Poles are
used in a wide range of applications from dry dessert conditions
to marine jetties, (Some poles are still in service after
80yrs)
|
Wide range
of applications. Good service life.

|
Drying
|
The wood
seasons well. Hairline cracks dc appear on the surface of
the timber at times. Very few knots. Does not form knot
clusters, therefore no weakness due to knots.
