The UC4 Collection

State-of-the art incising technology

Our state-of-the art incising technology guarantees that our chemical treatment can impregnate a minimum of 6mm into the timber. This ensures maximum protection for the product meaning that we can offer a guaranteed minimum 15-year life span and a UC4 classification.

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.

UC4 sleepers

UC4 sleepers complement the existing BSW sleeper range for gardeners or landscapers who want the added security of a 15-year warranty.

UC4 incised posts

Continued investment in cutting-edge technology enables us to offer an innovative range of UC4 incised posts with a warranty.

UC4 pine posts

High pressure treated in green or brown, our pine posts are treated to Use Class 4 for enhanced durability and peace of mind.

UC4 incised joists

Manufactured in the UK from homegrown spruce, our UC4 joists are incised all four surfaces to ensure a deeper preservative treatment.
