Sawn UC4 Brown Treated Incised Post 100 x 100mm 2400mm FSC

What is incising?

When a piece of timber has been incised, this means that a bladed machine has made tiny incisions along the surface of the timber. Incising allows preservative treatment to penetrate further into the timber, increasing its life span without affecting its strength.

What is UC4?

Use Class 4, or UC4, is a class within BS EN 335-2 that determines where timber products are or are not suitable for use. If a timber product meets UC4 classification, that means that it is suitable to be used in ground contact.
