Incised Round Posts with 15 Year Warranty

Our round posts are now almost all 15 Year Warranty stock, the warranty being a manufacturers warranty – see our Warranties page for more details. Machine rounding of posts produces a more regular post size than traditional peeling would.  We now carry 73mm machined (instead of 2”-3”), 88mm machined (instead of 3”-4”) and 106mm machined rounded.

The machine rounding of these posts means they can be treated with Next Generation Tanalith E preservative also known as Tanalith T8000 Technology.  Key to the process is the incising of the round posts which allows deeper penetration of the Tanalith preservative.  The posts are incised using the “Excalibur-R” process. To make identification easier all eligible posts are identified by a nail with year of manufacture driven into the top of each post.

The Tanalith treatment gives the preserved timber a green hue which mellows to grey. Most importantly this treatment provides protection against fungal and insect attack.
