Hyne Timber T3 Green

 

T3 Green is leading the charge against termites and fungal attack in outdoor applications. Both pose a very real risk to your structure, and then of course there’s Mother Nature to contend with. If you want your project to stand the test of time, protect it with T3 Green.

T3 Green has specifically been developed for use in exposed, above ground applications including deck and verandah bearers and joists; pergola, verandah and carport rafters and battens; verandah and patio beams; or any other external, above ground application requiring structural timber framing.

The treatment is safe, guaranteed for up to 25 years and approved for outdoor furniture, playground equipment, public projects and other applications where CCA treated timber is restricted.
For instructions on correct installation and maintenance of T3 Green please see our range of Technical Data Sheets.

Product information:

Species specification >
Manufactured from Plantation Softwoods sourced from managed forests.

Moisture content >
Basic definition – 
Moisture content is the mass of moisture present in wood divided by the mass of the wood with no moisture in it, expressed as a percentage.

Moisture content range – The moisture content of Hyne T3 Green is on average below 15% with a maximum of 21% per board. The moisture content is uncorrected. Therefore moisture meters used to confirm the moisture content need be set to Douglas-fir and 20ºC which are the default setting for most moisture meters.

Design information:

Design properties >
Mechanical properties have been determined in limit state format form with a comprehensive testing and evaluation program carried out by Hyne. The modulus of rigidity is calculated by using G = E/15. Density is a measured property and is determined as average seasoned density. However properties such as Bearing Strength Perpendicular to Grain, Bearing Strength Parallel to Grain, Shear Strength at Joints Details and Tension Strength Perpendicular to Grain are secondary properties which are depending on the strength group for the material and are determined in accordance with AS1720.1-2010. Further joint group are based on the material used and the groups are defined based on species and density as per AS1720.1-2010.
