| Q. |
What
is our wood density? |
| A. |
Our
timber is primarily sourced from the high density region
of Nelson which also has the highest average tree age
in NZ. New Zealand pine exhibits variations
in wood density related to the locality in which it is grown,
genetic make-up, silvicultural treatment, the part of the
tree from which the wood comes and age at harvest. Density
is correlated to important qualities such as timber strength,
machining and finishing properties. NZ pine wood density
is well suited for high value remanufacturing.  |

| Q. |
What
is NZ Pine's strength properties? |
| A. |
NZ
pine's strength and stiffness properties generally cover
the range of commonly used structural softwoods.

| Q. |
Is
Southpines timber cut from plantation forests? |
| A. |
Yes.
New Zealand is a world leader in plantation forest management
and the pine estate is managed on a sustained yield basis.
Nelson is NZ's second largest export region for forest/wood
products. |
| |
|
|
| Q. |
What
it's machining properties? |
| A. |
The
superior machining properties and its ease of moulding,
turning, planing, joining and furniture manufacture are
strong features of NZ pine.
Comprehensive trials conducted at NZFRI, in the United
Kingdom and by the University of California have shown
that New Zealand pine compares very favourably with softwood
species commonly used in Europe, North America & Asia
for higher value products.

| Q. |
Does
Southpine kiln dry it's timber? |
| A. |
Yes.
Southpine as a "NZ Dri Licencee" prides itself
on producing high quality stress free and consistently dried
New Zealand Pine. We have 7 kilns: 2 x accelerated conventional
kilns (80°C - 90°C, 3 to 5 days drying time),1 x
high temperature kiln (105°C - 130°C, 12-36 hours),
and 4 x medium temperature kilns (80°C - 105°C,
2 to 4 days) |
| |
|
|
| Q. |
Do
we preservative treat our timber? |
| A. |
When
timber is tantalised it is resistant to fungal degrade and
insect attack. NZ pine's sapwood is extremely permeable
to preservatives, permitting total penetration rarely achieved
with other softwood species. Southpine uses Tanalith CCA
in H3 (exposed to weather) and H4 (ground contact/landscaping).
Products include post, palings, decking, framing etc.
|
| |
|
|
| Q. |
Does
Southpine use anti-sapstain/ bluestain treatment? |
| A. |
Yes.
Southpine uses Hylite Clear (liquid fungicide and anti-sapstain).
|
| |
|
|
| Q. |
Is
NZ Pine easy to stain? |
| A. |
Our
pine is an extremely versatile wood and and readily accepts
the many stains that are available with extremely good penetration
and consistency. |
| |
|
|
| Q. |
How
is the timber transported? |
| A. |
The
majority of Southpine's export timber is shipped in 40-ft
containers and the balance is shipped breakbulk. Transsit
times range from 1-4 weeks. |
| |
|
|
| Q. |
How
many m3 fill a 40 ft container? |
| A. |
Approximately
38 - 42m3, depending on dimensions and lengths required.
|
| |
|
|
| Q. |
What
are Southpines lengths? |
