RAY CELLS
refers to the water-conducting cells in a living tree from which timber comes, and not the hardness or softness of the wood itself. You can see the differences between the cells when you look at wood samples though a microscope.

Radiata Pine - Pinus radiata
It grows up to 10 times faster than most eucalypts.
Radiata pine is themost widely grown exotic species in the world.
Radiata Pine - Pinus radiata
In NSW, radiata pine is grown in plantations around Bathurst, the snowy mountains and the southern highlands.
Forests NSW is the largest producer of plantation grown radiata pine in Australia, selling enough timber to construct about 25% of the houses built in Australia each year.

When impregnated
with preservative it may be used for fencing, pergolas, landscaping and
domestic decking.
House framing, flooring,
lining, joinery, mouldings,
and laminated beams. Preservative
impregnated poles for pole frame construction,
transmission poles and land poles.
ENGINEERING
Growing trees absorb carbon dioxide from the atmosphere and store the carbon so efficiently that about half the dry weight of a tree is carbon.
The carbon remains locked up for the life of the wood,
even when it is used for building products or furniture.
Wood is a natural, renewable material that can help tackle
climate change.
Why use wood?
