Turpentine is a large tree species occurring along the eastern coast of Australia from Bateman's Bay in New South Wales to Cooktown in North Queensland.
The true wood of this species ranges in colour from deep red to red-brown. Sapwood is distinctively paler, often creamy. The texture of Turpentine timber is fine to medium but often wavy, with interlocked grain. It is relatively free of gum veins.
Turpentine is extremely durable in above ground applications, where its life expectancy is in excess of 40 years. In-ground life expectancy ranges from 15 to 25 years. The timber of this species is termite-resistant, and untreated sapwood is immune to lyctid borer attack.
Turpentine is the main Australian species for marine pilings, as its high silica content makes it resistant to Teredinidae marine borers. Other engineering applications include wharf and bridge construction (as both sawn and round timber), railway sleepers, and mining timbers. Construction applications include general house framing, flooring and decking, lining and cladding. Turpentine is an excellent timber for dance floors. It is also used in the construction of plywood, laminated beams and bench tops, and for joinery and parquetry. Other applications include boatbuilding (knees, gunwales, planking, decking) and the production of oyster stakes, wine casks, mallets, and bearings.
Untreated timber of this species is equivalent to 'fire retardant treated timber' when tested in accordance with AS/NZS 3837. The bushfire rating of this species is expected to remain unchanged if assessed in accordance with proposed changes to the standard.
My old Freighter had 1” ply.
As the trailer had grain chutes, I guess it would have shouveled off easily.
It was in perfect condition apart from one small corner section down the back where water must have sat. Would have never seen a garage/shed until I bought it.
Mates with T&G floors always had the fear they would blow. We didn’t use ship lapped planks, just removed the bottom tongue off the last plank so it could drop in.
Did the same procedure replacing boards on squash courts when heavy players would put a foot through the floor. They were 32mm finished size Tasy Oak and pro players would still punch through up at the front wall.
