade excludes natural characteristics such as gum vein, loose
knots, grub and insect holes. A rule of thumb is "if you
can't see any defect after you paint it then it's appearance
grade" NB...DPR is not supplied to
furniture grade specifications. |
