128mm UC4i Green Treated PERMAPOST Incised Use Class 4 Round Posts (FSC® Mix), 2.1m
For fencing projects requiring high performance check out our range of Incised UC4 posts with a 15 Year Service Life. To achieve this quality the posts are kiln dried, incised and then pressure treated in a vacuum. This is vital to achieve Use Class 4 grading requirements, essential when timber is in ground contact or frequently subjected to wetting.
Round posts have been associated with agricultural fence installations for many years, but some posts have started to fail after 3-4 years. This happened at a time when the chemical constituents of the preservatives were significantly changed. It appears that the new eco-friendly chemicals were kinder, but also less effective on harmfull bacteria and insects.
The UK‘s increasingly warmer and wetter weather has made conditions damper and easier for insects and timber rotting bacteria to survive. However, progress in timber preservatives means that a 15-Years Guarantee is realistic providing that the incised Permaposts are used correctly see here
Pressure-treated fencing posts are strong machine-rounded stakes, the Tanalith preservation is to protect against rotting and damp. The treatment process begins with the timber being kiln-dried to reduce the moisture content down to around 28%. The preservative is then added to the timber in a high-pressure vacuum to achieve deeper penetration of preservative. The intense treatment is intended to extend the post’s life to approximately 15 years.
These machine rounded posts are normally available in 2.1 metres in length. Our timber posts are typically used in agricultural fences, animal and farm fencing.
