Charltons use Wolmanit ® CX pressure treated to UC4 level for all of our products; including all softwood 5 bar and pedestrian gates. UC4 is normally used for wood in ground contact so our gates are treated to the highest level.

These compounds used prevent & combat wood-destroying fungi including those causing soft rot. It also combat insects such as termites. Extensive international testing has confirmed the effectiveness of this product. The treatment is based on Copper HDO, a fungicide that has been successfully used in wood preservation for many years. It has undergone some of the most intensive toxicological testing of any wood preserving fungicide in the world.
